The olfactory pathway, where neurons transmit sensory information to the brain, is another potential route for MPs to reach brain tissue. Further research is essential to understand how MPs reach ...

Olfactory ensheathing cells (OECs ... become re-aligned to form a bridging pathway that allows the severed nerve fibres to cross the lesion (Fig. 5). Figure 5: Closure of pathway by astrocytic ...

The new findings raise concerns among researchers that the olfactory pathway might allow microplastics to access the brain and potentially reach brain areas beyond the olfactory bulb.

The findings suggest the olfactory pathway is a potential entry route for microplastics into the brain, Amato-Lourenco noted. "This is the first study to detect and characterize microplastics in ...

A new study published in Nature reveals how olfactory sensory neurons (OSNs) achieve extraordinary precision in selecting ...

Some researchers worry the olfactory pathway may also be an entry point for microplastics getting into the brain, beyond the olfactory bulb. “Previous studies in humans and animals have shown ...

The new study revealed that there was “a potential pathway for the translocation of microplastic to the brain” via the olfactory bulb, raising concerns about their potential role in ...

By having patients sniff odor labels, identify scents and recall what they’d previously smelled, researchers are “hijacking the olfactory pathway, which has direct access to some of the first ...

Engineered Lactobacillus plantarum remained in the nasal passage, where it released its therapeutic payload, which then diffused along the olfactory pathway into the brain. Current approaches to ...

The olfactory pathway may be a potential entry route for microplastics into the brain. Microplastics were found in the olfactory bulbs of eight of 15 human brains at autopsy, a case series showed.
