Nogo-A targeted therapy promotes vascular repair and functional recovery following stroke.

Stroke is a major cause of serious disability due to the brain's limited capacity to regenerate damaged tissue and neuronal circuits. After ischemic injury, a multiphasic degenerative and inflammatory response is coupled with severely restricted vascular and neuronal repair, resulting in permanent functional deficits. Although clinical evidence indicates that revascularization of the ischemic brain regions is crucial for functional recovery, no therapeutics that promote angiogenesis after cerebral stroke are currently available.

Providing reducing power by microalgal photosynthesis: a novel perspective towards sustainable biocatalytic production of bulk chemicals exemplified for aliphatic amines.

A biotechnological process is reported, which enables an enzymatic reduction without the need for addition of an organic co-substrate for in situ-cofactor recycling. The process is based on merging the fields of enzymatic reductive amination with formate dehydrogenase-based in situ-cofactor recycling and algae biotechnology by means of the photoautotrophic microorganism Chlamydomonas reinhardtii, providing the needed formate in situ by formation from carbon dioxide, water and light. This biotransformation has been exemplified for the synthesis of various aliphatic amines known as bulk chemicals.
