The four major blood groups are based on whether or not you have two specific antigens — A and B. Doctors call this the ABO Blood Group System. The third kind of antigen is called the Rh factor.

The nanoparticle cores were formed by desolvating influenza M2e antigen and coating it with hemagglutinin (HA) antigen via biotin–streptavidin conjugation. LBL modification promoted nasal delivery and ...

which is the fundamental building block for the ABO blood group system. In normal individuals, the H antigen serves as the base structure for building A and B antigens. In Bombay blood group ...

The initiation of T-cell–mediated antitumor immune responses requires the uptake and processing of tumor antigens by dendritic cells and their presentation on MHC-I molecules. Here we show in a ...

Consequently, a single antibody molecule can simultaneously bind two identical epitopes on the same antigen. Diagram of an antibody structure showing its key components, including antigen binding ...

Using Apc min/+ mice, a mouse model for intestinal tumorigenesis, and antigen-free diet, we report here that food antigens serve this function in the small intestine. By depleting Peyer’s patches (PPs ...

She has tried dozens of COVID-19 antigen tests—including while sick with COVID-19. Flu is (still) surging nationwide. You can test for flu infection at home, using any of the combination Covid ...

The control MSN-DLDH was incubated in artificial intestinal fluid under the same condition. In order to determine whether the vaccine could release the antigen normally after treatment in an acidic ...

This work provides a clear molecular description of immune evasion by a persistent virus. It also establishes the molecular structure of TAP to facilitate mechanistic studies of the antigen ...
