Cover Story: This figure represents three consecutive steps of viral infection and their pathways of inhibition by microalgal antioxidants, including sulfated polysaccharides, tannins, or phycobiliproteins. Viral infections are often favored by oxidative processes, promoting the development of infection from stage I (adhesion, adsorption) to stage III (release of virus particles), through stage II (replication). Antioxidants can contribute to limit viral diseases, while the diversity, richness, and peculiarity of bioactive compounds confers to microalgal derivatives a pole position in these functions. Activities of microalgal antioxidants against viruses need to be further explored, from the biodiversity of organisms and moieties to mechanisms of action, and deserve to be exploited in the fight against human viral infection.
