Bacterial battle in 3D

Jun. 2, 2022—Using imaging mass spectrometry and microscopy, Vanderbilt researchers visualized how staph bacteria modifies lipids in its membrane to evade immune system-mediated killing.

Youthful healing for burn wounds

Apr. 21, 2022—Topical treatment of burns with an immunosuppressive drug counteracted the negative effects of aging on wound healing, Vanderbilt researchers have discovered.

Study finds 10-second videos predict blood cancer relapse

Mar. 28, 2022—Vanderbilt research shows that 10-second videos of white blood cell motion in the skin’s microvasculature greatly improved the prediction of which stem cell and bone marrow transplant patients would have a relapse of their blood cancer.

Blood test figures in cancer risk for people with HIV

Mar. 17, 2022—A Vanderbilt study found that, among adult patients with HIV, those who have lower counts of certain types of blood cells have a markedly higher risk of developing cancer.

Who’s who in the respiratory landscape

Nov. 15, 2021—A metatranscriptomics method developed by Vanderbilt researchers simultaneously characterizes viruses, microbiome and host response in nasal swabs, opening opportunities to explore molecular interactions directly in clinical samples.

‘Pre-conditioning’ restores immune tolerance

Sep. 16, 2021—A treatment targeting T-cell metabolism could reinvigorate immune tolerance mechanisms to combat autoimmune disease and transplant rejection, Vanderbilt researchers discovered.

Autoimmunity advance

Aug. 24, 2021—Vanderbilt researchers have developed a high-throughput screening method to identify and characterize antigen-specific B cells — potential biomarkers for autoimmune disease and targets for new treatments.

The team studying the regulation of innate immune response includes (front row, from left) Yang Zhao, Antiana Richardson, (back row, from left) John Karijolich, PhD, Xiang Ye and William Dunker.

Study finds that regulatory protein prevents signaling that triggers cell death

May. 6, 2021—A protein implicated in neurodegenerative diseases including amyotrophic lateral sclerosis prevents the activation of an innate immune response that leads to cell death, Vanderbilt researchers have discovered.

Allison Norlander, PhD, R. Stokes Peebles, MD, and colleagues are studying an approved drug that enhances immune cells and might be useful for treating inflammatory and autoimmune diseases.

Team studies new use for pulmonary hypertension drug

Mar. 25, 2021—An FDA-approved medication enhances the function of T regulatory cells (Treg), a class of immune cells that restrains the immune response, Vanderbilt investigators have discovered.

HIV, diabetes and immune cells in fat

Mar. 18, 2021—In HIV-positive individuals with diabetes, immune cells in fat are more proinflammatory and cytotoxic and may represent a therapeutic target for diabetes.

Ann Richmond, MD, Chi Yan, PhD, Jinming Yang, PhD, and colleagues are studying ways to boost antitumor immunity and reduce tumor growth in breast cancer and melanoma.

Study reveals new strategy for reducing tumor growth, metastasis

Dec. 17, 2020—A team of Vanderbilt investigators has discovered that blocking a certain signaling pathway boosts antitumor immunity and reduces tumor growth and metastasis in models of breast cancer and melanoma.
