A new study calls for caution in using the well-known senolytic treatment of dasatinib and quercetin (D+Q), showing that it causes damage in certain regions of the brain, similar to what is observed in multiple sclerosis [1]. Stem cell senescence prevents brain repair Multiple sclerosis (MS) is a brain disorder in which the patient’s own...
Obese mouse and healthy mouse
A new study has suggested that T cells might retain a pro-inflammatory phenotype long after normal weight is regained following a period of obesity. In mice, the effect lasts for weeks, while its existence and duration in humans are to be determined [1]. The inflammation that stays Obesity is a chronic, relapsing condition linked to...
Wound healing
A team of scientists has examined how younger and older mice heal from wounds and found that more robust senescent cell activation in younger animals helps them heal faster. A double-edged sword Cellular SenescenceAs your body ages, more of your cells become senescent. Senescent cells do not divide or support the tissues of which they...
Heart attack
A new study has found that partial reprogramming mitigates the damage of myocardial infarction in mice by helping heart muscle cells to complete division [1]. When heart cells get stuck When a heart attack (myocardial infarction, MI) kills a patch of heart muscle, the adult mammalian heart cannot replace it, since the lost contractile muscle...
Springtime
For those of us in the Northern Hemisphere, spring is here. This is a time of renewal and hope for better times ahead, echoing what our field is trying to achieve: the rejuvenation of aging cells and tissues to keep older people free from age-related diseases. On that note, let’s take a look at what...
Non-Fungible Conference
