Using the glycan toolbox for pathogenic interventions and glycan immunotherapy.

Area of Science:

• Immunology
• Glycobiology
• Biotechnology

Background:

• Glycans act as critical recognition elements for immune cell receptors, including C-type lectin receptors (CLRs) and Siglec receptors.
• These interactions are vital for distinguishing self from foreign entities, influencing innate immunity, adaptive immunity, and immune signaling pathways.

Purpose of the Study:

• To explore the immunomodulatory roles of glycan recognition by CLRs and Siglecs.
• To investigate the potential of exploiting these glycan-receptor interactions for developing novel therapeutics in cancer and infectious diseases.

Main Methods:

• Analysis of glycan recognition mechanisms by CLRs and Siglecs on immune cells.
• Review of the impact of glycan binding on immune responses, including pathogen recognition, T-helper differentiation, cytokine production, and antigen presentation.

Main Results:

• Glycan recognition by CLRs significantly modulates immune responses, affecting pathogen binding, immune signaling, T-helper cell differentiation, cytokine release, and antigen presentation.
• These glycan-mediated immune modulations are implicated in the pathogenesis of infectious diseases and cancer.

Conclusions:

• Glycan interactions with CLRs and Siglecs are crucial for immune surveillance and have significant implications in disease pathogenesis.
• Targeting these glycan-receptor interactions presents a promising avenue for developing glycan-based immunotherapies and therapeutics for cancer and infectious diseases.
• The multivalent nature of these interactions necessitates advanced biotechnological approaches for effective therapeutic intervention.
