Summary
Nuclear factor-kappa B (NF-κB) signaling regulates immune responses and T-cell differentiation. This review explores NF-κB
Area of Science:
- Immunology and Molecular Biology
- Focuses on cellular signaling pathways in adaptive immunity.
Background:
- Nuclear factor-kappa B (NF-κB) is crucial for immune responses, apoptosis, and inflammation.
- NF-κB signaling impacts immune cell development and function, regulating cytokine and chemokine expression.
- Naive CD4(+) T cells differentiate into specialized subsets (Th1, Th2, Th17, Th9, Tfh, Th22, Treg) based on environmental cues.
Purpose of the Study:
- To review the critical role of the NF-κB pathway.
- To elucidate NF-κB's involvement in the development and functional divergence of T-helper cell subsets.
- To examine NF-κB's function in regulatory T cells (Treg).
Main Methods:
- Literature review of existing research on NF-κB signaling.
- Analysis of studies investigating T-cell differentiation pathways.
- Synthesis of findings on NF-κB's impact on various T-cell subsets.
Main Results:
- NF-κB signaling is integral to the differentiation and function of diverse T-helper cell subsets.
- The pathway influences the balance between effector and regulatory T-cell populations.
- Specific roles of NF-κB in Th1, Th2, Th17, Th9, Tfh, Th22, and Treg cell development are highlighted.
Conclusions:
- NF-κB is a key regulator in adaptive immunity, directing T-cell subset development.
- Understanding NF-κB's role is vital for modulating immune responses and treating immune-related diseases.
- Further research into NF-κB signaling can unlock new therapeutic strategies for immune disorders.

02:26NF-κB-dependent Signaling Pathway
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

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.

01:22T Cell Activation and Clonal Selection
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

02:04Co-activators and Co-repressors
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...
01:27Cytotoxic T Cells-mediated Immune Response
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
