Researchers at the Walter and Eliza Hall Institute of Medical Research (WEHI) in Melbourne have discovered new cells that drive the aging process in the thymus that could unlock a way to restore function and prevent immunity from waning as we age. The thymus is the first organ in the body to shrink as people age. As this happens, the T-cell growth areas in the thymus are replaced with fatty tissue, diminishing T-cell production and contributing to a weakened immune system.
Scientists at Harvard Medical School have shown that in mice lacking amyloid beta (Aβ), the fundamental hallmark of Alzheimer's disease (AD), neurons died from the effect of the most harmful mutation of this neurodegenerative disease. They showed that presenilin (PS) could be behind the origin of the disease without the need for Aβ. They maintain that it is time to update theories and redirect efforts.
Researchers in Japan were able to transfer genes from jellyfish into common fruit flies and discovered that the transferred gene suppressed an age-related intestinal issue in the flies. The findings suggest that studying genes specific to animals with high regenerative capability like jellyfish may uncover new mechanisms for rejuvenating stem cell function and extending the healthy lifespan of unrelated organisms.

An abnormal epigenetic modification of RNA could be related to senescence and aging disorders, pointing towards the enzyme methyltransferase-like 1 (METTL1) as a potential therapeutic target.
Increased life expectancy also comes with age-related diseases. But what causes one to age? Although there is no single answer, scientists at Duke-National University of Singapore have shown in mice that interleukin-11 (IL-11) promoted aging. Blocking it improved health and lifespan.

Age-related inflammation, also known as inflammaging, refers to low-grade chronic damage caused by increased inflammation linked to immunosenescence with impact at molecular, cellular and tissue levels. Aging amplifies the inflammatory response and increases neutrophil, monocyte and leukocyte trafficking in models of inflammation.
Immuneage Bio has announced its launch, with $2 million in funding and a focus on rejuvenating the immune system by targeting hematopoietic stem cells (HSCs) residing in the bone marrow.
Altos Biologics Inc., founded as an eye disease-focused subsidiary of Alteogen Inc. in 2020, raised ₩24.5 billion (US$17.7 million) in a series B financing round to advance its pipeline of therapeutics for eye-related conditions, including age-related macular degeneration (AMD). Daejeon, South Korea-based Alteogen said July 9 that the funds raised will be funneled to develop OP-01, Altos’ candidate therapy for AMD.
