T Cell Types and Functions01:24

T Cell Types and Functions

2.0K
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.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Psychoneuroimmunology: Cardiovascular Disease

352
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

15.2K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

11.7K
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...

Nephrotic Syndrome II : Assessment and Medical Management

169
IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...

Skin Diseases and Disorders

5.1K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Summary
This summary is machine-generated.

Psoriasis can cause a serious eye condition called uveitis, affecting 7-20% of patients, especially those with psoriatic arthritis. Shared inflammatory pathways suggest similar biologic therapies may benefit both conditions.

Area of Science:

  • Ophthalmology
  • Rheumatology
  • Immunology

Background:

  • Uveitis is a serious ocular complication of psoriasis, though data on its characteristics are limited.
  • It affects an estimated 7-20% of psoriasis patients, with higher incidence in those with psoriatic arthritis.
  • Psoriatic uveitis is typically bilateral, chronic, and severe.

Purpose of the Study:

  • To review the characteristics and pathogenesis of uveitis in patients with psoriasis.
  • To highlight the shared inflammatory pathways and potential therapeutic targets.

Main Methods:

  • Literature review focusing on the association between psoriasis and uveitis.
  • Analysis of pathogenetic mechanisms, including key cytokines and T-helper cell involvement.

Main Results:

  • Psoriasis and uveitis share common T-helper 1/T-helper 17 (Th1/Th17) inflammatory pathways.
  • Cytokines like TNF-α, IL-17, IL-23, and IL-6 are implicated in both conditions.
  • Psoriatic uveitis may benefit from targeted biologic therapies used for psoriasis.

Conclusions:

  • Psoriatic uveitis is a significant complication requiring further investigation.
  • Shared pathogenesis suggests potential for unified treatment strategies.
  • Undiagnosed or undertreated cases can lead to vision loss, emphasizing the need for awareness and research.
