Summary: This collaborative work between UMC Utrecht with Radboud UMC and Maastricht University explores a novel approach to safely deliver RNA-based therapeutics during pregnancy. We demonstrated that targeted lipi nanoparticles (LNPs), functionalized with VHH nanobodies, remained within the maternal circulation without crossing into the fetal bloodstream. The findings were confirmed using an ex vivo human placenta perfusion model and multiphoton microscopy. This result forms a significant step toward developing safe, site-specific drug delivery systems for pregnant patients.

Pneumolysin-responsive liposomal platform for selective treatment of Streptococcus pneumoniae

Summary: 

• Summary: Streptococcus pneumoniae has become a leading cause of meningitis, sepsis, and bacterial pneumonia worldwide, with increased prevalence of antibiotic-resistant serotypes serving to exacerbate the issue. The main factor responsible for colonization and immune response escape in pneumococcal infections is the secreted molecule pneumolysin, which is a subset within a family of related toxins that form transmembrane pores in biological membranes. The present work aimed to examine the impact of liposomal cholesterol content for pneumolysin-induced release of the encapsulated antimicrobial peptide nisin. It was determined that a cholesterol content above 45 mol% was necessary to facilitate interactions with both purified pneumolysin toxin and S. pneumoniae culture. Antibacterial testing highlighted the ability of the developed platform to elicit a potent and specific bactericidal response in vitro against cultured S. pneumoniae when compared to a control strain, Staphylococcus epidermidis. It further improved viability of a fibroblast cell line upon S. pneumoniae challenge, outperforming free nisin.

 

 

 Flexible surface acoustic wave technology for enhancing transdermal drug delivery

April Best Paper 

Summary: This study develops a flexible acoustic wave patch for transdermal delivery of dextran macromolecules with various molecular sizes into agarose gels and porcine skin. We have achieved the maximum delivery depths of 1.1 mm (4 kDa) in agarose gel, and ~100 kµm (4 kDa) and ~25 µm (2000 kDa) in porcine skin. The key mechanisms were identified as mechanical agitation, localized streaming, and acousto-thermal effects, with also contribution from micro/nanoscale acoustic cavitation. Such the acoustic wave enhanced transdermal drug delivery depends on wave frequency and intensity, duration of applied acoustic waves, temperature, and drug molecules' molecular weight. It offers a promising solution for active, effective, and precise non-invasive drug administration.

Delivery of exogenous miR-19b by Wharton’s Jelly Mesenchymal Stem Cells attenuates transplanted kidney

: Renal ischemia-reperfusion injury (IRI) frequently occurs following kidney transplantation, and exosomes derived from umbilical cord mesenchymal stem cells (WJ-MSC-Exos) have shown promise in treating IRI in transplanted kidneys. The study demonstrates that abundantly present miR-19b in WJ-MSC-Exos prevents IRI in transplanted kidneys, while its absence abolishes the protective effects of WJ-MSC-Exos against renal IRI. Mechanistically, miR-19b suppresses glycogen synthase kinase-3β (GSK3β) expression, thereby stabilizing PDXK protein through direct binding. Treatment with WJ-MSC-Exos led to reduced PDXK levels and enhanced pyridoxine accumulation, ultimately mitigating IRI in transplanted kidneys and I/R-induced HK2 cell apoptosis. By elucidating the underlying mechanism of WJ-MSC-Exos, the study unveils novel therapeutic targets for post-kidney transplantation IRI and also demonstrates the potential for the clinical application of WJ-MSC-Exos in IRI treatment post-transplantation.

 Locally administered nanosuspension increases the delivery of estradiol for the treatment of vaginal atrophy in mice

Vaginal atrophy, affecting up to 57% of post-menopausal women, causes symptoms like vaginal burning and dysuria. Estradiol hormone replacement therapy is often prescribed, but traditional vaginal products may lead to side effects such as increased discharge and local tissue toxicity due to hypertonic formulations. We instead developed a novel estradiol nanosuspension (NS) formulation coated with Pluronic F127 for enhanced vaginal delivery. Compared to the standard Estrace cream, this formulation demonstrated improved estradiol delivery to vaginal tissues in pharmacokinetic studies. Using a murine model of post-menopausal vaginal atrophy (ovariectomized mice), the study showed equivalent efficacy in promoting vaginal re-epithelialization with the estradiol NS and Estrace cream. Additionally, the estradiol NS was compatible with vaginal bacteria in vitro. These findings suggest that the Pluronic F127-coated estradiol NS is a promising alternative treatment for post-menopausal vaginal atrophy, potentially offering improved safety and effectiveness over existing therapies.

