A study published in Neuron found that the abnormal HD protein selectively binds to and increases the level of p53 in cells, leading to increased cell death and mitochondrial dysfunction. This overactivation also causes behavioral abnormalities in mice engineered to have HD.
Scientists at Salk Institute created a mouse model to study p53 regulation in vivo, finding that chemical modifications are not essential for protein activation under stress or normal conditions. The research has implications for cancer treatment and the development of specific drugs targeting p53's negative regulators.
Researchers have identified the compound allicin as responsible for activating specific protein thermoreceptors in the mouth, leading to the characteristic burning sensation of raw garlic. This finding provides new insights into the pungency associated with raw garlic and its potential health benefits.
Researchers found that chemokines CCL19 and CCL21 induce DC maturation and enhance T-cell proliferation. Mice lacking these chemokines showed partially activated DCs, highlighting their crucial role in full maturation and proper T-cell activation.
A study published in Science identified interleukin-1Beta (IL-1â) as a major cause of severe inflammation in mouse models of Crohn's disease, which is a chronic inflammatory bowel disease affecting over 500,000 Americans. High levels of IL-1â were found in mice with mutant NOD2, a genetic defect linked to 50% of Crohn's cases.
Researchers found that Alpha-4Beta-1 is activated by CD47, causing sickle red blood cells to stick to blood vessel walls. This discovery may lead to new therapies for sickle cell disease and other anemias.
Researchers have developed a new dye that allows for direct visualization of activated proteins in living cells, enabling high-throughput drug screening.
