A team including HSE researchers has developed a way to use microfluidic chips to assess the toxic effects of drugs on humans. This device will help identify and minimise the side effects of drugs during the preclinical trial stage and reduce the need for animal experiments. The study is published in Bulletin of Experimental Biology and Medicine.

An international team of researchers including biologists from HSE University has developed a method that helps obtain information on changes in protein expression and properties during cells’ transition from one state to another. One of the most interesting transitions is the transformation of cells from undifferentiated stem cells to differentiated cells of various organs and tissues. The paper was published in Nature Communications.

An international team of researchers including Alexander Tonevitsky, Professor at HSE’s Faculty of Biology and Biotechnology, found that pituitary hormones may produce different effects on the left and right sides of the body following a traumatic brain injury. These differences can accelerate the development of motor disorders. Researchers are trying to determine whether treatment that blocks the corresponding hormones can counteract these effects. The results of the study were published in the journal eLife.

Researchers from HSE University have developed new approaches for regulating the expression of ACE2 and TMPRSS2 enzymes, which play a crucial role in cell infection with SARS-CoV-2. The scholars discovered that small non-coding microRNA (miRNA) molecules are capable of performing a targeted decrease in ACE2 and TMPRSS2. The results of the study have been published in PLOS ONE journal.

First-year undergraduate students of the HSE Faculty of Biology and Biotechnology took part in an online seminar at George Mason University (USA). The seminar was part of the Coronavirus Research Update summer course, taught by Professor Ancha Baranova.

The Shemyakin and Ovchinnikov Institute of Bioorganic Chemistry  (IBCH RAS) is one of the institutes of the Russian Academy of Science involved in the development of new faculties at the HSE University. It is also where first-year biology students come for hands-on training in research laboratories, and, in some cases, internships. HSE News Service visited the Institute to speak with first-year students at a zoology workshop.
