Research Overview
IFN-alpha-2b
Extensively studied recombinant type I interferon with direct antiviral and immunoregulatory effects. Clinical literature spans hepatitis treatment, antiviral research, and immune-oncology contexts.
Thymopentin
Thymopentin has a long history of preclinical and clinical investigation as a thymic peptide immunomodulator. Published studies report effects on T-cell subsets, cytokine responses, and immune recovery in recurrent infection settings.
