A new study has found that the immune remodeling associated with fasting can be recapitulated by activating a subset of neurons in the hypothalamus. The findings could be important in the context of fasting mimicking, metabolic disorders, and cancer [1]. Fasting and the immune system Decades after the modern field of geroscience was born, caloric...

Researchers have improved multiple health metrics in prematurely aged mice by re-establishing the production of neuropeptide Y in the hypothalamus [1]. An essential protein Age-related decline in the function of the hypothalamus, a core region of the brain, has been suggested to be a “key factor in the development of whole-body aging” [2]. Due to...

Yesterday in Aging Cell, researchers published their findings that using gene therapy to overexpress a synaptic promoter increases cognitive ability in ordinary, middle-aged mice. Hevin vs. SPARC Astrocytes are general-purpose helper cells of the brain, and one of their tasks is to maintain synapse structure [1]. They secrete synapse-modifying molecules, including members of the SPARC...

Researchers have devised a method of reducing brain inflammation by creating a long-lasting inhibitor of the inflammatory factor NF-κB. Targeting inflammaging at its roots This study, published in the Nature journal Experimental & Molecular Medicine, begins with a discussion of age-related chronic inflammation (inflammaging) and its contributions to aging. Specifically, the researchers focus on neuroinflammation,...

In Aging Cell, researchers have identified a receptor in the brain that appears to be responsible for cognitive problems after surgery, particularly in older people. Surgery can cause cognitive problems Neurological symptoms such as postoperative cognitive dysfunction [1] and postoperative delirium [2] are common after surgery, particularly when the surgery is intensive or the patient...

Neurological researchers, in Aging Cell, have deepened our understanding of the brain, explaining how turning off a dopamine receptor may lead to better memory in older people. Sometimes it's better for the dopamine not to hit With aging comes changes in how the brain processes dopamine [1]. This work focuses on specific dopamine receptors called...
