      As tumors grow they acquire mutations, some of which create neoantigens that influence the response of patients to immune checkpoint inhibitors. We explored the impact of neoantigen intra-tumor heterogeneity (ITH) on anti-tumor immunity. Through integrated analysis of ITH and neoantigen burden, we demonstrate a relationship between clonal neoantigen burden and overall survival in Cited by: Superantigens; A) bind specifically to T helper cell receptors: B) bind without antigen specificity to the outer portion of T helper cells and antigen presenting cells (APCs) C) are bound inside specific MHC II antigens on APCs: D) bind to about 1 in 10, T cells: E) do not stimulate as many T helper cells as do antigens that bind with.

    Type 1 diabetes (T1D) is an autoimmune disease driven by the activation of lymphocytes against pancreatic β -cells. Among β -cell autoantigens, preproinsulin has been ascribed a key role in the T1D process. The successive steps that control the activation of autoreactive lymphocytes have been extensively studied in animal models of T1D, but remains ill defined in by: T-Cell Activation in Human Intestinal Mucosa: The Role of Superantigens JAMES AISENBERG,* ELLEN C.

      Interactions among different clones of CD4 + and CD8 + T cells are found in many immune responses, including T cell development, maturation, reconstitution, antigen recognition and different stages of T cell activation, and such interactions play an important role in the sustaining of immunologic homeostasis.[1,2] Although co-operation and competition between different clones of T Cited by: 8.   Recent preclinical and clinical studies have proved the long-standing hypothesis that tumors elicit adaptive immune responses and that the antigens driving effective T-cell response are neoantigens, i.e., peptides that are generated from somatically mutated genes. Hence, the characterization of neoantigens and the identification of the immunogenic ones are of utmost Cited by:

A drug known as RhoGAM, short for Rh immune globulin, can temporarily prevent the development of Rh antibodies in the Rh − mother, thereby averting this potentially serious disease for the fetus. RhoGAM antibodies destroy any fetal Rh + erythrocytes that may cross the placental barrier.
