What we say:
Dr L Boominathan PhD, Director-cum-chief Scientist of GBMD, reports that: Probiotics function as anti-HIV agents: Probiotic Streptococcus thermophilus increases Heme oxygenase 2 (HO-2) expression, blocks N-myristoylation of HIV-1 Gag protein, disrupts HIV-1 budding, and restricts HIV-1 production, via upregulation of its target gene
From Significance of the study to Public health relevance:
Given that: (1) more than 37 million people worldwide are living with HIV/AIDS; (2) there is no effective vaccine available for HIV/AIDS; (3) HIV/AIDS tops the list of incurable diseases in humans; (4) the life-long painful drug treatment is required to treat HIV/AIDS and its associated opportunistic infections; (5) the global economic cost spent for HIV treatment is enormous, there is an urgent need to find: (i) a way to restore CD4 T-cells that were lost in HIV/AIDS; (ii) a cheaper alternative to the existing expensive antiviral drugs; (iii) a side-effect-free natural product-based drug; and (iv) a way to cure, not just treat, HIV-1/AIDS.
Research findings to Therapeutic opportunity:
A number of studies suggest that probiotics may protect against a number of bacterial infections. However, the mechanism of action remains unclear. I had published earlier that probiotics may function as anti-infective agents–presented with detailed mechanistic insights– against a number of bacterial and viral infections.
This study suggests a probiotic-based antiviral therapy against RNA viruses such as HIV-1. Probiotic Streptococcus thermophilus, by increasing the expression of its target gene, it may increase the expression of Heme oxygenase-2 (HO-2) (Figure 1). Thereby, it may: (1) bind and block the myristate moiety of HIV-1 Gag protein; (2) disrupt HIV-1 budding; (3) restrict HIV-1 infectivity, replication, and production; (4) promote clearance of HIV-1 and MLV virions; and (5) strengthen antiviral immunity against RNA viruses (fig.2). Thus, Probiotic Streptococcus thermophilus, either alone or in combination with other drugs,” may be used to inhibit HIV-1 production. Together, this study suggests that: (1) Probiotic Streptococcus thermophilus may function as an anti-retroviral agent against HIV infections, and (2) daily intake of Probiotic Streptococcus thermophilus may protect against HIV1 infections.
