by Karolinska Institutet Credit: CC0 Public Domain A new study from Karolinska Institutet in Sweden reveals that immune cells in the liver react to high cholesterol levels and eat up excess cholesterol that can otherwise cause damage to arteries. The findings, published in Nature Cardiovascular Research, suggest that the response to the onset of atherosclerosis...

DOI: 10.1038/s41467-024-44861-8A molecule has demonstrated its ability to kill tumor cells and incite an immune response in preclinical models of small cell lung cancer (SCLC), according to UT Southwestern Medical Center researchers. The findings, published in...
by Stanford University Credit: Pixabay/CC0 Public DomainSome cancerous tumors hijack proteins that act as “brakes” on our immune system and use them to form a sort of shield against immune recognition. Immunotherapy treatments have been created that turn off these “brakes” and allow our body to attack foreign-looking cancer cells. To further advance such treatments,...
by Gabriele Meseg-Rutzen, University of Cologne Keeping the immune system in checkModel of RHBDL4-mediated negative feedback regulation of TLR4 signaling. RHBDL4-catalyzed cleavage induces downregulation of TMED7 by the ERAD pathway. Upon loss of RHBDL4, TMED7 accumulates and promotes the trafficking of TLR4 to the cell surface. Consequently, TLR4 downstream signaling is increased, resulting in enhanced...

Upon loss of RHBDL4, TMED7 accumulates and promotes the trafficking of TLR4 to the cell surface. Consequently, TLR4 downstream signaling is increased, resulting in enhanced cytokine secretion. As negative feedback, LPS-induced...

DOI: 10.1136/jitc-2023-008608A new type of immunotherapy that targets non-cancer cells could help prevent the growth and spread of breast cancer tumors, according to new research. The discovery, published 28 February in the Journal for...

Researchers from the Wellcome Sanger Institute, the Olivia Newton-John Cancer Research Institute in Australia, and collaborators have identified specific strains of bacteria that are linked...
by Duke University Medical Center Credit: Pixabay/CC0 Public DomainA perplexing problem for people with recurring urinary tract infections (UTIs) is persistent pain, even after antibiotics have successfully cleared the bacteria. Now Duke Health researchers have identified the likely cause—an overgrowth of nerve cells in the bladder. The finding, appearing March 1 in the journal Science Immunology,...
