The SARS-CoV spike protein and its receptor

The SARS-CoV-2 coronavirus uses a spike protein to bind to the ACE2 receptor on the cell surfaces of lung tissue. Additional cofactors are needed to allow the virus genome to penetrate human cells and multiply. Knowing these relationships can help understand the course of the infection and develop counterstrategies. To this end, the Constance-based company Trenzyme has produced a recombinant spike protein to support coronavirus research.

Diagnostics with molecular scissors – is this also possible for on-site COVID-19 tests?

The CRISPR-Cas gene-editing technology is one of the most important developments in molecular biology in recent years. It utilises molecular scissors with which nucleic acids can be cut and edited almost arbitrarily. Researchers in Freiburg, Germany have now successfully used the technology for diagnostic purposes. They are currently working intensively on expanding the system to enable it to detect genome sequences of the novel SARS-CoV-2 virus.

The start-up 3a-diagnostics GmbH from Frickenhausen is developing a gum that can be used both in doctors’ surgeries and at home as a quick and easy diagnostic aid. The sensor in this case is the human tongue. If bacteria are present – due to an inflammation of the teeth or tonsils, for instance – chewing produces a bitter taste and the doctor can quickly initiate the appropriate treatment.

Medications that target metastasing tumours

Tumour metastases are often resistant to the drug that is used to eliminate the primary tumour. Genome-wide analyses of mutation patterns in the primary tumour and its metastases provide information on the aggressiveness of cancer and may help to find the best available means of further treatment. This has been demonstrated by scientists from Heidelberg in a clinical trial on the molecular evolution of renal cancer.

CureVac AG, a leading clinical-stage biopharmaceutical company focused on the development of pioneering mRNA therapeutics, and Arcturus Therapeutics Ltd. (NASDAQ:ARCT), an RNA medicines company, today announced they have entered into a broad strategic collaboration to jointly discover, develop and commercialize novel messenger RNA (mRNA) therapeutics.

Personalised antibiotics therapy: fewer antibiotic-resistant bacteria

Antibiotics have long been used as all-purpose weapons against infectious diseases – too often and too early, as we now know. This tendency has caused many bacteria to become resistant to standard antibiotics. The search for new substance classes has proved quite difficult. Care must therefore be taken to use existing antibiotics prudently in order to reduce the number of bacteria becoming resistant to them in the long term. Researchers from…
