Bcl6 gene sculpts helper T cell to boost antibody production

...In germinal centers, the B cells not only proliferate but they also undergo hypermutation in their immunoglobulin genes so they can produce a diverse class of antibo...are likely producing the wrong type of antibody at great volume. Genetic hypermutation among B cells in germinal centers creates a hotbed of genomic instability, ...

Yale study offers insight into possible cause of lymphoma

...tations and an increased risk of cancer." The lymph system is made up of infection-fighting B cells. Schatz and his colleagues examined the somatic hypermutation (SHM) process, which introduces random mutations in B cells' antibody genes to make them more effective in fighting infection. SHM occurs in two st...
