An antigen-presenting cell (APC) or accessory cell is a cell that displays an antigen bound by major histocompatibility complex (MHC) proteins on its surface; this process is known as antigen presentation. T cells may recognize these complexes using their T cell receptors (TCRs). APCs process antigens and present them to T cells.
EPCR is a transmembrane glycoprotein receptor that plays a crucial role in regulation of blood coagulation, inflammation, and vascular integrity. Its ability to enhance the anticoagulant activity of protein C, modulate inflammatory responses, and maintain endothelial barrier function highlights its importance in homeostasis maintenance. [8]
The minimum bactericidal concentration (MBC) is the lowest concentration of an antibacterial agent required to kill a particular bacterium. [1] It can be determined from broth dilution minimum inhibitory concentration (MIC) tests by subculturing to agar plates that do not contain the test agent.
A laboratory fermentation vessel Microorganisms are essential tools in biotechnology , biochemistry , genetics , and molecular biology . The yeasts Saccharomyces cerevisiae and Schizosaccharomyces pombe are important model organisms in science, since they are simple eukaryotes that can be grown rapidly in large numbers and are easily ...
CD4 is a co-receptor of the T cell receptor (TCR) and assists the latter in communicating with antigen-presenting cells.The TCR complex and CD4 bind to distinct regions of the antigen-presenting MHC class II molecule.

The water-accessible surface area of an IgG antibody. Immunoglobulin G (IgG) is a type of antibody.Representing approximately 75% of serum antibodies in humans, IgG is the most common type of antibody found in blood circulation. [1]
Flagellin perception in Arabidopsis thaliana functions via the receptor-like-kinase FLS2 (FLAGELLIN SENSING 2). [15] Upon flg22 detection, FLS2 quickly binds to BAK1 (BRI1-associated kinase 1) to initiate signalling by reciprocal transphosphorylation of their kinase domains. [ 16 ]
