Scientists at Lund University, Sweden showed that it is possible to prevent type 2 diabetes in mice by inhibiting a protein known as VDAC1. This inhibitor might be employed in treating this disease in humans [1]. Abstract Type 2 diabetes (T2D) develops after years of prediabetes during which high glucose (glucotoxicity) impairs insulin secretion. We…

Senolytics are the first therapies that directly target the aging process to delay or prevent age-related diseases and are now in human trials. Today we thought it was the ideal time to have a look at how they work and the companies involved. Senescent cells and aging As we get older, more and more of…

Researchers at the Imperial College London have discovered that specifically employing invariant natural killer T cells, rather than generic T cells, in cancer immunotherapies based on chimeric antigen receptors might lead to significantly more effective, cheaper, and more easily mass-produced treatments [1]. Abstract Chimeric antigen receptor anti-CD19 (CAR19)-T cell immunotherapy-induced clinical remissions in CD19+ B…

Scientists from the A*STAR Singapore Immunology Network have discovered that immune cells called nonclassical monocytes undergo cellular senescence, contradicting what was previously thought of them [1]. Abstract Human primary monocytes comprise a heterogeneous population that can be classified into three subsets based on CD14 and CD16 expression: classical (CD14high/CD16−), intermediate (CD14high/CD16+), and non-classical (CD14low/CD16+). The…

Today, we are going to be taking a look at GAIM and what it might mean for treating amyloid-based diseases, such as Alzheimer’s, Parkinson’s, and amyloidosis. This approach has the potential to treat multiple age-related diseases at once by targeting a common characteristic that they all share. Misfolded proteins cause multiple age-related diseases Proteins are…

Researchers at the Department of Biological Sciences at Lehigh University in Bethlehem, Pennsylvania, discovered that a protein known as Scarlet has protective effects against the fruit fly version of Parkinson’s disease [1]. Abstract Parkinson’s Disease (PD) is characterized by the loss of dopaminergic neurons, resulting in progressive locomotor dysfunction. Identification of genes required for the…

Today, we want to bring your attention to a recent mouse study on fisetin, a commonly available supplement that has proven effective at destroying senescent cells. What are senescent cells? As we age, increasing amounts of our cells enter into a state known as senescence. Normally, these cells destroy themselves by a self-destruct process known…

Led by Dr. Alicja Copik, scientists at the University of Central Florida College of Medicine have discovered that it might be possible to make cancer immunotherapy work for a larger portion of patients by employing PM21-activated natural killer (PM21-NK) cells [1]. Study abstract Anti-PD-1/anti-PD-L1 therapies have shown success in cancer treatment but responses are limited…

A recent open-access mouse study published by Xi’an Institute of Tissue Engineering and Regenerative Medicine scientists in the journal Bone Research describes how the ALPL gene affects bone aging and suggests that metformin might constitute a viable therapeutic option to prevent it [1]. Study abstract Mutations in the liver/bone/kidney alkaline phosphatase (Alpl) gene cause hypophosphatasia…

A study from the UNC School of Medicine showed that the protein NLRP12, known for its anti-inflammatory effects, also protects mice on a high-fat diet against obesity and insulin resistance; it might have a similar effect in humans [1]. Study abstract In addition to high-fat diet (HFD) and inactivity, inflammation and microbiota composition contribute to…
