Comparison of Neutrophil Apoptosis α-Defensins and Calprotectin in Children with and without Severe Early Childhood Caries
Background: The infectious nature of severe early-childhood caries (S-ECC) points to the possible participation of immunologic host responses including neutrophils and their antimicrobial products. Objectives: The aim of this study was to determine the neutrophil apoptosis, α-defensins (HNP1-3) and calprotectin levels in the saliva of preschool children and the association with S-ECC. Methods: ...
متن کاملTherapeutic Potentials of Antimicrobial Peptides
Volume 5 • Issue 3 • 2013 Antimicrobial peptides (AMPs) are small proteins (<100 amino acids) which include alpha-defensins, beta-defensins and the cathelicidin LL-37 in humans [1]. Alpha-defensins are expressed in neutrophils as part of their non-oxidative antimicrobial mechanismsand are also found in Paneth cells in the intestine [2,3]. They are synthesized as precursors that are proteolytica...
متن کاملProduction of beta-defensin antimicrobial peptides by the oral mucosa and salivary glands.
beta-Defensins are cationic peptides with broad-spectrum antimicrobial activity that are produced by epithelia at mucosal surfaces. Two human beta-defensins, HBD-1 and HBD-2, were discovered in 1995 and 1997, respectively. However, little is known about the expression of HBD-1 or HBD-2 in tissues of the oral cavity and whether these proteins are secreted. In this study, we characterized the exp...
متن کاملAssociation of a genetic polymorphism (-44 C/G SNP) in the human DEFB1 gene with expression and inducibility of multiple β-defensins in gingival keratinocytes
BACKGROUND Human beta-defensins (hBDs) are antimicrobial peptides with a role in innate immune defense. Our laboratory previously showed that a single nucleotide polymorphism (SNP) in the 5' untranslated region of the hBD1 gene (DEFB1), denoted -44 (rs1800972), is correlated with protection from oral Candida. Because this SNP alters the putative mRNA structure, we hypothesized that it alters hB...
متن کاملSalivary and serum inflammatory mediators among pre-conception women with periodontal disease
BACKGROUND There have been inconsistent conclusions regarding the levels of inflammatory mediators in saliva and serum among people with or without periodontal disease. Although pre-conception has been put forward as the optimal time for the periodontal treatment in order to improving pregnancy outcomes, few studies have been conducted to examine inflammatory mediators in saliva and serum among...
