About 90?5 of Gram-negative bacteria are considered to be harmful to their hosts. Many intracellular bacteria, such as, Brucella, Tubercle bacilli, and Salmonella, are pathogenic to both animals and humans and they can be transmitted from animals to humans. These intracellular bacteria are difficult to clear by host immune system and they can cause several syndromes, even death. This is due to inhibit macrophage activity and prevent the formation of phagolysosomes. Infected HIV-RT inhibitor 1 site macrophages can sense the digested product of intracellular bacteria, 1326631 present antigens, and secrete interleukin-12 (IL-12), which promotes differentiation from Th0 to Th1 is impaired. Interferon-gamma (IFN-c) and CD40Lare expressed in Th1 activated macrophages. These induce breath-bursts to kill the intracellular bacteria in the macrophages. Gram-negative bacteria share a similar endotoxin, lipopolysaccharides (LPS), which cause severe syndromes. Large amounts can even cause endotoxemia and septic shock during later stages of infection. Toll-like receptors (TLRs) are a class of type I proteins, playing key roles in innate immune. They detect the invading pathogen and to launch pathogen-killing reaction [1]. TLRs are conserved from drosophila to humans. These receptors are very similar, structurally and functionally. They ZK-36374 web recognize the pathogenassociated molecular patterns (PAMPs) expressed on infectious microbes and mediate the production of cytokines necessary forOverexpression of Toll-Like Receptor 4 in Sheepthe development of effective innate immunity [2]. TLR4, 15755315 which recognizes LPS and initiates a series of intracellular responses, invokes a vigorous cytokine response among immune cells against Gram-negative bacteria [3], TLR4 activates the MyD88- and TRIF-dependent pathways through nuclear factor-kB (NF-kB)?associated signaling events [4?]. It triggers tumor necrosis factor alpha (TNF-a) and it is associated with the activation of the proinflammatory cytokines that cause the inflammatory cascade reaction [6]. TLR4 also acts as a regulator in the immune system. The induction of antigen-presenting cell activation is mediated by acquired immune responses [7]. A mutation in the TLR4 gene was identified in a mouse hyporesponsive to LPS [8]. Bladder epithelial cells of extremely intractable urinary tracts were found to be strongly resistant to infection by most pathogens. These cells selectively exfoliated upon bacterial colonization and underwent re-epithelialization to reduce bacterial load in the bladder. After infection, bladder epithelia secreted large amounts of proinflammatory cytokines, such as IL-6 and chemokine, which are responsible for the vigorous 
neutrophil response and early clearance of infectious bacteria [9,10]. IL-6 mobilizes and amplifies both local and systemic innate immune defenses against infection. It is up-regulated by the acute phase protein [11]. Overexpression of TLR4 in transgenic animals improved the disease resistance accompanying vigorous injury. In transgenic mice with different numbers of copies of TLR4 driven by its natural promoter, overexpression of TLR4 in.X Planck Institute for Biogeochemistry enabled collection of biomass data.
