Germinal centre-independent memory B cells are generated from CD38 + GL7 + activated B cells. These memory B cells may maintain broad reactivity to the activating pathogen. B1a and B1b cells can ...

These antigen-experienced lymphocytes constitute the memory cells of the animal 4. In addition to memory B cells and memory T cells, which reside mainly in the peripheral lymphoid system ...

There's still a lot of uncertainty about how exactly the immune system responds to the SARS-CoV-2 virus. But what's become clear is that re-infections are still very rare, despite an ever-growing ...

In a recent study posted to the bioRxiv* preprint server, a team of researchers examined the memory B cell repertoire of individuals immunized with three doses of mRNA-based coronavirus disease ...

Scientists are opening up new prospects in the field, with the triggering of memory B cells directly in the lungs looking to be a promising avenue. At present, the vaccines are administered ...

In a recent study posted to the bioRxiv* preprint server, researchers evaluated memory B and T cell responses to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) before and after ...

Researchers at McMaster University and the Danish pharmaceutical company ALK-Abello have discovered a new type of memory B cell with unique features and a unique genetic signature that could be a ...

In immunology, a profusion of different cell surface markers is used to identify and separate immune cell types. In the novel memory B cell subset, FcRL5 acts as a surrogate marker for positive ...

These effector memory B cells appear to be poised for a rapid serum antibody response upon secondary challenge one year later, Anoma Nellore, M.D., Fran Lund, Ph.D., and colleagues at the University ...

Scientists have clarified the mechanism for inducing germinal-center B cells' differentiation into memory B cells, immune cells that remember antigens, at the molecular level. A group of ...

B cells are a type of immune cell that produces antibodies that help fight off infections. However, they can also cause allergies, a common chronic disease. The new cell, type-2 memory B cell (MBC2), ...

image: This study compares the immune characteristics of patients with COVID-19 vaccine breakthrough against their close contacts who are vaccinated and not infected. Memory B cell levels differed ...
