BTK (Bruton tyrosine kinase)

Bruton tyrosine kinase (BTK) is an important enzyme in the body that helps regulate the immune system, particularly by aiding in the development and functioning of B-cells, which are crucial for producing antibodies to fight infections. Abnormalities in BTK can lead to immune disorders, such as X-linked agammaglobulinemia, where the body struggles to produce adequate immune responses. BTK is also a target for certain cancer treatments, as some cancers can exploit this pathway to grow and survive. Understanding BTK is key for developing therapies for both immune system disorders and specific types of cancer.
