    Insights

    Cycloferon selectively boosts interferon (IF) gene activity, while amixin inhibits highly active genes. Both drugs influence cell apoptosis (CA) pathways, impacting antiviral responses and IF production.

    Area of Science:

    • Immunology
    • Molecular Biology
    • Pharmacology

    Background:

    • Interferons (IF) and cell apoptosis (CA) are critical for immune response and cellular regulation.
    • Understanding the molecular mechanisms of antiviral drugs like amixin and cycloferon is essential for their therapeutic application.

    Purpose of the Study:

    • To investigate the effects of amixin and cycloferon on gene expression related to interferon (IF) and cell apoptosis (CA).
    • To compare drug-induced gene expression changes with biological interferon activity.
    • To elucidate the molecular basis of the antiviral and IF-inducing properties of these drugs.

    Main Methods:

    • Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) was used to analyze gene expression in human blood microsamples.
    • Dynamic monitoring of gene transcription activity at 24 and 48 hours post-administration.
    • Comparison of gene activity parameters with in vivo and in vitro biological titration of IF activity.

    Main Results:

    • Cycloferon demonstrated a significant, selective stimulation of type I interferon (IF) genes (beta-IF by 100-fold, alpha-IF by 10-fold).
    • Amixin inhibited the expression of highly active genes, including alpha-IF, beta-IF, RNAase L, bcl-2, and gamma-actin.
    • A positive correlation was observed between IF gene transcription activation and total circulating IF production.
    • Antagonistic interactions between type I and type II IFs in human blood cells were identified.

    Conclusions:

    • Cycloferon exhibits potent selective induction of type I interferons.
    • Amixin's mechanism involves the inhibition of specific gene pathways, potentially linked to its antiviral effects via apoptosis.
    • The study highlights the complex interplay between interferon and apoptosis pathways modulated by these drugs.
    • Findings provide insights into the differential molecular actions of amixin and cycloferon on the human immune system.

    Exon Recombination

    The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes. 
    Exon shuffling follows “splice frame rules.” Each exon has three reading...
    Antimicrobial Proteins01:23

    Antimicrobial Proteins

    Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.
    Interferons
    Interferons (IFNs) are proteins produced by lymphocytes, macrophages, and fibroblasts infected with viruses. While IFNs cannot prevent viruses from entering and...
    Inhibitors of Viral Protein Synthesis01:30

    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...