Unlocking the Potential of Nanomedicine: Advances in Precision Targeting Strategies

RGD-coated polymeric microbubbles promote ultrasound-mediated drug delivery in an
inflamed endothelium-pericyte co-culture model of the blood-brain barrier
https://link.springer.com/article/10.1007/s13346-024-01561-6
Drug delivery to the brain is limited by the blood-brain barrier (BBB). Sonopermeation, which
combines ultrasound (US) and microbubbles (MBs), is a promising strategy to temporarily
open the BBB and enhance drug delivery. We developed an advanced in vitro BBB model
using human cerebral endothelial cells and pericytes to study the effects of sonopermeation
on the delivery of a large polymeric drug carrier (pHPMA) and a small molecule drug
(ribavirin) under normal and inflamed conditions. By measuring trans-endothelial electrical
resistance (TEER), we found that sonopermeation significantly reduced the TEER values
and increased the translocation of pHPMA. Inflammation was induced with tumor necrosis
factor, mimicking the conditions in tumors and CNS infections. RGD-coated MBs specifically
targeted inflamed endothelium, enhancing the delivery of both pHPMA and ribavirin across
the BBB. Our study demonstrates how combining in vitro BBB models with targeted
sonopermeation can optimize drug delivery to the (inflamed) brain, laying the foundation for
future research.

Nanoemulsions and nanocapsules as carriers for the development of intranasal mRNA vaccines.

https://link.springer.com/article/10.1007/s13346-024-01635-5

This manuscript demonstrates rational design of intranasal mRNA vaccines based on two delivery platforms, nanoemulsions (NE) and nanocapsules (NC), developed during the COVID-19 pandemic (2019-2023). First, we screened numerous NE and NC prototypes for cellular transfection, cytotoxicity, and intramuscular administration using model mRNAs. Second, we identified two promising candidates of NE and NC with their sizes close to 100 nm and a positive charge (NE) or neutral charge (NC). Both candidates induced strong antigen-specific CD8+ T cell responses intranasally, while the response was greater for the NC prototype. The study highlights the importance of optimizing nanocarrier compositions, surface properties, and lipid types in enhancing vaccine performance. 

 

The selection of animal models influences the assessment of anti-tumor efficacy:
promising sialic acid-conjugate modified liposomes demonstrate remarkable therapeutic
effects in diverse mouse strains
https://link.springer.com/article/10.1007/s13346-023-01502-9
Mouse models serves as a crucial tool for preclinical assessment of antineoplastic agents, but
the impact of physiological differences among mouse strains on in vivo antitumor efficacy has
been overlooked. Mononuclear phagocyte system (MPS) is the major player in clearance in
vivo, and differences in MPS among different strains may potentially impact the effectiveness of
antitumor preparations. We thus employed conventional liposomes (CL-EPI) and sialic acid-
octadecamine-modified liposomes (SAL-EPI) as model preparations to compare the therapeutic
effects in tumor-bearing KM, BALB/c, and C57BL/6 mice. The results demonstrated significant
variability in the efficacy of CL-EPI for tumor treatment across different mouse strains,
necessitating careful selection of animal models. SAL-EPI effectively targeted tumor sites by
binding to Siglec-1 on the surface of peripheral blood monocytes (PBMs) and achieved
uniformly improved therapeutic effect in different mouse strains. The sialic acid-modified
preparation is therefore expected to achieve a favorable therapeutic effect in tumor patients with
different immune states through PBMs delivery (Siglec-1 was expressed in both mice and
humans), thereby possessing clinical translational value and promising development prospects.

