Although these researchers speculated that crude saliva [8], MUC5B and MUC7 [2], two of the known mucins in saliva [23] are potentially involved in inhibition through the entrapment of virus particles, a definitive attempt to purify, identify and individually test these purified mucins from saliva, against the AIDS virus, has not been done. The gene discussed is MUC5B; the disease is AIDS.
