Bacterial Immunity and Host Defense
001 Abstract Microbes are the key players for deteriorating the host defense. They enter inside the host system, colonize the host cells, evade the host immunity and ultimately leads to tissue injury and ultimately disease. But the body cells are having strong immune system to combat with these aliens. There are two basic types of immune responses in body for bacterial degradation. Immune respo...
متن کاملPulmonary host defense mechanisms.
T he major function of the respiratory system is to procure oxygen from the external environment and to eliminate carbon dioxide from the body at rates required by tissue metabolism. Unfortunately, ambient inspired air contains not only oxygen which is vital to survival, but also noxious gases and a multitude of particulates, including viable microorganisms, which the lungs must exclude to main...
متن کاملTranscript analysis of some defense genes of tomato in response to host and non-host bacterial pathogens
The transcript levels of six defense genes including pathogenesis-related gene 1 (PR-1), pathogenesis-related gene 2 (PR-2), pathogenesis-related gene 5 (PR-5), lipoxygenase (LOX), phenylalanine ammonia-lyase (PAL) and catalase (CAT) were investigated in tomato plants inoculated with Xanthomonas axonopodis pv. phaseoli as a non-host pathogen and X. euvesicatoria as a host pathogen. Activation o...
متن کاملZinc: mechanisms of host defense.
Zinc deficiency in humans decreases the activity of serum thymulin (a thymic hormone), which is required for maturation of T-helper cells. T-helper 1 (Th(1)) cytokines are decreased but T-helper 2 (Th(2)) cytokines are not affected by zinc deficiency in humans. This shift of Th(1) to Th(2) function results in cell-mediated immune dysfunction. Because IL-2 production (Th(1) cytokine) is decrease...
متن کاملSubversion of host defense mechanisms by murine tumors. II. Counter- influence of concomitant antitumor immunity
Subcutaneous injection of murine tumor cells first resulted in a state of severely suppressed macrophage-mediated antibacterial resistance and then in a contrasting state of greatly enhanced antibacterial resistance. Whereas, the state of suppressed antibacterial resistance corresponded to a state of suppressed resistance to a tumor cell challenge, the generation of enhanced antibacterial resis...
