Clinical Biochemistry, 1983
Information is presented on changes in the aging immune system. An analysis of separate streams of cellular aging in the inbred mouse is presented. It is demonstrated that there is extensive polymorphism in the aging of different types of executive and regulatory cell lines.

The immune system in the elderly
Immunologic Research, 1999The capability to cope with infectious agents and cancer cells resides not only in adaptive immune responses against specific antigens, mediated by T and B lymphocytes clonally distributed, but also in natural immune reactions. These innate defence mechanisms include chemotaxis, phagocytosis, natural cytotoxicity, cell interactions, and soluble ...

The liver regulates T-cell homeostasis, induces T-cell tolerance, and supports intrahepatic T-cell responses against hepatotropic pathogens. Many data from clinical and preclinical systems provide supportive evidence for these diverse roles of the liver in modulating peripheral (systemic, mucosal, and intrahepatic) T-cell immunity.

Tumor exists as a complex network of structures with an ability to evolve and evade the host immune surveillance mechanism. The immune milieu which includes macrophages, dendritic cells, natural killer cells, neutrophils, mast cells, B cells, and T cells is found in the core, the invasive margin, or the adjacent stromal or lymphoid component of the ...

The immune system and the nervous system
Journal of Neurology, 1983The immune system may interfere with brain function. The central nervous system may also influence the activity of the immune system. The central nervous system is functionally protected by the blood-brain barrier. The central nervous system is functionally protected by the blood-brain barrier.

Tachykinins in the Immune System
Current Drug Targets, 2006Until recently, the mammalian tachykinins included substance P, neurokinin A and neurokinin B. Following the discovery of the fourth member of this family, hemokinin 1, a diverse group of novel tachykinins and tachykinin gene-related peptides have been identified in mammals.

The immune memory of innate immune systems
International ImmunologyAbstract Immune memory has long been considered a function specific to adaptive immune systems; however, adaptive immune memory alone has not fully explained the mechanism by which vaccines exert their protective effects against nontarget pathogens.

Tolerance and Immunity in the Intestinal Immune System
Critical Reviews™ in Immunology, 2000The intestinal immune system must guard the body against invasion by pathogens while avoiding a response to the many potential antigens present in food. In the absence of the inflammatory stimuli necessary to elicit an immune response, oral administration of soluble protein antigens induces antigen-specific systemic nonresponsiveness.

Amplification Systems in Immunity
Scottish Medical Journal, 1974The role of chemical messengers is considered in relation to the initiation and amplification of the immune response. The roles of pre-existing tissue factors of the complement, clotting and Kinin systems, are considered and the additional effects of the chemical mediators produced by activated lymphocytes and tissue breakdown products are described.

Immunization Information Systems
Journal of Public Health Management and Practice, 2014s. Another Community Guide systematic review, “Economic Review of Immunization Information Systems to Increase Vaccination Rates,” evaluated the costs and benefits associated with using these systems. IIS require funding for implementing and operating the system and providers and the IIS incur costs for data exchange.
