The B cell receptor (BCR) is a transmembrane protein on the surface of a B cell. A B cell receptor is composed of a membrane-bound immunoglobulin molecule and a signal transduction moiety. The former forms a type 1 transmembrane receptor protein, and is typically located on the outer surface of these lymphocyte cells.

Witryna4 paź 2024 · Definition. B cells or B lymphocytes are part of the adaptive immune response. Once activated, these white blood cells produce antibodies. B lymphocytes have further roles as antigen-presenting cells and cytokine secretors. This cell type is classified into four main groups: transitional, naïve, plasma, and memory B cells. WitrynaThe vast majority of pre-erythrocytic malaria vaccines elicit antibodies that primarily target the Plasmodium falciparum circumsporozoite protein (PfCSP), a major protein on the surface of sporozoites with a basic structure consisting of the N-terminus (N-CSP), the junction (N-Junc), the central repeat motifs, and the C-terminus (C-CSP), which ...
