Two distinct circuits drive inhibition in the sensory thalamus of the brain

The thalamus is a 'Grand Central Station' for sensory information coming to our brains. Almost every sight, sound, taste and touch travels to our brain's cortex via the thalamus. Researchers now report that the somatosensory part of the thalamic reticular nucleus is divided into two functionally distinct sub-circuits that have their own types of genetically defined neurons that are topographically segregated, physiologically distinct and connect reciprocally with independent thalamocortical nuclei via dynamically divergent synapses.

Cells react differently to genomic imprinting

We inherit half of our genes from each parent. For their function of most genes, it doesn't matter which parent a gene comes from. But this is not true for all genes: about 150 genes are subject to ''genomic imprinting''. They are active either only if inherited from the mother, or only father. Most ''imprinted'' genes are important for our development. New research shows that brain cells react differently to genomic imprinting.

Researchers have created a virus in the lab that infects cells and interacts with antibodies just like the COVID-19 virus, but lacks the ability to cause severe disease. This safer virus makes it possible for scientists who do not have access to high-level biosafety facilities to join the effort to find drugs or vaccines for COVID-19.

Chinese phase 2 trial finds COVID-19 vaccine is safe and induces an immune response

A phase 2 randomized controlled trial of a recombinant adenovirus type-5-vectored COVID-19 vaccine (Ad5-vectored COVID-19 vaccine) was conducted in China in April 2020 and involved more than 500 people. The primary objective of the study was to evaluate the immune response and safety of the vaccine, and to determine the most suitable dose for a phase 3 trial. Phase 3 trials are needed to confirm whether the vaccine candidate effectively protects against SARS-CoV-2 infection.

UK's vaccine against SARS-CoV-2 is safe and induces an immune reaction, according to preliminary results

A phase 1/2 trial involving 1,077 healthy adults found that the vaccine induced strong antibody and T cell immune responses up to day 56 of the ongoing trial. These responses may be even greater after a second dose, according to a sub-group study of 10 participants. Compared to the control group (given a meningitis vaccine), the SARS-CoV-2 vaccine caused minor side effects more frequently, but some of these could be reduced by taking paracetamol. There were no serious adverse events from the vaccine. Based on their results, the authors say that further clinical studies, including in older adults, should be done with this vaccine. The current results focus on the immune response measured in the laboratory, and further testing is needed to confirm whether the vaccine effectively protects against infection.

The sympathetic nerve reacts to cold by contracting the muscle and causing goosebumps in the short term, and by driving stem cell activation and new hair growth over the long term.

Credit-card sized tool provides new insights into how cancer cells invade host tissues

Researchers have developed a credit-card sized tool for growing cancer cells outside the human body, which they believe will enhance their understanding of breast cancer metastasis. The device reproduces various environments within the human body where breast cancer cells live. Studying the cells as they go through the process of invasion and metastasis could point the way toward new biomarkers and drugs to diagnose and treat cancer.
