BAF restricts cGAS to nuclear DNA to prevent innate immune activation

A loose BAF places the foot on the cGAS A signaling pathway in vertebrates called cGAS-STING detects the presence of intercellular DNA as a substitute for both cell damage and viral infection. At the same time, the sense of self-DNA must be suppressed to prevent the development of autoimmune responses. Gueye et al. identify barrier factor against autointegration factor (BAF) …

Bacterial enzymes ‘grab’ to create complex molecules normally made by plants

Credit: CC0 Public Domain Chemists at Scripps Research have efficiently created three families of complex, oxygen-containing molecules that can normally only be obtained from plants. These molecules, called terpenes, are potential starting points for new drugs and other high-value products – marking an important development for many industries. Moreover, the new approach could allow chemists to build many other classes …
