7.5 Immune receptor blocking may reverse aging in mice¶

Stanford Medicine researchers found that blocking a single immune receptor on tissue-resident macrophages restored their ability to clear senescent neutrophils, reducing inflammation and maintaining youthful function across multiple organs in aged mice. The intervention protected mice from frailty, excess fat accumulation, heart trouble, and substantially reduced cognitive decline. The findings suggest aging may be partly driven by immune cells losing their ability to dispose of damaged, inflammation-promoting cells.

7.5 Vesper bats possess unique dual antibody gene system enabling virus tolerance¶

Scientists at Tulane University discovered that over 500 species of vesper bats possess two separate sets of antibody genes, an arrangement never before found in any mammal. The dual heavy-chain gene system may enable bats to create a wider variety of antibodies and help explain how they tolerate viruses that cause severe disease in other animals. The finding was published in Science Advances on September 3, 2026.

7.5 Ionis wins FDA approval for Zanvastro, first disease-modifying treatment for Alexander disease¶

The FDA approved Zanvastro, the first disease-modifying therapy for Alexander disease, a rare and fatal neurological disorder. In the pivotal trial, walking speed remained stable in treated patients while the control group declined 33%, with hints that early treatment in young children could improve motor function.
