Researchers Find Functions of 2 Types of B Cells
B cells are the arms factories of the immune system, producing antibodies that target invading microbes for destruction. Generally, B-1 cells have been thought to play a major role in the innate immune response -- the type of immunity that offers rapid, generalized responses to infections. Less understood has been any role in adaptive immunity -- in which the immune system develops a long-term immune response to an invader after vaccination or infection.
The researchers concluded that the B-1a cells regulate the innate immune response and the B-1b cells regulate the adaptive, long-term immune response. Knowing this, researchers can work on finding a vaccine mechanism for diseases such as B cell lymphomas.