Intravenous injection of cyclosporin A loaded lipid nanocapsules fights inflammation and
immune system activation in a mouse model of diabetic retinopathy
Summary: https://link.springer.com/article/10.1007/s13346-023-01350-7

Inflammation and immune system activation are key pathologic events in the onset and
escalation of diabetic retinopathy (DR). Both are driven by cytokines and complement
originating from the retinal pigment epithelium (RPE). Despite the RPE’s pivotal role, there is no
therapeutic tool to specifically interfere with the RPE-mediated pathology of DR. Here, we
utilized lipoprotein-mimetic lipid nanocapsules to deliver the anti-inflammatory and
immunosuppressive drug cyclosporin A (CsA) to RPE cells. Using a mouse model of DR that
mirrors all pathologic aspects of human DR, we demonstrate that intravenously applied CsA-
loaded lipid nanocapsules comprehensively counteract inflammation and immune system
activation. One single injection suppressed the expression of pro-inflammatory cytokines,
dampened macrophage infiltration, and prevented macrophage and microglia activation in eyes
with DR. This work shows that CsA-loaded lipid nanocapsules can offer new avenues for the
treatment of DR.

Nebulizers Effectiveness on pulmonary delivery of alpha‑1 antitrypsin

Summary:https://link.springer.com/article/10.1007/s13346-023-01346-3
The administration of nebulized alpha-1 antitrypsin (AAT) to the lung represents an interesting
alternative to parenteral infusion for patients suffering from AAT genetic deficiency (AATD).
However, the nebulization of proteins can have a dramatic effect on their activity. In this paper, a
formulation of AAT for infusion was nebulized with a jet or a mesh vibrating system, whose
performance was compared in terms of aerosolization efficiency and preservation of AAT function.
The two nebulizers allowed satisfactory preservation of protein activity and provided equivalent
aerosolization performances, while the delivered dose was higher with the mesh vibrating system.
Nebulization of AAT proved to be a suitable administration strategy ready to be translated to the
clinical practice for direct lung delivery of the protein in AATD patients, either as a support therapy
to parenteral administration or, for subjects with a precocious diagnosis, as a means to prevent the
onset of pulmonary symptoms.

Neuronal differentiation and functional maturation of neurons from neural stem cells
induced by bFGF-chitosan controlled release system

Summary:https://link.springer.com/article/10.1007/s13346-023-01322-x
Available methods for differentiating stem cells into functional neurons require numerous
cytokines and neurotrophic factors, and the process is highly complex, slow, inefficient, and
costly for clinical implementation. Here, we demonstrate a bioactive material, basic fibroblast
growth factor (bFGF)-chitosan controlled release system, facilitates neuronal differentiation from
neural stem cells (NSCs) and the functional maturation of the induced neurons with high
efficiency. Immunostaining revealed that the neurons derived from NSCs expressed mature
immunomarkers of interneurons and excitatory neurons. We also found by patch-clamp that the
induced neurons exhibited diverse electrophysiological properties as well as functional
synapses. In vivo, we implanted bFGF-chitosan into lesion area in traumatic brain injury mice
and observed abundance of neuroblasts in subventricular zone and the presence of newborn
functional neurons in injury area, which integrated into synaptic networks. Taken together, our
efficient and rapid tissue engineering approach provides a means to generate functional
neuronal lineage cells from stem cells and potentially to treat brain injury and diseases.

 

Rapidly Dissolving Bilayer Microneedles Enable Minimally Invasive and Efficient Protein Delivery to the Posterior Segment of the Eye.- Best Paper August 2023 Issue
Summary

https://link.springer.com/article/10.1007/s13346-022-01190-x

The discovery of proteins that neutralize vascular endothelial growth factors can inhibit the
process of angiogenesis to restore eyesight in individuals with retinal vascular disorders.
However, a safe and effective means to deliver these protein drugs to the target posterior
segment is currently lacking. To this end, we developed dissolving bilayer microneedles (MNs)
possessing the potential to deliver proteins to the back of the eye in an efficient and minimally
invasive manner. A model protein, ovalbumin (OVA), was incorporated into MNs fabricated from
different polymers, including hyaluronic acid, polyvinyl alcohol (PVA) and polyvinylpyrrolidone
(PVP). Optimized PVA/PVP MNs demonstrated robust permeation of porcine sclera with > 75%
of the needle length penetrating the sclera while dissolving within 150 s. SDS-PAGE and OVA-
specific ELISA revealed that the bioactivity of OVA was retained during the manufacture of MNs.
In hen’s egg-chorioallantoic membrane test, MNs fabricated from all chosen polymers were
classified as non-irritants. Furthermore, ex vivo permeation studies showed that optimized MNs
mediated the penetration of 86.99 ± 7.37% of OVA through the sclera, twice that of the needle-
free patch (42.16 ± 3.95%), highlighting the capability of MNs to circumvent physical barriers
and promote protein delivery to the posterior segment of the eye. Overall, a novel, efficient, and
safe intraocular protein delivery system was successfully established.

