CD79A and colorectal carcinoma: A recent study identified an active tannase enzyme from the oral pathogen Fusobacterium nucleatum48 – only lately described to promote CRC similar to Sgg. Of note, serum anti-Fn antibody IgA combined with carbohydrate antigen 19-9 and carcinoembryonic antigen are reliable screening tools and just as for F. nucleatum49, efforts to use Sgg antibodies as serum biomarkers are on the way for CRC risk stratification50.
