The controlled cell death process of apoptosis functions as the first step to any full recovery from injury or disease. In the second step of any recovery process, dead cells are cleared by efferocytosis, a process performed by phagocytotic cells like macrophages. Approximately 200-300 billion apoptotic cells are cleared daily by efferocytosis starting with the recognition of newly extracellular facing phosphatidylserine (PtdSer) by PtdSer-binding proteins present on phagocytotic cells.
Korean Research Institute of Bioscience and Biotechnology has described triterpenoid saponins isolated from Spinacia oleracea (spinach) reported to be useful for the treatment of inflammation.
The first in vivo cell atlas of senescent tissue in skeletal muscle has identified the damaging properties of these cells and explained why they block muscle regeneration. According to a study at Pompeu Fabra University led by scientists from Altos Labs Inc., cell damage caused the senescence of the cells, which secreted toxic substances into the surrounding microenvironment, causing fibrosis and preventing tissue regeneration.
Innovent Biologics Inc. has in-licensed LG Chem Ltd.’s tigulixostat (LC-350189), a late-stage non-purine xanthine oxidase inhibitor for managing chronic hyperuricemia in patients with gout, in a deal worth up to $95 million.
Pharmablock Sciences (Nanjing) Inc. has divulged non-receptor tyrosine-protein kinase TYK2 inhibitors reported to be useful for the treatment of inflammation and autoimmune disease.
Unlike amphibians, mammals do not regenerate appendages. Except when they do. “If you amputate one of the branches off of the antler [of a reindeer], it will also regenerate,” Jeff Biernaskie told BioWorld. Even without amputation, the antlers of both male and female reindeer regenerate annually, including their skin. That regeneration is “the only large mammal model of true skin regeneration,” he said.
Liver damage arrests growth mediated by the somatotroph axis, which prevents liver cell death and inflammation, but increases fibrosis in nonalcoholic fatty liver disease (NAFLD). The explanation for this effect could lie in the relationship between the activating transcription factor 3 (ATF-3) and insulin-like growth factor 1 (IGF-1), according to a study from the University of California at Berkeley.
Apogee Therapeutics Inc. emerged from stealth with $169 million in financing and a pipeline of four preclinical antibody development programs that take aim at major immunological and inflammatory disorders.
The age-old separation of dentistry from medicine is deeply embedded in education and professional practice. Given the great advances in both disciplines in recent decades, there is a reasonable argument to be made for maintaining the divide.
Retrotransposons could have a main role in the development of drug resistance in response to cancer treatment, according to a new study out of the Roswell Park Comprehensive Cancer Center. The transposition of DNA elements triggers an inflammatory response involved in the survival of cancer cells, a mechanism that could be blocked applying reverse transcriptase inhibitors, a class of drugs better known as anti-HIV medications.