Nanoparticle per-treatment for enhancing the survival and activation of pulmonary
macrophage transplant

Despite recent clinical successes of the chimeric antigen receptor T cell therapy in treating liquid
cancers, numerous challenges hamper its broader translation. Macrophage has been proposed
as an alternative given its abilities in promoting tumor infiltration, acquiring diverse antigens, and
continuously stimulating adaptive responses. However, poor survival of transplanted
macrophages and transient retention of anti-tumor phenotype have been major obstacles.
Leveraging on recent discoveries of nanoparticle strategies addressing these limitations, we
herein report enhanced survival and phenotypic retention of macrophage transplants in murine
lungs by pre-treatment with nanoparticles of varying degradation rates. Poly(ethylene glycol)
diacrylate nanoparticles prolonged survival of transplanted macrophages over untreated cells,
where nanoparticles increased the retention of transplanted cell counts by over 50%.
Furthermore, pre-treated macrophages more efficiently retained the pro-inflammatory-like
polarization state compared to macrophages pre-treated with a classical pro-inflammatory
stimulus, interferon-gamma, where CD86 costimulatory molecule expression was over 150%
greater in pre-treated macrophage transplants compared to untreated counterparts. These
findings provide an avenue for a major improvement in the lifespan and efficacy of macrophage-
based therapies and thus their broader therapeutic implementation.

Summary

Sustained antigens delivery using composite microneedles for effective
epicutaneous immunotherapy
Allergen-specific immunotherapy is an efficacious therapy for various allergic diseases such as
food allergy (FA). However, frequent clinical visits and potential adverse effects often hinder
patient compliance. Here, we proposed an implantable microneedle (MN) system composed of
OVA (antigen)-loaded silk MNs and a dissolvable, flexible polyvinyl alcohol (PVA) pedestal.
Once MNs are inserted into the skin, the PVA pedestal can quickly dissolve in the interstitial
fluid of the excised skin and implant the OVA-loaded silk MN tips in dermal layer as a sustained
antigen depot, thus inducing long-lasting immune response. After receiving 3 doses of MN-
based immunotherapy, the immune response in OVA-sensitized mice was successfully
suppressed, with no apparent side effects. Compared to conventional subcutaneous
immunotherapy, MN immunotherapy ameliorated systemic anaphylaxis more effectively even at
a lower dose, demonstrating the antigen dose-sparing potential of the proposed MNs. Moreover,
due to the prolonged release effect of silk-PVA composite MNs, the frequency of
immunotherapy can be significantly reduced. Overall, through prolonged skin exposure to
antigen, this implantable designed MN may offer a new therapeutic strategy for FA treatment
with significant improvements in efficacy and convenience.

Drug Delivery and Translational Research – Best Paper May 2023 Issue
Summary

Preterm born infants are often susceptible to necrotizing enterocolitis (NEC), a terrible disease associated with impaired intestinal barrier properties, and are often empirically treated with intravenous broad-spectrum antibiotics. Yet, it is unclear how this antibiotics exposure, as well as the way they are dosed, affects the intestinal barrier and minimizes the risk of developing NEC. We show that permeability rates through intestinal mucosa from piglets dosed with the combination of enteral and parenteral antibiotics were comparable to the rates in untreated piglets, whereas the piglets dosed with parenteral antibiotics had lower permeability rates. Interestingly, decreased permeability rates through the mucus alone were evident, suggesting that the change in the mucosa permeability to a large extent was caused by altered mucus permeability. Mixing the antibiotics with untreated mucus had no effect, suggesting that the altered properties of mucus were caused by other associated events induced by the antibiotics.

