Gene therapy is a revolutionary approach aimed at treating various diseases by manipulating the expression of specific genes. The composition and formulation of ultra-deformable vesicles play a crucial role in determining their properties and performance as siRNA delivery vectors. In the development of ultra-deformable vesicles for siRNA delivery, careful lipid selection and optimization are crucial for achieving desirable vesicle characteristics and efficient siRNA encapsulation and delivery. The stratum corneum acts as a protective barrier, limiting the penetration of molecules, including siRNA, into the deeper layers of the skin. Ultradeformable vesicles offer a promising solution to overcome this barrier and facilitate efficient siRNA delivery to target cells in the skin. The stratum corneum, the outermost layer of the skin, acts as a significant barrier to the penetration of siRNA.These engineering approaches enable the production of uniform and well-defined vesicles with enhanced deformability and improved siRNA encapsulation efficiency. Looking ahead, advancements in ultra-deformable vesicle design and optimization, along with continued exploration of combination strategies and regulatory frameworks, will further drive the field of ultra-deformable vesicle-based siRNA delivery.

Drug resistance is an important factor for prostate cancer (PCa) to progress into refractory PCa, and abnormal lipid metabolism usually occurs in refractory PCa, which presents great challenges for PCa therapy. Here, a cluster of differentiation 36 (CD36) inhibitor sulfosuccinimidyl oleate sodium (CD36i) and stearoyl-CoA desaturase 1 (SCD1) siRNA (siSCD1) are selected to inhibit lipid uptake and synthesis in PCa, respectively. To this end, a multiresponsive drug delivery nanosystem, HA@CD36i-TR@siSCD1 is designed.

Aims: Carboxylesterase (Ces)1f is implicated in protection against hepatic inflammation, but it is unclear whether the enzyme has an influence in polarization of Kupffer cells (KCs), the innate immune cells mediating hepatic inflammatory injury including acute liver failure (ALF). In the present study, we aim to explore KC polarization induced by Ces1f in mice with lipopolysaccharide/D-galactosamine (LPS/D-GalN)-induced ALF. We adopted a novel delivery system, β-1,3-D-glucan-encapsulated Endoporter-siRNA particles, to specifically target KC Ces1f knockdown via tail vein injection in mice.

Peptide-based self-assembled nanosystems show great promise as non-viral gene and siRNA delivery vectors. In the current study, we designed and functionalized nanofibers for the delivery of siRNA, targeting and silencing EGFR gene overexpressed in triple-negative breast cancer. The nanofiber-mediated siRNA delivery was characterized in terms of zeta potential, morphology, and structural stability by circular dichroism spectroscopy.

Triple-negative breast cancer (TNBC) has been a clinical challenge due to its high recurrence and metastasis rates. Chemotherapy remains the primary treatment for TNBC after surgery ablation, but it lacks targeted specificity and causes side effects in normal tissues. Receptor tyrosine kinase-like orphan receptor 1 (ROR1) is significantly expressed in TNBC cells, and small interference RNA (siRNA) targeting ROR1 can effectively suppress ROR1 gene expression, thereby inhibiting proliferation and metastasis.
