Tumor Immunotherapy01:27

Tumor Immunotherapy

2.0K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Proteoglycans

4.9K
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...

Protein Glycosylation01:25

Protein Glycosylation

9.9K
Glycosylation, the most common post-translational modification for proteins, serves diverse functions. Adding sugars to proteins makes the proteins more resistant to proteolytic digestion. Glycosylated proteins can act as markers and receptors to promote cell-cell adhesion. Additionally, they have many essential quality control functions in the cell, such as correct protein folding and facilitating transport of misfolded proteins to the cytosol, which can be degraded.

Summary

Glycans are key for immune cells to distinguish self from foreign invaders. Harnessing glycan interactions with C-type lectin receptors (CLRs) and Siglecs offers new therapeutic strategies for cancer and infectious diseases.

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.
