    Toll-like receptors and skin
    (WILEY) Ermertcan, AT; Öztürk, F; Gündüz, K
    Toll-like receptors are important pattern recognition receptors which have key roles in both innate and adaptive immune responses. They are strongly associated with the pathogenesis of inflammatory and autoimmune diseases. Furthermore, Toll-like receptors have also been implicated in the pathogenesis of several skin diseases such as skin infections, psoriasis, acne vulgaris, lichen planus, Behcet's disease, leprosy, syphilis, Lyme disease, atopic dermatitis and allergic contact dermatitis, mycosis fungoides, non-melanoma skin cancers and melanoma. In this manuscript, the structure and functions of Toll-like receptors in immune responses, their impact on skin diseases and recent advances on therapeutic usage have been reviewed.

    Impact of hemostatic gene single point mutations in patients with non-diabetic coronary artery disease
    (SPRINGER) Var, A; Ütük, O; Akçali, S; Sanlidag, T; Uyanik, BS; Dinç, G
    Single point mutations in the genes coding for hemostatic factors were shown to be major inherited predisposing factors for venous thromboembolism. However, their contribution in the development of non-diabetic coronary artery disease [nDCAD] remains controversial. Angiographically demonstrated nDCAD patients (n = 86) and healthy controls (n = 90) were included in the study. Genotype analysis of hemostatic gene polymorphisms were assessed by using CVD strip assay, based on allele specific oligonucleotide probes. The carrier frequency of factor V (FV) H1299R, prothrombin G20210A, glycoprotein (Gp) IIIa L33P, plasminogen activator inhibitor-I (PAI-1) 4G/5G, 4G/4G, 5G/5G, methylenetetrahydrofolate reductase (MTHFR) A1298C and beta-fibrinogen -455 G > A were similar between patients and controls. In contrast, frequency of FV Leiden was significantly higher among patients (12.5%) than controls (5%, OR: 7.94; 95%CI: 1.9-49.6) and FXIII V34L was significantly lower among patients (23.7%) than controls (40%, OR: 0.24; 95%CI: 0.1-0.89). In addition, the frequency of the MTHFR C677T polymorphism was 32.5% among patients compared with 42.5% in controls, of which the T/T genotype was significantly lower among patients (5%) than controls (17.5%, OR: 0.06; 95%CI: 0.01-0.58). No difference was observed in prevalence of prothrombin G20210A, FV H1299R, Gp IIIa L33P, PAI-1 4G5G, MTHFR A1298C, beta fibrinogen 455 G > A mutations between patients and controls. However, lower frequency of FXIII Val34Leu and MTHFR C677T polymorphisms may decrease, while FV Leiden polymorphism may increase development of nDCAD.
