<prompt> About SUPERANTIGENS true isImmune response is increased by 5Needs to be processed before presentationThey are presented by APCs to T cellDirectly attached to latrel aspect of TCR beta chain  <response>: Super antigens are molecules that can interact with antigen-presenting cells APCs and T-lymphocytes in a non-specific manner. These antigens do not involve the endocytic processing as required in typical antigen presentation. Interaction of superantigens with MHC class II molecules of the APC and the V domain of the T-lymphocytes receptor activates a large number of T-lymphocytes than conventional antigens. This leads to massive cytokine expression and immuno-modulation.Staphylococcal enterotoxins, exfoliative toxin and some viral proteins are examples of superantigens.Ref : textbook of microbiology, C P Baveja 5th edition pg no:95
