Why Older Fathers Pass On More Genetic Mutations to Their Offspring

Study of fruit flies reveals genetic mutations are common in the testes of both young and old males, but the mutations are more abundant in older insects. Many of the mutations are removed in the younger flies during spermatogenesis by the body's genetic repair mechanism, but spermatogenesis fails to repair the mutations in older flies.

Common Alzheimer’s Gene Variant Linked to COVID Mortality

Mice with the Alzheimer's disease-associated APOE4 and the APOE2 genes were more likely to die from COVID-19 than those with the APOE3 gene. Those with APOE4 and APOE2 genes had more virus replication in the lungs, higher inflammation, and increased tissue damage following coronavirus infection.

Study Detects Origins of Huntington’s Disease in Two-Week-Old Human Embryos

Synthesizing a human embryo from stem cells and using gene editing to insert the Huntingtin gene, researchers found the mutation affected the size of germ layers compared to the control embryos. Findings suggest Huntington's disease may be a neurodevelopmental disorder that presents as a neurodegenerative disease later

Brain Disease Transmitted By Tick Bites May Be Treatable

Researchers have identified specific anti-bodies that can have a neutralizing effect on the virus responsible for tick-borne encephalitis. Preliminary response in using the anti-bodies in mice has proven affected in preventing TBE. It is hoped a vaccine candidate for TBE can be developed for humans.
