Protease shaving of facilitates vaccine antigen discovery and delivery of novel cargoes to the Mtb surface.

Tuberculosis (TB) is the leading cause of infectious disease death and lacks a vaccine capable of protecting adults from pulmonary TB. The bacterial surface is a critical interface that shapes host-pathogen interactions. Several knowledge gaps persist in our understanding of (Mtb)-host interactions that may be addressed by an improved understanding of the Mtb surface proteome, including the identification of novel vaccine targets as well as developing new approaches to interrogate host-pathogen interactions.

Protease shaving of facilitates vaccine antigen discovery and delivery of novel cargoes to the Mtb surface.

Tuberculosis (TB), caused by (Mtb), is the leading cause of infectious disease death and lacks a vaccine capable of protecting adults from pulmonary TB. Studies have shown that Mtb uses a variety of mechanisms to evade host immunity. Secreted Mtb proteins such as Type VII secretion system substrates have been characterized for their ability to modulate anti-Mtb immunity; however, studies of other pathogens such as Typhi and have revealed that outer membrane proteins can also interact with the innate and adaptive immune system.

Single-cell analysis reveals a weak macrophage subpopulation response to Mycobacterium tuberculosis infection.

Mycobacterium tuberculosis (Mtb) infection remains one of society's greatest human health challenges. Macrophages integrate multiple signals derived from ontogeny, infection, and the environment. This integration proceeds heterogeneously during infection.

TLR2 is non-redundant in the population and subpopulation responses to in macrophages and .

Tuberculosis (TB), caused by the pathogenic bacterium (Mtb), is a global health threat. Targeting host pathways that modulate protective or harmful components of inflammation has been proposed as a therapeutic strategy that could aid sterilization or mitigate TB-associated permanent tissue damage. In purified form, many Mtb components can activate innate immune pathways.

The Effect of Doulas on Maternal and Birth Outcomes: A Scoping Review.

A source of support during birth could be the solution to negative outcomes for the mother and her baby. To improve the birthing experience and increase positive birthing outcomes, sources of support during pregnancy should be evaluated and understood. The goal of this review was to synthesize the existing literature on how doulas might improve birth outcomes.

Flow Cytometry Analysis of Mycobacteria and Mycobacteria-Infected Immune Cells.

Flow cytometry enables the measurement of tens of features on individual cells from complex mixtures. Flow cytometry enables high-throughput quantification of cell size, gene and protein expression. In the case of studies of host-pathogen interactions, this tool provides a facile way of identifying cells that have been successfully infected by a pathogen.

Uncovering complex molecular networks in host-pathogen interactions using systems biology.

Interactions between pathogens and their hosts can induce complex changes in both host and pathogen states to privilege pathogen survival or host clearance of the pathogen. To determine the consequences of specific host-pathogen interactions, a variety of techniques in microbiology, cell biology, and immunology are available to researchers. Systems biology that enables unbiased measurements of transcriptomes, proteomes, and other biomolecules has become increasingly common in the study of host-pathogen interactions.
