Insights

Salmonellae bacteria cause illness, and macrophages are key immune cells. Studying their interaction reveals insights into infection and cellular microbiology, with future research focusing on cell variability.

Area of Science:

  • Immunology
  • Microbiology
  • Cellular Biology

Background:

  • Salmonellae are significant enteric pathogens responsible for gastroenteritis and systemic diseases.
  • Macrophages are crucial immune cells involved in both innate and adaptive immunity, exhibiting phagocytic and antigen-presenting functions.

Observation:

  • The interaction between Salmonellae and macrophages serves as a foundational model for studying infection dynamics and cellular microbiology.
  • Primary macrophages can be cultured from various sources, facilitating research into bacterial survival and host-pathogen interactions.

Findings:

  • Historical research using Salmonellae-macrophage models has yielded significant discoveries in understanding host-pathogen interactions.
  • Future research directions include exploring bacterial and macrophage cell variability and its impact on infection outcomes.

Implications:

  • Understanding Salmonellae-macrophage interactions is vital for developing strategies against enteric infections.
  • Investigating cellular heterogeneity offers new perspectives on the complexities of infectious disease progression.

An Assay to Quantify Cytosolic and Vacuolar Salmonella in Infected Primary Macrophages

This video demonstrates an assay to quantify cytosolic and vacuolar Salmonella typhimurium inside bone marrow-derived macrophages using differential permeabilization. The macrophages are infected with a fluorescent protein-expressing Salmonella, which is internalized inside a specialized vacuolar structure called Salmonella-containing vacuole or SCV. A subset of bacteria escape the SCV and enter the cytosol. The cholesterol-rich plasma membrane of macrophages is permeabilized using digitonin,...

Automated Analysis of Intracellular Phenotypes of Salmonella Using ImageJ

Salmonella invades and replicates inside intestinal epithelial cells both in Salmonella-specific vacuoles and free in the cytosol (hyper-replication). A high-throughput fluorescence microscopy-based protocol is described here to quantify the intracellular phenotypes of Salmonella by two complementary image analyses through ImageJ, reaching single-cell resolution and...
