What Does BLS Stand For?

BLS stands for Bare Lymphocyte Syndrome

Bare Lymphocyte Syndrome (BLS) is a rare immunodeficiency disorder characterized by the absence or malfunction of lymphocyte surface markers essential for the proper functioning of the immune system. It results from genetic mutations affecting the major histocompatibility complex (MHC) molecules, leading to a reduced ability to present antigens and activate T-cells. Individuals with BLS are highly susceptible to various infections, particularly viral and bacterial pathogens, and may require early medical intervention, including immunoglobulin therapy and potential bone marrow transplantation to enhance immune function.
