Three hundred and fifty-six bone marrow tissues obtained from patients of a general hospital were tested for spontaneous production after cultivation in vitro of interferon-like substances (ILS). Seventeen percent of the tissues produced ILS that protected human, but not chick, embryo cell cultures against the cytopathic effects of challenge virus infection. The incidence of ILS did not correlate with leukemia or other neoplastic diseases, or with any non-neoplastic disease.

Inhibitors of Viral Protein Synthesis

Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
