Summary
Glucocorticoid resistance and T-helper 17 (Th17) cells play a key role in depression pathogenesis. Increased Th17 activity correlates with depression severity, highlighting their impact on neuroinflammation.
Area of Science:
- Neuroscience
- Immunology
- Psychiatry
Background:
- Depression is a complex mental disorder with unclear pathogenesis, despite various theories.
- Steroid resistance, affecting brain and immune cells, is a key feature of depression.
- T-helper 17 (Th17) cells exhibit glucocorticoid resistance, unlike other T-helper cells.
Purpose of the Study:
- To review the interplay between glucocorticoid resistance and Th17 lymphocytes in depression.
- To explore the mechanisms linking Th17 cells to neuroinflammation in depression.
Main Methods:
- Literature review focusing on recent findings.
- Analysis of the role of glucocorticoids and Th17 cells in depression.
- Discussion of immune cell involvement in neuropsychiatric disorders.
Main Results:
- Glucocorticoids enhance Th17 differentiation and IL-17A production in resistant conditions.
- Elevated Th17 cell counts and IL-17A levels are observed in depression, particularly treatment-resistant cases.
- Increased Th17 activity correlates with depression severity.
Conclusions:
- Th17 cells and glucocorticoid resistance are significantly implicated in depression pathogenesis.
- Further research is needed to elucidate the precise mechanisms of Th17-mediated neuroinflammation in depression.

01:24T Cell Types and Functions
1.0K
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.

01:29Pulmonary Tuberculosis I
244
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

01:21Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
121
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

01:37Hypothalamic-Pituitary Axis
60.2K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

01:29Autoimmune Disorders
447
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.
