Chlamydia pneumoniae is present in the dental plaque of periodontitis patients and stimulates an inflammatory response in gingival epithelial cells

March 11, 2019

This study found that Chlamydia pneumoniae is present more frequently in the dental plaque of individuals with periodontal disease, can invade human gingival epithelial cells causing inflammatory responses, and may therefore be a contributing factor to periodontal disease and a potential indicator of risk.

Insights into the host-pathogen interaction: C. albicans manipulation of macrophage pyroptosis

November 12, 2018

In this article, the authors comment on the study "High-Throughput Screening Identifies Genes Required for Candida albicans Induction of Macrophage Pyroptosis" by O’Meara et al. (MBio, 2018) that provides a comprehensive analysis of the genetic circuitry in both Candida albicans and host macrophages that leads to pyroptosis, revealing the impact of altered pyroptosis on infection, the role of pyroptosis in facilitating neutrophil accumulation at the site of C. albicans infection, and the decoupling of inflammasome priming and activation in the response to C. albicans infection, thus shedding new light on the factors governing the outcomes of this interaction.

Leishmania guyanensis parasites block the activation of the inflammasome by inhibiting maturation of IL-1β

January 14, 2018

The various symptomatic outcomes of cutaneous leishmaniasis relates to the type and potency of its underlying inflammatory responses mediated by Toll-Like-Receptor-3 (TLR3). Here, Hartely et al. investigated other innate pattern recognition receptors capable of reacting to dsRNA and potentially contributing to LRV1-mediated inflammatory pathology. They postulate that avoidance of the inflammasome pathways is likely an important mechanism of virulence in Leishmania infection irrespective of the LRV1-status.
