Abstract
Streptococcus pneumoniae, a leading cause of corneal infections worldwide, are extremely aggressive despite antibiotic sensitivity and exhibit increased resistance towards antibiotics. Antimicrobial peptides are often considered as potent alternatives against antibiotic resistance and here we have investigated the possible roles of S100A12, a host defense peptide, in wound healing and S. pneumoniae infection. S100A12 significantly inhibited growth of S. pneumoniae by disruption of membrane integrity along with increased generation of reactive oxygen species. Additionally, S100A12 accelerated cell migration and wound closure in human corneal epithelial cells and in a murine corneal wound model by activation of EGFR and MAPK signaling pathways.
期刊介绍：
Microbes and Infection publishes 10 peer-reviewed issues per year in all fields of infection and immunity, covering the different levels of host-microbe interactions, and in particular:
the molecular biology and cell biology of the crosstalk between hosts (human and model organisms) and microbes (viruses, bacteria, parasites and fungi), including molecular virulence and evasion mechanisms.
the immune response to infection, including pathogenesis and host susceptibility.
emerging human infectious diseases.
systems immunology.
molecular epidemiology/genetics of host pathogen interactions.
microbiota and host "interactions".
vaccine development, including novel strategies and adjuvants.
Clinical studies, accounts of clinical trials and biomarker studies in infectious diseases are within the scope of the journal.
Microbes and Infection publishes articles on human pathogens or pathogens of model systems. However, articles on other microbes can be published if they contribute to our understanding of basic mechanisms of host-pathogen interactions. Purely descriptive and preliminary studies are discouraged.
