The Drosophila antimicrobial response is one of the best characterized systems of pattern recognition receptor-mediated defense in metazoans. Drosophila senses Gram-negative bacteria via two peptidoglycan recognition proteins (PGRPs), membrane-bound PGRP-L ...
Dentritic cells (DC) are the most potent antigen-presenting cells and play a key role in the induction of effective immune responses, suggesting a novel target for anti-tumor immunotherapy. Paclitaxel (PXL) is a widely used chemotherapeutic, initially char ...
Biomarkers are indispensable to the development of new tuberculosis therapeutics and vaccines. The most robust biomarkers measure factors that are essential to the underlying pathological process of the disease being treated, and thus can capture the full ...
New generation vaccines, which are subunit vaccines, have considerably improved safety profiles, but are often poorly immunogenic, especially when administered through mucosal routes. Also, the diversity of the mechanisms of action of infectious pathogens ...
Peptidoglycan is an essential and specific component of the bacterial cell wall and therefore is an ideal recognition signature for the immune system. Peptidoglycan recognition proteins (PGRPs) are conserved from insects to mammals and able to bind PGN (no ...
Spiroplasma poulsonii and its relatives are facultative, vertically transmitted endosymbionts harboured by several Drosophila species. Their long-term survival requires not only evasion of host immunity, but also that Spiroplasma does not have a net detrim ...
Drosophila phagocytes participate in development and immune responses through their abilities to perform phagocytosis and/or secrete extra-cellular matrix components, antimicrobial peptides, clotting factors and signalling molecules. However, our knowledge ...
Mycobacterium tuberculosis (M. tb) the causative agent of tuberculosis (TB) causes 1.7 million deaths annually. According to the World Health Organization, in some areas of the world, 25% of TB cases are due to multi- or extensively drug resistant M. tb st ...
To orchestrate immune responses, pathogen-recognition receptors have evolved sophisticated strategies to monitor pathogenic processes. In this issue of Cell Host & Microbe, a study by Cho et al. reveals a mechanism of immune recognition that relies on the ...
Rationale: Daily rifapentine plus isoniazid-pyrazinamide in mice infected with Mycobacterium tuberculosis produces cure in 3 months. Whether cure corresponds to latent infection contained by host immunity or true tissue sterilization is unknown. ...
