Multiple Sclerosis (MS) is an autoimmune disease in which Central Nervous System (CNS) lesions result from perivascular immune cell infiltration associated with damage to myelin, oligodendrocytes and neurons. CNS autoimmunity and its regulation are dominated by the inflammatory cytokines IL17 and IFNγ, and the opposing regulatory cytokines IL10 and the type I IFNs. Toll-like receptors (TLR) pla...

Humoral immunity to viruses and encapsulated bacteria is comprised of T cell-independent type 2 (TI-2) antibody responses that are characterized by rapid antibody production by marginal zone and B1 B cells. We demonstrate that toll-like receptor (TLR) ligands influence the TI-2 antibody response not only by enhancing the overall magnitude but also by skewing this response to one that is dominat...

INTRODUCTION Toll-like receptors (TLRs) are an important link between innate and adaptive immunity. MATERIAL AND METHODS Expression of TLR-2, TLR-4, and TLR-9 genes was assessed in 60 coronary artery disease (CAD) patients and 79 controls by SYBR Green 1 based real time PCR assay. RESULTS Expression of the TLR-2 gene was found to be significantly elevated in cases (1.295 ±0.09) compared to ...

Here, we have investigated the mRNA expression of Toll-like receptor 2 (TLR-2), TLR-4, and MD-2 in spleens and livers of C3H/HeN mice (carrying wild-type TLR-4) and C3H/HeJ mice (carrying mutated TLR-4) in response to Salmonella infection. During Salmonella infections, TLR-4 is activated, leading to increased TLR-2 and decreased TLR-4 expression.

INTRODUCTION Plasmacytoid dendritic cells (pDCs) constitutively express two members of the Toll-like receptor (TLR) family, TLR-9 and TLR-7, through which they can be stimulated to produce high levels of interferon (IFN)-α, a key mediator of the pathogenesis of systemic lupus erythematosus (SLE). Given the known efficacy of hydroxychloroquine (HCQ) in the treatment of SLE, we examined its abili...

I use the first-time enforcement of insider trading laws in sixteen countries as a shock to enforcement and examine its influence on timely loss recognition (TLR). Consistent with greater enforcement increasing the usefulness of accounting information in contracts and thereby the demand for higher quality reporting, insider trading enforcement is associated with a significant increase in TLR. N...

OBJECTIVE Immune and inflammatory signaling pathways, initiated by the innate response, are involved in myocardial ischemia/reperfusion (I/R) injury. Toll-like receptor (TLR) mediated MyD88-dependent NFkappaB pathways play a role in the induction of innate immunity. We have reported that glucan phosphate (GP) improved survival in experimental sepsis, which correlated with decreased tissue NFkap...
