Research Overview

IFN-beta-1a

Widely studied recombinant interferon beta preparation with a strong evidence base in immune modulation and antiviral biology. Its clinical use demonstrates predictable pharmacology and class-typical interferon effects.

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.
