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.
Thymalin
Thymalin appears in Soviet/Russian clinical literature as a thymus peptide complex used to normalize immune parameters after illness, surgery, or radiation exposure. Reports commonly focus on changes in lymphocyte subsets, phagocytic activity, and infection frequency rather than a single isolated peptide mechanism.
