Summary
Regulatory T cells (T(reg)) control the immune system. Retinoic acid (RA) influences T(reg) cell function, homing, and differentiation, offering new insights into immune regulation and vitamin A
Area of Science:
- Immunology
- Molecular Biology
- Cell Biology
Background:
- The discovery of regulatory T cells (T(reg)) has significantly advanced understanding of immune system control.
- Emerging research highlights the role of retinoic acid (RA) in T(reg) cell biology.
Purpose of the Study:
- To explore the intersection of retinoic acid (RA) signaling pathways and regulatory T cell (T(reg)) function.
- To leverage existing knowledge of RA's molecular actions to elucidate its effects on T(reg) cells.
Main Methods:
- Review and integration of existing research on RA molecular mechanisms, receptors, and cellular differentiation.
- Reinterpretation of historical findings on vitamin A and immunity in the context of T(reg) cell control.
Main Results:
- Retinoic acid (RA) has been identified as a key regulator of both T(reg) cell homing and differentiation.
- Established knowledge of RA's molecular basis provides a framework for understanding its impact on T(reg) cells.
Conclusions:
- Retinoic acid (RA) plays a critical role in modulating leukocyte homing and regulatory T cell (T(reg)) function.
- This understanding opens new avenues for investigating immune responses and potential therapeutic interventions.

01:24T Cell Types and Functions
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

01:23Cells of the Adaptive Immune Response
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
01:27Tumor 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.
01:29Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...
01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
