Animals depend on their sense of smell to locate food, identify mates and evade danger. In mammals, olfactory perception typically relies on G protein–coupled receptor (GPCR) pathways. Insects, by ...

A new study from Griffith University has found that certain bacteria can travel directly from the nose into the brain, ...

New research reveals that microplastics can penetrate the brain through the nasal passages, prompting urgent questions about their impact on human health and the environment. Study: Microplastics in ...

Adult neural stem cells/progenitor cells residing in the basal layer of the olfactory epithelium are capable of reconstituting the neuroepithelium even after severe damage. The molecular events ...

A new study has presented more evidence backing up a hypothesis suggesting viral infections in the olfactory system can accelerate the progression of Alzheimer's disease (AD). Instead of focusing on ...

Olfactory ensheathing glia (OEG) play an important role in regulating the regeneration of an injured nervous system. However, chronic inflammation damage reduces the viability of OEG via poorly ...

Microplastics were found in the olfactory bulbs of eight of 15 human brains at autopsy, a case series showed. A total of 16 synthetic polymer particles and fibers were identified, reported Luís ...
