Article Synopsis
  • Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment, enhancing survival rates for patients with advanced cancers like melanoma and lung cancer by boosting the immune system's response to tumors.
  • These therapies target specific proteins (PD1, PD-L1, CTLA-4) that regulate T cell activity, which helps the immune system identify and attack malignant cells.
  • However, ICIs can cause serious cardiac side effects, such as myocarditis, leading to significant health risks, prompting a need for ongoing research and understanding of these immune-related adverse events.

Endophilin-A2 dependent VEGFR2 endocytosis promotes sprouting angiogenesis.

Nat Commun

May 2019

Cardiovascular Research Center, Department of Internal Medicine, Yale University School of Medicine, New Haven, CT, 06511, USA.

Endothelial cell migration, proliferation and survival are triggered by VEGF-A activation of VEGFR2. However, how these cell behaviors are regulated individually is still unknown. Here we identify Endophilin-A2 (ENDOA2), a BAR-domain protein that orchestrates CLATHRIN-independent internalization, as a critical mediator of endothelial cell migration and sprouting angiogenesis.

Mechanisms controlling ureter lenght and the position of the kidney are poorly understood. Glial cell-line derived neurotrophic factor (GDNF) induced RET signaling is critical for ureteric bud outgrowth, but the function of endogenous GDNF in further renal differentiation and urogenital system development remains discursive. Here we analyzed mice where 3' untranslated region (UTR) of GDNF is replaced with sequence less responsive to microRNA-mediated regulation, leading to increased GDNF expression specifically in cells naturally transcribing Gdnf.

Background And Aims: The depletion of the ozone layer allows overexposure of the skin to UV radiation, which is prolonged due to the increasing life expectancy, together with inappropriate life habits contribute to the increasing incidence of cutaneous malignancies. Plant extracts with antioxidant capacities are frequently employed as a means to protect skin against ultraviolet (UV) radiations, thus preventing skin cancers. In the present study we assessed a red grape seed extract (GSE) potential capacities to reduce ultraviolet B (UVB) radiation-induced reactive oxygen species (ROS) and subsequent apoptosis in a human keratinocytes cell line (HaCaT).

In recent years, the advances in stem cell research have suggested that the human body may have a higher plasticity than it was originally expected. Until now, four categories of stem cells were isolated and cultured in vivo: embryonic stem cells, fetal stem cells, adult stem cells and induced pluripotent stem cells (hiPSCs). Although multiple studies were published, several issues concerning the stem cells are still debated, such as: the molecular mechanisms of differentiation, the methods to prevent teratoma formation or the ethical and religious issues regarding especially the embryonic stem cell research.
