Immunohistochemistry News and Research

RSS

Immunohistochemistry (IHC) is an imaging technique to visualize antigens in cells. Labeled antibodies bind to target antigens in the cell to image the distribution and localization of specific proteins of interest

Epigenomic modifications play key role in the development of lung tumors

As cancer cells evolve, many of their genes become overactive while others are turned down. These genetic changes can help tumors grow out of control and become more aggressive, adapt to changing conditions, and eventually lead the tumor to metastasize and spread elsewhere in the body.

SARS-CoV-2 invasion of central nervous system through olfactory tract

As the COVID-19 pandemic continues to claim lives throughout the world, the evidence is mounting that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) affects the respiratory tract as well as the central nervous system. Now, a new study by German researchers published on the preprint server bioRxiv in June 2020 describes various neurological manifestations of COVID-19, as well as the underlying pathophysiology.

No specific COVID-19-linked lesions found despite extensive organ injury

A recent paper published online on the preprint server medRxiv in May 2020 reports autopsy results on COVID-19 patients. The paper concludes that there were no specific hallmark lesions of COVID-19 in any of the many organs found to be injured by the infection in patients who died of the disease.

Study shows children and adults have a comparable expression of SARS-CoV-2 entry-related genes

A recent paper by researchers from China demonstrated comparable expression levels of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cell entry mediators in adults and children, suggesting that previously implied difference in viral-entry associated genes is likely not responsible for milder symptoms in children. The study is currently available on the medRxiv preprint server.