Drug Delivery and Translational Research – Best Paper April 2023 Issue
Summary
The analysis of gastrointestinal cellular permeation in pre-clinical drug development is widely
conducted, however the permeation of the overlying mucus layer is often overlooked. This is
attributed to a lack of understanding of the complexity of this layer, coupled with minimal
availability of experimental tools to quantify permeation through the turbid, viscous solution. Here,
a novel microfluidic device facilitates the observation of interactions between physicochemically
diverse nanocarriers and the mucin protein on a microscopic scale. This approach provides key
information on mucin-binding which may be lost with traditional methods and allows the
quantification of mucoadhesive as well as mucopermeating formulations. In addition, utilising a
complex biomimetic solution of proteins, lipids and salts which accurately mimics the chemistry and
rheology of native mucus within the device resulted in a 5.5-fold reduced permeation and 1.4-fold
reduced diffusivity of PLGA nanoparticles, compared to a more prevalent, simple mucus mimic.

 Circular RNAs (circRNAs) are a class of highly stable and closed-loop noncoding RNA that are
involved in the occurrence and development of hepatocellular carcinoma (HCC). We found that
high circ_0058051 expression was negatively correlated with the prognosis of HCC patients.
We also showed here that circ_0058051 knockdown attenuated the proliferation and colony
formation, while inhibited migration of HCC cells. The findings underscore the potential of
circ_0058051 as a therapeutic target for HCC. We synthesized a novel small interfering RNA
(siRNA) delivery system, PEG-PCL-PEI-C14-SPIONs (PPPCSs), based on superparamagnetic
iron oxide nanoparticles (SPIONs). PPPCSs protected the siRNA of circ_0058051 from
degradation in serum and effectively delivered siRNA into SMMC-7721 cells. Meanwhile,
intravenous injection of the PPPCSs/siRNA complex could inhibit tumor growth in the
subcutaneous tumor model. In addition, the nanocomposite was not toxic to the organs of nude
mice. Collectively, PPPCSs/si-circ_0058051 complex may provide a novel and promising
method of HCC treatment.

Thymoquinone (TQ) is a quinone-based phenolic compound with antioxidant and anti-
inflammatory activities, but its therapeutic utility has been underexplored due to inadequate
biological stability, short half-life, low hydrophilicity, and poor systemic bioavailability.
Tamanu oil-stabilized nanostructured lipid carriers (TQ-NLCs) enriched with TQ were
prepared and optimized using Box-Behnken design with the size of 153.9 ± 0.5 nm and
surface charge of -30.7 mV. The encapsulation efficiency and drug loading density were
found to be 84.6 ± 0.5 % and 14.8 ± 0.5 %, respectively. The TQ-NLCs assayed for skin
permeation for transdermal delivery where TQ-NLC provided roughly 15 times greater
permeation compared to aqueous solution of TQ. Tamanu oil displayed a synergistic anti-
inflammatory potential with TQ in comparison to TQ alone in carrageenan-induced paw
oedema model and Freund's adjuvant-induced arthritic model. The arthritic and X-ray scores
significantly reduced in TQ-NLC-treated and standard formulation-treated groups. Moreover,
serum pro-inflammatory TNF-α and IL-6 levels were significantly reduced in TQ-NLC-treated
group compared to the arthritic control group.

Summary: We introduce a novel antiviral nano-drug called SNAT (Smart Nano-Enabled
Antiviral Therapeutic) composed of taxoid (Tx)-decorated amino (NH 2 )-functionalized silver
nanoparticles (Tx–[NH 2 -AgNPs]). The particles are around 5 nm in diameter, positively charged
and stable for over three years at room temperature. We assessed the preclinical efficacy of
inhaled SNAT where we found that SNAP significantly reversed the body weight loss, reduced
the virus load in oral swabs, and improved lung health of hamsters infected with SARS-CoV-2.
Further, SNAT was found to be noncytotoxic and antioxidant, potentially quenching lipid
peroxidation, in human lung epithelial cells and dermal fibroblasts. Overall, our study
collectively highlights SNAT as a safe and potent antiviral platform against SARS-CoV-2
infection and potentially other respiratory viruses of epidemic and pandemic potential.
