WebPeripheral tolerance describes the mechanisms that take place o utside of primary lymphoid . tissues to prevent lymphocytes from initiatin g potentially dangerous immune resp onses against the. body's own tissues, or against oth er harmless materials, such as food or commensa l organisms. WebDespite the low avidity of these interactions, peripheral tolerance mechanisms are required to prevent spontaneous autoimmunity. Multiple peripheral tolerance mechanisms for myelin-specific T cells have been identified, the most important of which appears to be regulatory T cells.

WebAnergy is likely a more prominent tolerance mechanism that operates in the periphery and is discussed further in that section. These four processes—clonal deletion, clonal diversion, receptor editing, and anergy—are the major mechanisms that limit the self-reactivity of the T-cell repertoire and are crucial for immune health. WebSignificance. Self-tolerance in the B cell compartment of soluble autoantigens depends on mechanisms that promote peripheral B cell elimination. In this study, we report that deficiency in the cysteine protease cathepsin B (Ctsb) in mice results in less efficient removal of chronically antigen-engaged B cells from the repertoire. WebThere are several mechanisms of peripheral tolerance: Anergy: This is a state of functional unresponsiveness that can be induced in T cells or B cells by exposure to antigen in the absence of co-stimulation (a necessary "second signal" for full activation). Without co-stimulation, immune cells may become anergic and unable to respond to ... assa 1956 mässing
