Single nucleotide polymorphisms of TLR-2, TLR-3, TLR-4 and susceptibility to inflammatory diseases of the respiratory tract

Functional Toll-Like Receptor (TLR)2 polymorphisms in the susceptibility to inflammatory bowel disease

BACKGROUND The recent genome-wide association studies (GWAS) in inflammatory bowel disease (IBD) suggest significant genetic overlap with complex mycobacterial diseases like tuberculosis or leprosy. TLR variants have previously been linked to susceptibility for mycobacterial diseases. Here we investigated the contribution to IBD risk of two TLR2 polymorphisms, the low-prevalence variant Arg753G...

بررسی تأثیر ابتلا به پریودنتیت مزمن بر میزان بیان ژن TLR-2 و TLR-4 در بافت لثه ای

مقدمه: در عفونت‏های پریودنتال پیش نیاز شروع پاسخ‏های میزبان، شناخت پاتوژن‏‏ها توسط سیستم ایمنی میزبان می‏باشد. خانواده رسپتور‏های Toll-like (TLRs)، مسئول شناسایی ساختار‏های حفظ شده میکروبیال نظیر لیپوپلی ساکارید (LPS) باکتری‏ها می‏باشند و مسیر‏های سیگنال دهنده را که در نهایت منجر به پاسخ‏های ایمنی می‏شود، فعال می‏کنند. هدف از مطالعة حاضر، ارزیابی مقایسه میزان بروز TLR-2 و TLR-4 توسط تکنیک Real-...

Toll-like receptor (TLR) polymorphisms in African children: common TLR-4 variants predispose to severe malaria.

Genetic host factors play a substantial role in susceptibility to and severity of malaria, which continues to cause at least one million deaths per year. Recently, members of the toll-like receptor (TLR) family have been shown to be involved in recognition of the etiologic organism Plasmodium falciparum: The glycosylphosphatidylinisitol anchor induces signaling in host cells via TLR-2 and -4, w...

TLR-2 and TLR-4 expression in monocytes of newborns with late-onset sepsis.

OBJECTIVE To analyze toll-like receptor (TLR)-2 and TLR-4 expression in monocytes of newborns with late-onset sepsis. METHODS This prospective study included 27 full-term newborns aged 8 to 29 days, with clinical and laboratory diagnosis of late-onset sepsis. Ten newborns (37%) had positive cultures. Cytokines were measured by cytometric bead array in peripheral blood, while TLR-2, TLR-4 expr...
