AXL kinase is an attractive cancer target for drug design and it is involved in different cancers. A set of molecule databases with 1072 secondary metabolites from seaweeds were screened against the AXL kinase active site and eight molecules were shortlisted for further studies. From the docking analysis of the complexes, four molecules GA011, BE005, BC010, and BC005 are showing prominent binging. From the 100 ns of molecular dynamics simulations and ligand-bound complex MM-PBSA free energy analysis, two molecules BC010 (ΔG = -135.38 kJ/mol) and BE005 (ΔG = -141.72 kJ/mol) are showing molecule stability in the active site also showing very strong binding free energies. It suggests these molecules could be the potent molecules for AXL kinase.

Background: Alzheimer's disease (AD) is a neurodegenerative disease characterized by the presence of phosphorylated tau neurofibrillary tangles and extracellular deposits of amyloid beta plaques (Aβ) in the brain. Microglia cells have been proposed to be involved in amyloid plaque formation since activated microglia produce inflammatory cytokines that contribute to a hostile neuronal environment, exacerbating AD pathogenesis.
Method: We aim to evaluate if the pharmacological inhibition of the myeloid/microglial receptor tyrosine kinase AXL, with bemcentinib (BGB) could be used as a novel therapeutic approach for AD.

Ebola virus (EBOV) causes severe human disease. During late infection, EBOV virions are on the skin's surface; however, the permissive skin cell types and the route of virus translocation to the epidermal surface are unknown. We describe a human skin explant model and demonstrate that EBOV infection of human skin via basal media increases in a time-dependent and dose-dependent manner.

Overexpressed AXL kinase is involved in various human malignancies, which incurs tumor progression, poor prognosis, and drug resistance. Suppression of the aberrant AXL axis with genetic tools or small-molecule inhibitors has achieved valid antitumor efficacies in both preclinical studies and clinical antitumor campaigns. Herein we will report the design, synthesis, and structure-activity relationship (SAR) exploration of a series of anilinopyrimidine type II AXL inhibitors.

Since the major spike protein receptor is ACE2, an enzyme that regulates angiotensin II (1-8), this study tested the hypothesis that angiotensin II (1-8) influences the binding of the spike protein to its receptors. While angiotensin II (1-8) did not influence spike-ACE2 binding, we found that it significantly enhances spike-AXL binding.

Immune responses to tumors, comprising adaptive T cells and innate NK cells, arise very early in tumorigeneses and prior to detection of palpable tumors or before tissue pathology is evident. Yet, how nascent tumors evoke dendritic cell maturation and the resulting cytokine responses that are necessary for these effector anti-tumor immune responses is unknown. We have previously shown that CD91 expression on dendritic cells is important for immune surveillance, specifically for generating T cell and NK cell responses to nascent tumors.
