Anticancer and Immunomodulatory Effects of Polysaccharides

Area of Science:

• Biochemistry
• Immunology
• Oncology

Background:

• Cancer represents a major global health challenge, necessitating novel therapeutic strategies.
• Biologically active polysaccharides and polysaccharide-protein complexes from various natural sources exhibit promising antitumor and immunomodulatory properties.
• The immune system's role in cancer surveillance is critical, making immune enhancement a potential therapeutic avenue.

Purpose of the Study:

• To explore the anticancer and immunomodulatory potential of natural polysaccharides.
• To investigate the mechanisms by which polysaccharides affect tumor cells and the host immune system.
• To evaluate polysaccharides as a less toxic alternative to conventional chemotherapy.

Main Methods:

• Isolation and characterization of polysaccharides from diverse natural sources (plants, fungi, algae, etc.).
• In vitro and in vivo studies to assess direct cytotoxic effects on cancer cells (growth inhibition, apoptosis induction).
• Evaluation of immunomodulatory activities, including enhancement of host immune responses against tumors.

Main Results:

• Polysaccharides demonstrate dual mechanisms of action: direct inhibition of cancer cell proliferation and induction of apoptosis.
• Significant stimulation of the host immune system observed, aiding in cancer cell immune surveillance.
• Polysaccharides exhibit favorable therapeutic profiles with lower toxicity compared to traditional chemotherapy.

Conclusions:

• Natural polysaccharides possess significant anticancer potential through direct and indirect mechanisms.
• Their immunomodulatory properties offer a promising strategy for cancer therapy by bolstering host immunity.
• Polysaccharides represent a valuable class of compounds for developing effective and less toxic cancer treatments.
