BCEls

BCEls, or B-cell epitopes, are short peptide sequences that are recognized by the immune system's B cells. These epitopes are typically found on the surface of antigens, which are foreign substances that the body recognizes as non-self. When a B cell encounters an antigen, it can bind to the BCEl on the antigen's surface, triggering an immune response. This response can lead to the production of antibodies, which are proteins that help neutralize or eliminate the antigen. BCEls play a crucial role in the adaptive immune response, as they help the body distinguish between self and non-self, and initiate an appropriate response to foreign invaders. The identification and characterization of BCEls are important in the development of vaccines and immunotherapies, as they can be used to stimulate a specific immune response against a particular pathogen or disease.
