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.
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.
Researchers suggest that when in a group, ants behave in a similar fashion to networks of neurons in the brain.
While the overall memories of an experience are stored in the hippocampus, individual details are parsed and stored in the prefrontal cortex.
Study reveals dopamine neurons that play a role in learning and memory also drive motivation.
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
A new technique dubbed light beads microscopy allowed researchers to generate a vivid functional movie of the near-simultaneous activity of almost a million neurons in the mouse brain.
A new microscopy technique allows researchers to capture detailed images of the activity of vast amounts of neurons across different depths in the brain at high speed and clarity.
Researchers have identified a novel population of neurons in the temporal pole that links facial perception to long-term memory.
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.
Researchers have identified a pathway involving a protein called Rab35 in glioblastoma brain cancer. The study reports restoring the activity of Rab35 could have therapeutic benefits for those with glioblastoma.
SARS_CoV_2, the virus responsible for COVID-19, can directly enter the nervous system. The virus can infect the brain, causing alterations in blood vessels and directly disrupt oxygen supply to the organ.
