HIV, diabetes and immune cells in fat

In HIV-positive individuals with diabetes, immune cells in fat are more proinflammatory and cytotoxic and may represent a therapeutic target for diabetes.

Key factors in HIV-1 replication

HIV-1, the virus that causes AIDS, exploits inositol phosphates in T cells to aid its own assembly and maturation — suggesting that targeting inositol phosphate binding could inhibit HIV-1 replication.

Probing pathogen antibiotic resistance

Understanding how bacteria evolve resistance to antibiotics and host stresses could guide the development of more effective antimicrobial therapeutics.

C. diff captures blood cell cofactor to build defensive shield

Vanderbilt University Medical Center scientists have identified a C. diff protein system that senses and captures heme (part of hemoglobin) to build a protective shield that fends off threats from our immune system and antibiotics.

Jim Cassat, MD, PhD, and colleagues are studying enzymes involved in metabolism that are particularly important for Staphylococcus aureus to survive in host tissues.

Study explores how staph bacteria can survive in bone

A comprehensive evaluation of the metabolic pathways that support Staphylococcus aureus (“staph”) growth during invasive bone infections could offer new targets for treatment.

The adaptable anthrax bacterium

Vanderbilt researchers discover how anthrax bacterium defends itself against structural damage and resists the toxicity of the antimicrobial drug targocil.
