Abstract
In this comparative study, serum complement system antimicrobial activity was measured from 159 serum samples, taken from individuals from microbe-damaged (70 samples) and from reference buildings (89 samples). Antimicrobial activity was assessed using a probe-based bacterial Escherichia coli-lux bioluminescence system and comparison was made at a group level between the experimental and reference group. The complement activity was higher in users of microbe-damaged buildings compared with the reference group and the significant (P < 0.001) increase in activity was found in the classical reaction pathway. This study strengthens our notion that exposure to indoor-related microbe damage increases the risk for systemic subclinical inflammation and creates a health risk for building users.
期刊介绍:
Innate Immunity is a highly ranked, peer-reviewed scholarly journal and is the official journal of the International Endotoxin & Innate Immunity Society (IEIIS). The journal welcomes manuscripts from researchers actively working on all aspects of innate immunity including biologically active bacterial, viral, fungal, parasitic, and plant components, as well as relevant cells, their receptors, signaling pathways, and induced mediators. The aim of the Journal is to provide a single, interdisciplinary forum for the dissemination of new information on innate immunity in humans, animals, and plants to researchers. The Journal creates a vehicle for the publication of articles encompassing all areas of research, basic, applied, and clinical. The subject areas of interest include, but are not limited to, research in biochemistry, biophysics, cell biology, chemistry, clinical medicine, immunology, infectious disease, microbiology, molecular biology, and pharmacology.
