Summary
The CD99 antigen, a transmembrane protein, plays dual roles in cancer, acting as both an oncogene and tumor suppressor. Targeting CD99 with antibodies shows promise for cancer immunotherapy, particularly in Ewing sarcoma and T cell acute lymphoblastic leukemia.
Area of Science:
- Immunology
- Oncology
- Cell Biology
Background:
- CD99 antigen is a transmembrane protein found in various tissues, notably hematopoietic cells and endothelial cells.
- It is involved in fundamental biological processes like cell adhesion, migration, differentiation, and inflammation.
- CD99 exhibits context-dependent roles in cancer, functioning as either an oncogene or a tumor suppressor.
Purpose of the Study:
- To review recent advancements in CD99 research concerning cancer development and targeted therapies.
- To explore the potential of CD99 as a biomarker and therapeutic target in oncology.
- To highlight CD99's emerging role in cancer immunotherapy.
Main Methods:
- Literature review of studies on CD99's function in cancer and immunity.
- Analysis of CD99's involvement in key cellular processes relevant to cancer.
- Examination of therapeutic strategies targeting CD99, including antibody-based treatments.
Main Results:
- CD99 influences critical immune processes, including T cell and dendritic cell differentiation.
- Anti-CD99 antibodies have demonstrated therapeutic efficacy in specific cancers like Ewing sarcoma and T cell acute lymphoblastic leukemia (ALL).
- CD99's dual role necessitates careful consideration for therapeutic strategies.
Conclusions:
- CD99 is a significant factor in cancer development and immune responses.
- Targeting CD99 presents a promising avenue for novel cancer immunotherapy strategies.
- Further research into CD99's mechanisms can guide the development of more effective cancer treatments.

01:20Cell Adhesion Molecules - Types and Functions
7.1K
Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).

3.4K
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

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.

3.4K
Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain,...

6.6K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
