by Samuel J. White and Philippe B. Wilson, The Conversation Credit: CC0 Public Domain In our fast-paced world, convenience can often come at the cost of nutrition. This shift has led to an increased reliance on ultra-processed foods. But diets high in ultra-processed foods are increasingly being linked to numerous health issues—including obesity, metabolic syndrome...
Immunotherapy could be used to enhance immune responses in older people, making them less vulnerable to infections. News Published: May 16, 2024 | Original story from the University of Minnesota Credit: Congerdesign/ Pixabay Published in Nature Aging, University of Minnesota Medical School researchers provided new insight into enhancing immune responses in older individuals and the...
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...
by Gabriele Meseg-Rutzen, University of Cologne Model 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 cytokine secretion. As negative feedback, LPS-induced...
Researchers are reporting that some early-stage cancer cells activate a gene that helps hide them from the body’s immune response.They say that identifying this uptick in gene expression among cancer cells could lead to new pathways for early diagnosis and future treatment of colon cancer.Experts say more research is needed, however, to confirm these findings...
A new study finds precancerous colon cells turn on a gene called SOX17, which helps them evade detection and develop into more advanced tumors.Peer-Reviewed Publication MASSACHUSETTS INSTITUTE OF TECHNOLOGY CAMBRIDGE, MA — One of the immune system’s primary roles is to detect and kill cells that have acquired cancerous mutations. However, some early-stage cancer cells...
by Cold Spring Harbor Laboratory Graphical abstract. Credit: Molecular Cell (2024). DOI: 10.1016/j.molcel.2024.01.007Our immune system is remarkably powerful. It quickly assembles teams of cells to eliminate threats inside our bodies. But sometimes, it hits the wrong target. Autoimmune diseases like lupus and multiple sclerosis result from friendly fire—immune cells attacking healthy tissues and organs by mistake....
