Cytokine & Growth Factor Reviews
|January 26, 1999
Summary
Cytokines and chemokines are key in immune responses and neurological diseases. Glial cells and neurons synthesize and respond to these molecules, influencing conditions like Alzheimer's.
Area of Science:
- Neuroimmunology
- Cellular and Molecular Neuroscience
Background:
- Cytokines and chemokines mediate immune and inflammatory responses.
- These mediators play critical roles in neurological diseases, including Alzheimer's disease, multiple sclerosis, and stroke.
- Within the central nervous system, glial cells and neurons synthesize and respond to cytokines via specific receptors.
Purpose of the Study:
- To discuss the synthesis and response of glial cells and neurons to various cytokines.
- To focus on three key cytokines: interferon-gamma (IFN-gamma), interleukin-6 (IL-6), and transforming growth factor-beta (TGF-beta).
- To explore the significance of these cytokines in neurological diseases with immunological components.
Main Methods:
- Review of literature on cytokine and chemokine roles in the central nervous system.
- Focus on the functions of IFN-gamma, IL-6, and TGF-beta in neurological contexts.
- Analysis of glial cell and neuron interactions with cytokines.
Main Results:
- Glial cells and neurons are capable of both synthesizing and responding to a range of cytokines.
- IFN-gamma exhibits primarily pro-inflammatory effects.
- IL-6 displays both pro- and anti-inflammatory properties, while TGF-beta is predominantly immunosuppressive.
Conclusions:
- Cytokines and chemokines are integral to the neuroimmune landscape.
- The interplay between glial cells, neurons, and cytokines is crucial for understanding and potentially treating neurological disorders.
- Targeting specific cytokines like IFN-gamma, IL-6, and TGF-beta may offer therapeutic strategies for immune-related neurological diseases.

01:29Excitatory and Inhibitory Effects of Neurotransmitters
When an action potential reaches the presynaptic axon terminal, it releases neurotransmitters from the neuron into the synaptic cleft at a chemical synapse. The released neurotransmitter can be excitatory or inhibitory. The critical criteria commonly used to determine whether a molecule is a neurotransmitter at a chemical synapse are the molecule's presence in the presynaptic neuron. Second, its release is in response to strong presynaptic depolarization. And lastly, the presence of specific...
01:20The JAK-STAT Signaling Pathway
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
01:28Cholinergic Antagonists: Pharmacological Actions
Antimuscarinic drugs block muscarinic receptors in multiple systems, including the gut, eye, smooth muscles, respiratory tract, cardiovascular, and central nervous systems. They produce similar effects with varying selectivity depending on the specific agent and tissue. Here are the key pharmacological actions of antimuscarinics:
Gastrointestinal Effects: Antimuscarinics reduce gut contractions, increase gastric emptying, and slow intestinal transit. They partly inhibit gastric acid secretion...

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.

01:27Cytotoxic 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...
