Angio-microRNAs in diabetic foot ulcer-: Mechanistic insights and clinical perspectives.

Diabetic foot ulcers, as one of the chronic wounds, are a serious challenge in the global healthcare system which have shown notable growth in recent years. DFU is associated with impairment in various stages of wound healing, including angiogenesis. Aberrant expression of microRNAs (miRNAs) involved in the disruption of the balance between angiogenic and anti-angiogenic factors, plays a crucial role in angiogenesis dysfunction.

Tuning spacer length improves the functionality of the nanobody-based VEGFR2 CAR T cell.

Background: The chimeric antigen receptor-expressing T (CAR-T) cells for cancer immunotherapy have obtained considerable clinical importance. CAR T cells need an optimized intracellular signaling domain to get appropriately activated and also for the proper antigen recognition, the length and composition of the extracellular spacer are critical factors.

Results: We constructed two third-generation nanobody-based VEGFR2-CARs containing either IgG1 hinge-CH2-CH3 region or hinge-only as long or short extracellular spacers, respectively.

Exosomes derived from cancer-associated fibroblasts mediate response to cancer therapy.

Cancer-associated fibroblasts (CAFs) are the prominent stromal cell population in the tumor microenvironment (TME), which play an indispensable role in cancer progression and response to therapy. CAFs provide communication between tumor cells and surrounding cells by secreting soluble biomolecules and extracellular vesicles (EVs). Exosomes are small membrane-bound EVs that contain various cargos, including growth factors, non-coding RNAs (ncRNAs), cytokines, and chemokines.

Engineered Jurkat Cells for Targeting Prostate-Specific Membrane Antigen on Prostate Cancer Cells by Nanobody-Based Chimeric Antigen Receptor.

Background: Recently, modification of T cells with chimeric antigen receptor (CAR) has been an attractive approach for adoptive immunotherapy of cancers. Typically, CARs contain a single-chain variable domain fragment (scFv). Most often, scfvs are derived from a monoclonal antibody of murine origin and may be a trigger for host immune system that leads to the T-cell clearance.

T cell engineered with a novel nanobody-based chimeric antigen receptor against VEGFR2 as a candidate for tumor immunotherapy.

Solid tumors that are responsible for more than 85% of cancer death cases need angiogenesis for their growth and metastasis. Among antiangiogenic therapies, targeting the vascular endothelial growth factor receptor 2 (VEGFR2) that is over-expressed on tumor vasculatures has been a promising strategy. In this study, we developed a second generation nanobody (VHH)-based CAR T cell targeting VEGFR2-expressing tumor cells.

Construction of a chimeric antigen receptor bearing a nanobody against prostate a specific membrane antigen in prostate cancer.

Adoptive transfer of T cells expressing chimeric antigen receptors (CARs) is considered to be a novel anticancer therapy. To date, in most cases, single-chain variable fragments (scFvs) of murine origin have been used in CARs. However, this structure has limitations relating to the potential immunogenicity of mouse antigens in humans and the relatively large size of scFvs.

Using gold nanoparticles in diagnosis and treatment of melanoma cancer.

Several studies have been devoted to clear functionalization of gold nanoparticles (AuNPs) in different fields such as cellular and molecular biology, microbiology, immunology and physiology. In line with the high diagnostic value of AuNPs, its therapeutic application has been intensively developed in tumour therapy, in recent years. One of the best clinical applications of AuNPs is its use in targeted delivery of anti-cancer drugs.

Anti‑inflammatory effect of Migri‑Heal® in an in vitro inflammatory model of primary mixed glial cells.

Migri‑Heal®, is a novel herbal remedy that was introduced for the treatment of migraine headaches. Previous studies revealed that this drug may reduce nitric oxide (NO) in an in vitro inflammatory model. The aim of the present study was to investigate the anti‑inflammatory effect of Migri‑Heal® on primary mix glial cells stimulated with LPS.

Protective effects of erythropoietin against cuprizone-induced oxidative stress and demyelination in the mouse corpus callosum.

Objectives: Increasing evidence in both experimental and clinical studies suggests that oxidative stress plays a major role in the pathogenesis of multiple sclerosis. The aim of the present work is to investigate the protective effects of erythropoietin against cuprizone-induced oxidative stress.

Materials And Methods: Adult male C57BL/6J mice were fed a chow containing 0.
