So we know that alpha beta T cells only bind to those antigens found on either the class one and class two major histocompatibility complex on these antigen presenting cells. But what about the gamma delta T cells? What types of antigens can these gamma delta receptors actually bind to? Well, it turns out that the gamma delta T cells don't actually need the MHC class one or MHC class two complexes to actually bind to our antigens. In fact, these gamma delta T cells can bind to fully intact antigens that have not yet been degraded by other wide blood cells. For example, the macrophages and the other antigen presenting cells.
