Research throws light on the mystery of why women are much more prone to autoimmune disorders: A molecule made by one X chromosome in every female cell can generate antibodies to a woman’s own tissues. By Bruce Goldman X chromosomes and autoimmunityIn every cell in a woman’s body, one X chromosome is disabled to ensure...
by German Cancer Research Center Credit: Unsplash/CC0 Public DomainScientists from the German Cancer Research Center (DKFZ) and Heidelberg University have investigated in mice how spreading tumor cells behave at the site of metastasis. Some tumor cells immediately start to form metastases. Others leave the blood vessel and may then enter a long period of dormancy. What...
by European Alliance of Associations for Rheumatology (EULAR) Credit: Unsplash/CC0 Public DomainHemophagocytic lymphohistiocytosis (HLH) and macrophage activation syndrome (MAS) are life-threatening systemic hyperinflammatory syndromes. Systemic hyperinflammation and HLH/MAS can occur in nearly any inflammatory state, but there are certain predisposing conditions and inflammatory triggers. This includes rheumatic diseases, malignancies, metabolic diseases, and genetic immune problems....

This may change in the future. During her Ph.D. research, Sylvia Roovers-Genet examined proteins in the blood of people with, without, and with possible lung cancer, and thereby developed a method...
by Mike Stobbe A Moderna Spikevax COVID-19 vaccine is seen at a drugstore in Cypress, Texas, Sept. 20, 2023. On Thursday, Feb. 1, 2024, the Centers for Disease Control and Prevention said the updated COVID-19 vaccine was 54% effective at preventing symptomatic infection in adults. The shot became available last year as a replacement vaccine...

When advanced glycation end products—a byproduct of poorly controlled diabetes—are added (right), the fibers are shorter and more cross-linked, creating conditions that favor cancer progression.

by Pat Shellenbarger, Michigan State University Model depicting effects of OGM in GBM cells. Lactic acid accumulation from the Warburg effect activates GPR68, which suppresses ATF4 transcription. GPR68 inhibition by OGM induces ATF4 expression, which then increases CHAC1, leading to depletion of glutathione. This ultimately causes accumulation of toxic lipid peroxides, which triggers ferroptosis. Credit: Experimental...
