Near–infrared photodynamic inactivation of S. pneumoniae and its interaction with RAW 264.7 macrophages
(2018-01-01)
Pneumonia is the main cause of children mortality worldwide, and its major treatment obstacle stems from the microorganisms increasing development of resistance to several antibiotics. Photodynamic therapy has been presenting, ...
Curcuma longa L. helps macrophages to control opportunistic micro-organisms during host-microbe interactions
(2020-09-01)
Aim: Plant products have been evaluated to control opportunistic micro-organisms, as well as fortify immune system cells. Thus, Curcuma longa L. (turmeric) extract was evaluated in interactions of murine macrophages (RAW ...
Stg fimbrial operon from S. Typhi STH2370 contributes to association and cell disruption of epithelial and macrophage-like cells
(Sociedad de Biología de Chile, 2015)
BACKGROUND: Salmonella enterica serovar Typhi (S. Typhi) stg operon, encoding a chaperone/usher fimbria (CU), contributes to an increased adherence to human epithelial cells. However, one report suggests that the presence ...
Productive infection of Piscirickettsia salmonis in macrophages and monocyte-like cells from rainbow trout, a possible survival strategy
(2009)
Piscirickettsia salmonis is the etiologic agent of the salmonid rickettsial septicemia (SRS), an endemic disease which causes significant losses
in salmon production. This intracellular bacterium is normally cultured in ...
Bordetella parapertussis Survives inside Human Macrophages in Lipid Raft-Enriched Phagosomes
(American Society for Microbiology, 2014-08)
Bordetella parapertussis is a human pathogen that causes whooping cough. The increasing incidence of B. parapertussis has been attributed to the lack of cross protection induced by pertussis vaccines. It was previously ...
The scavenger receptor MARCO is involved in Leishmania major infection by CBA/J macrophages
(2009)
CBA/J mice are resistant to Leishmania major infection but are permissive to L. amazonensis infection. In addition, CBA/J macrophages control L. major but not L. amazonensis infection in vitro. Phagocytosis by macrophages ...
Role of NOD2 and RIP2 in host-microbe interactions with Gram-negative bacteria: Insights from the periodontal disease model
(2016-11-01)
NOD2 is a member of the NLR family of proteins that participate in the activation of the innate immune response. RIP2 is a downstream kinase activated by both NOD1 and NOD2. There is scarcity of information regarding the ...
The small rna ryhb homologs from salmonella typhimurium restrain the intracellular growth and modulate the spi-1 gene expression within raw264.7 macrophages
(MDPI AG, 2021-03)
Growing evidence indicates that small noncoding RNAs (sRNAs) play important regulatory roles during bacterial infection. In Salmonella Typhimurium, several sRNAs are strongly up-regulated within macrophages, but little is ...
