Insights

Carbohydrate-based therapeutics show promise for overcoming immune barriers in organ transplantation, potentially increasing the use of ABO-incompatible donors and enabling future xenotransplantation. These therapies target critical carbohydrate antigens and antibodies involved in transplant rejection.

Area of Science:

  • Immunology
  • Transplantation Medicine
  • Carbohydrate Chemistry

Background:

  • The critical shortage of human organs for transplantation limits treatment options for end-stage organ failure.
  • Blood group ABO-incompatible live donors and xenotransplantation are potential solutions but face significant immunological barriers.
  • Carbohydrate antigens and anti-carbohydrate antibodies represent primary obstacles in both ABO-incompatible transplantation and xenotransplantation.

Purpose of the Study:

  • To explore the role of carbohydrate antigens and antibodies in transplantation immunology.
  • To discuss the chemical characteristics of protein-carbohydrate interactions relevant to transplantation.
  • To review current and experimental carbohydrate-based antirejection therapies and novel antibody adsorber technologies.

Main Methods:

  • Discussion of chemical properties of protein-carbohydrate interactions.
  • Review of experimental and clinical data on carbohydrate-based antirejection therapies.
  • Description of novel mucin-based adsorbers for natural anti-carbohydrate antibodies.

Main Results:

  • Carbohydrate-based therapeutics offer a strategy to mitigate immune responses against transplanted organs.
  • Refined carbohydrate therapeutics may facilitate more ABO-incompatible transplantations.
  • These approaches may address initial immunological hurdles for clinical xenotransplantation.

Conclusions:

  • Carbohydrate-based strategies are crucial for advancing transplantation medicine by overcoming immune incompatibilities.
  • Further development of carbohydrate therapeutics and antibody adsorbers is essential for broader clinical application.
  • These innovations hold the potential to significantly alleviate the organ shortage crisis.

Protein-protein Interfaces02:04

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a polypeptide...
Protein Networks02:26

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...
Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.
Membrane Carbohydrates01:30

Membrane Carbohydrates

The plasma membrane is a dynamic barrier composed of lipids, proteins, and carbohydrates. It is the epicenter of many cellular processes required for cell growth and survival. Carbohydrates have unique structural and chemical properties that help the plasma membrane to carry out its functions effectively.
Membrane carbohydrates do not have any hydrophobic region and are exclusively located on the cell's outer surface. The addition of sugar molecules or glycosylation of proteins happens in...
Tumor Immunotherapy01:27

Tumor Immunotherapy

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.
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...
