Extracellular vesicles (EVs) are gaining recognition as promising therapeutic carriers for immune modulation. We investigated the potential of EVs derived from HEK293FT cells to stabilize and deliver interleukin-10 (IL-10), a key anti-inflammatory cytokine. Using minicircle (MC) DNA vectors, we achieved IL-10 overexpression and efficient incorporation into EVs, yielding superior stability compared to free, recombinant IL-10 protein.

Targeting tumor angiogenesis with safe endogenous protein inhibitors is a promising therapeutic approach despite the plethora of the first line of emerging chemotherapeutic drugs. The extracellular matrix network in the blood vessel basement membrane and growth factors released from endothelial and tumor cells promote the neovascularization which supports the tumor growth. Contrastingly, small cleaved cryptic fragments of the C-terminal non collagenous domains of the same basement membrane display antiangiogenic effect.

Somatic cell nuclear transfer (SCNT), or cloning, is used to reprogram cells and generate genetically identical embryos and animals. However, the cloning process is inefficient, limiting its application to producing valuable animals. In swine, cloning is mainly utilized to produce genetically modified animals.

In phage display technology, exogenous DNA is inserted into the phage genome, which generates a fusion protein with the phage coat protein, facilitates expression and promotes biological activity. This approach is primarily used to screen antibody libraries owing to its high library capacity and fast technical cycle; additionally, various types of genetically altered antibodies can be easily produced. In this study, we fused the pIII structural protein of the M13K07 phage with a scFv created by connecting the VH and VL domains of an anti-IFN-γ antibody.

The current work presents comparative assessment of affinity of the designed DNA aptamers for extracellular domain of the human epidermal growth factor receptor (EGFR*). The affinity data of the 20 previously published aptamers are summarized. Diversity of the aptamer selection methods and techniques requires unification of the comparison algorithms, which is also necessary for designing aptamers used in the post-selection fitting to the target EGFR* protein.
