BACKGROUND Myeloid differentiation factor 88 (MyD88) is an endogenous adaptor protein that coordinates the inflammatory response to agonists of the Toll-like receptor and interleukin-1 receptor families. This particular response is activated following myocardial ischemia and infarction and may represent a viable target for pharmacologic inhibition. The current study tested MyD88 inhibitors in a...
MyD88 is a common Toll-like receptor (TLR) adaptor molecule found to be essential for induction of adaptive Th1 immunity. Conversely, innate control of adaptive Th2 immunity has been shown to occur in a MyD88-independent manner. In this study, we show that MyD88 is an essential innate component in the induction of TLR4-dependent Th2 responses to intranasal antigen; thus we demonstrate what we b...
MyD88 KO (knockout) mice are exquisitely sensitive to CNS (central nervous system) infection with Staphylococcus aureus, a common aetiological agent of brain abscess, exhibiting global defects in innate immunity and exacerbated tissue damage. However, since brain abscesses are typified by the involvement of both activated CNS-resident and infiltrating immune cells, in our previous studies it ha...
The MYD88 L265P somatic variant (MYD88) has a high prevalence in Waldenstrom's Macroglobulinemia (WM), a form of lymphoplasmacytic lymphoma (LPL) associated with monoclonal IgM. Although the role of MYD88 in WM was initially reported in 2012, it was not until 2016 that MYD88 testing was included in the National Cancer Care Network (NCCN) Guidelines. We present a case illustrating the utility of...
MyD88 and TRIF mediate divergent inflammatory and regenerative responses to skeletal muscle ischemia
We have previously shown that MyD88 KO mice appear protected from ischemic muscle injury while TRIF KO mice exhibit sustained necrosis after femoral artery ligation (FAL). However, our previous data did not differentiate whether the protective effect of absent MyD88 signaling was secondary to attenuated injury after FAL or quicker recovery from the insult. The purpose of this study was to delin...
The development of vaccine adjuvants is interest for the management chronic diseases, cancer, and future pandemics. Therefore, role Toll-like receptors (TLRs) in effects has been investigated. TLR4 ligand-based are most frequently used human vaccines. Among TLR family members, unique dual signaling capabilities due to recruitment two adapter proteins, myeloid differentiation marker 88 (MyD88) i...
Background and objectives: TLR2, TLR4, and Dectin-1 (Clec7) are pattern recognition receptors (PRRs) expressed by intestinal epithelia cells and MYD88 is a signaling molecule of TLR2 and TLR4. They warn immune system about the presence of invading pathogens promoting initiation of inflammatory response. Because of colonic cancer risk, therapy of intestinal inflammation is of h...
OBJECTIVE To evaluate myeloid differentiation primary response gene 88 (MyD88) and Toll-like receptor 4 (TLR4) expression in relation to clinical features of epithelial ovarian cancer, histologic subtypes, and overall survival. PATIENTS AND METHODS We conducted centralized immunohistochemical staining, semi-quantitative scoring, and survival analysis in 5263 patients participating in the Ovar...
Listeria monocytogenes is a food-borne bacterial pathogen that causes systemic infection by traversing the intestinal mucosa. Although MyD88-mediated signals are essential for defense against systemic L. monocytogenes infection, the role of Toll-like receptor and MyD88 signaling in intestinal immunity against this pathogen has not been defined. We show that clearance of L. monocytogenes from th...
The efficacy of T cell-based immunotherapy to treat cancer patients remains a challenge partly because of the weak activity toward subdominant tumor antigens (TAg) and to tumors expressing suboptimal TAg levels. Recent reports indicate that Toll-like receptor (TLR) stimulation on T cells can lower the activation threshold. In this study, we examined the antitumor activity and survival of TLR2-M...
