May 21, 2021 — A novel defense mechanism for SARS-CoV-2 discovered
Akinori Tanaka, Institute for Genetic Medicine

Scientists from Hokkaido University have discovered a novel defensive response to SARS-CoV-2 that involves the viral pattern recognition receptor RIG-I. Upregulating expression of this protein could strengthen the immune response in COPD patients.

October 12, 2020 — Age does not contribute to COVID-19 susceptibility

Ryosuke Omori, Research Center for Zoonosis Control

Scientists have estimated that the age of an individual does not indicate how likely they are to be infected by SARS-CoV-2. However, development of symptoms, progression of the disease, and mortality are age-dependent.

September 8, 2020 – Cellular-level interactions that lead to the cytokine storm in COVID-19

Ryo Otsuka and Ken-ichiro Seino, Institute for Genetic Medicine

Scientists review macrophage activation syndrome — a feature of the cytokine storm that kills patients with severe cases of COVID-19, as well as possible treatments.

August 28, 2020 – Growth rate of the COVID-19 pandemic may be obscured due to changes in testing rates

Ryosuke Omori, Research Center for Zoonosis Control

Scientists have reviewed reported cases and testing data of COVID-19 and have determined that changes in the testing rate may be masking the true growth rate and extent of the pandemic.

August 12, 2020 – A quick, cost-effective method to track the spread of COVID-19 through untreated wastewater

Masaaki Kitajima, Faculty of Engineering

A group of researchers have demonstrated that, from seven methods commonly used to test for viruses in untreated wastewater, an adsorption-extraction technique can most efficiently detect SARS-CoV-2. This gives us another tool to detect the presence and spread of the COVID-19 pandemic.

May 22, 2020 – New technology can detect anti-virus antibody in 20 minutes

Manabu Tokeshi, Faculty of Engineering

Researchers have succeeded in detecting anti-avian influenza virus antibody in blood serum within 20 minutes, using a portable analyzer they have developed to conduct rapid on-site bio tests. If a suitable reagent is developed, this technology could be used to detect antibodies against SARS-CoV-2, the causative virus of COVID-19.
