Toxic Enzymes and Immunotargeting

The research group has many years of experience in the study of plant toxins with rRNA N-glycosylase activity, xanthine oxidoreductase, and pathogenic mechanisms of cellular intoxication, as well as in the implementation and analysis of immunoconjugates for specific drug targeting.

Research projects

  1. The study of plant toxins with rRNA N-glycosylase activity, known for their cytotoxic and antiviral activity.
  2. The study of the pathogenic mechanisms of cellular damage caused by plant toxins.
  3. Experimental immunotherapy for tumors using immunoconjugates.
  4. The study of plant lectins’ cytotoxic and mitogenic properties.
  5. The study of the qualitative and quantitative variations in the enzyme xanthine oxidoreductase in humans with different pathological conditions.

Ongoing research objectives

  1. Purification and characterization of new plant toxins which inactivate ribosomes (rRNA glycosylase).
  2. For ricin and chemical weapons belonging to Schedule 1, according to the Organization for the Prohibition of Chemical Weapons (OPCW): isolation of complex matrices, chemical-physical and quantitative analyses, and immunological and cytotoxic analyses.
  3. Evaluation of the cytotoxic effects and mechandsms of cell deat caused by rRNA N-glycosylase.
  4. Evaluation of the cell signaling pathway created by various serotypes of Chlamydia trachomatis.
  5. Immunoconjugates containing plant rRNA N-glycosylase and an evaluation of their therapeutic effectiveness as an anti-cancer drug in sarcomas and hematological cancers.
  6. Chemosurgery through bicatenary toxins in oculomotor pathologies and for other loco-regional treatments.
