    The growth of human lymphoid cell lines was suppressed by human peripheral T cells in the presence of immune complexes (IC). T cells bearing IgG receptors (TG cells) were, but T-non-G cells and non-T cells were not, active as effectors of cytostasis which was induced by IC-mediated bridging of the target and effector cells via Fc receptors. We propose that this phenomenon be called 'immune complex-dependent T cell-mediated cytostasis' (IDTC) and suggest its possible role in IC-mediated tissue injury, especially where T cell infiltration is observed. TG cells from healthy individuals suppressed Ig production and were cytotoxic effectors upon interaction with IC. However, the cytotoxic effectors seem to be distinct from the suppressors of Ig production since TG cells from rheumatoid arthritis patients showed dissociation between these two functions: they displayed cytostasis but had only little suppressive effect on the B cell response.

    T Cell Activation and Clonal Selection

    T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

    Cytotoxic T Cells-mediated Immune Response

    Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
    Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

    Immunodeficiency Diseases

    Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
    There are three main causes of immunodeficiency disorders...

    Hypersensitivity Reactions: Cytolytic Reactions

    Type II hypersensitivity involves IgG and IgM antibodies targeting cell surface antigens, leading to cell destruction. This can occur through complement activation, antibody-dependent cell-mediated cytotoxicity (ADCC), or acting as opsonins for phagocytosis. When excessive, these reactions cause significant tissue damage.Drug-induced hemolytic anemia is a common example, where drugs like penicillin or cephalosporins bind to red blood cells, forming drug-protein complexes. These complexes...

    Hypersensitivity Reactions: Immune-Complex Reactions

    Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
