The process dependent upon B cell antigen receptor signaling in response to self or foreign antigen through which B cells are selected for survival. The process of providing, via surface-bound receptor-ligand pairs, a second, antigen-independent, signal in addition to that provided by the B- or T cell receptor to augment B- or T cell activation. Any process that stops, prevents, or reduces the frequency, rate, or extent of an immune system process. Any process that modulates the frequency, rate, or extent of an immune system process. The somatic process allowing for the production of immune receptors whose specificity is not encoded in the germline genomic sequences. The process initiating the mucosal immune response which entails the apical-to-basolateral delivery of soluble and particulate antigens to underlying mucosal-associated lymphoid tissue. A process that directly activates any of the steps required for tolerance, a physiologic state in which the immune system does not react destructively against the components of an organism that harbors it or against antigens that are introduced to it. Any process that activates or increases the frequency, rate, or extent of an immune system process. The movement of a leukocyte within or between different tissues and organs of the body. The process by which T cells that express T cell receptors that are restricted by self MHC protein complexes and tolerant to self antigens are selected for further maturation. Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end. Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat. Any process of the immune system that occurs as part of an immune response. A change in morphology and behavior of a leukocyte resulting from exposure to a specific antigen, mitogen, cytokine, cellular ligand, or soluble factor. Any process that initiates an immune response. The process by which an antigen-presenting cell expresses antigen (peptide or lipid) on its cell surface in association with an MHC protein complex. The process whose specific outcome is the progression of an organismal system whose objective is to provide calibrated responses by an organism to a potential internal or invasive threat, over time, from its formation to the mature structure. A system is a regularly interacting or interdependent group of organs or tissues that work together to carry out a given biological process. null The process of regulating the proliferation and elimination of cells of the immune system such that the total number of cells of a particular cell type within a whole or part of an organism is stable over time in the absence of an outside stimulus. Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats.
