In the battle against infections with mycobacteria, the body employs components of both the innate and adaptive arms of the immune system. Toll-like receptors (TLRs) mediate the activation of cells of the innate immune system leading to dynamic functions including direct anti-microbial activity, induction of cytokine secretion, triggering dendritic cell maturation, and triggering apoptosis. Fur...

H9N2 influenza virus is endemic in many Asian countries and is regarded as a candidate for the next human pandemic. Knowledge of the induction of inflammatory responses and toll-like receptors (TLRs) in chickens infected with H9N2 is limited. Here, we show that H9N2 induces pro-inflammatory cytokines such as transforming growth factor-beta 3; tumor necrosis factor-alpha; interferon-alpha, -beta...

Toll-like receptors (TLRs) have been identified as central innate immune receptors. They distinguish among different patterns of pathogens and rapidly activate an innate immune response. However, TLRs can also be stimulated by host-derived molecules. They are expressed in the cardiovascular system and could thus be a key link between cardiovascular diseases and the activation of the immune syst...

Toll-like receptors (TLRs) signal the presence of pathogens and tissue injury, triggering the inflammatory process in macrophages. The goal of inflammation is to resolve the injury and return the body to homeostasis. MicroRNAs are an important group of regulators of TLR signaling and several are induced by TLRs in macrophages. These TLR-induced microRNAs target signaling components in the TLR p...

Toll-like receptors (TLRs) are crucial components of innate immunity that specifically recognize diverse pathogen-associated molecular patterns from pathogens. The continuous hydrogen-bond network (asparagine ladder) formed among the asparagine residues on the concave surfaces of neighboring leucine-rich repeat modules assists in stabilizing the overall shape of TLR ectodomains responsible for ...

Toll-like receptors (TLRs) are pattern recognition receptors that trigger innate immunity. In this study we investigated the expression of 10 TLRs in human naive and memory B-cell subsets. We report that in human naive B cells most TLRs are expressed at low to undetectable levels, but the expression of TLR9 and TLR10 is rapidly induced following B-cell-receptor (BCR) triggering. In contrast, me...

Facial nerve palsy directly impacts the quality of life, with patients facial showing increased rates depression and limitations in social activities. Although is not life-threatening, it can devastate emotional lives affected individuals. Hence, improving prognosis this condition vital importance. The determined by cause disease, degree damage, treatment provided. be easily damaged middle ear ...

Toll-like receptors (TLRs) are an essential component of innate immunity, the first line of defense against invading pathogens. However, in addition to activating antimicrobial effector responses directly, TLRs lead to the induction of signals that control the activation of adaptive responses including autoimmune responses and allorecognition. This ability of TLR to control both innate and adap...

The past 10 years have seen the description of families of receptors that drive proinflammatory cytokine production in infection and tissue injury. Two major classes have been examined in the context of inflammatory joint disease--the Toll-like receptors (TLRs) and NOD-like receptors (NLRs). TLRs such as TLR2 and TLR4 are being implicated in the pathology of rheumatoid arthritis, ankylosing spo...

Toll-like receptors (TLRs) play a key role in the innate immune response to invading pathogens. Thus, their discovery has opened up a wide range of therapeutic possibilities for various infectious and inflammatory diseases. In the last several years, extensive research efforts have provided a considerable wealth of information on the expression and function of TLRs in the eye, with significant ...
