MAF Capsules and M Capsules are dietary supplements produced by Saisei Pharma, Japan. They are designated to modulate the mucosal immunity of the intestine. The main active ingredients of both products are vitamin D binding protein (VDBP) and other glycoproteins which undergo degalactosylation during the process of β-Galactosidase treatment applied to the whole heat-inactivated bovine colostrum in the case of MAF Capsules and to bovine whey in the case of M Capsules. This treatment converts VitD ~ VDBP into VitD-degalactosylated VDBP. The functional activity of degalactosylated VDBP is similar to that seen in the group-specific component macrophage activating factor (GcMAF). GcMAF is a protein that results from the sequential deglycosylation of its precursor – VDBP.
The hypothesis: Based on the aforementioned findings and on documented analogies between SARS-CoV-2 and HIV, we hypothesized that the reduced conversion activity of the Gc protein (human group-specific component (Gc)) into the macrophage activating factor (MAF) could have a key role in the dysregulate immune response induced by SARS-CoV-2, just like for HIV infected patients. If this hypothesis is correct, it might help to set a valid strategy of immunotherapy also based on an off-label use of GcMAF in critically ill COVID-19 patients.
