Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

14.8K
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...

T Cell Types and Functions01:24

T Cell Types and Functions

1.6K
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...

Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

89
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Structural Joints: Synovial Joints

5.3K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Rheumatic Heart Disease I: Introduction

122
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

9.7K
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...

Area of Science:

  • Rheumatology and Immunology
  • Dermatology

Background:

  • Psoriatic arthritis (PsA) is a heterogeneous inflammatory disease complicating psoriasis in 30% of patients.
  • Current diagnosis relies on identifying inflammatory musculoskeletal features alongside skin/nail psoriasis, lacking specific criteria or tests.
  • Disease heterogeneity may stem from genetic factors, particularly within the HLA region.

Purpose of the Study:

  • To review the current understanding of psoriatic arthritis (PsA) diagnosis, heterogeneity, and treatment.
  • To highlight advancements in targeted therapies and their impact on patient outcomes.
  • To discuss the potential for personalized treatment approaches in PsA.

Main Methods:

  • Literature review of psoriatic arthritis (PsA) pathogenesis, diagnosis, and therapeutic advancements.
  • Analysis of clinical features, diagnostic challenges, and genetic influences in PsA.
  • Evaluation of current and emerging targeted therapies for PsA management.

Main Results:

  • Diagnosis of PsA involves recognizing inflammatory musculoskeletal signs in patients with psoriasis, typically without rheumatoid factor.
  • PsA exhibits significant heterogeneity in clinical presentation and progression, potentially linked to genetic variations.
  • Approved targeted therapies have improved musculoskeletal, skin, and radiographic outcomes in PsA patients.

Conclusions:

  • Despite diagnostic challenges, advancements in targeted therapies offer improved outcomes for psoriatic arthritis (PsA).
  • Understanding the molecular basis of PsA heterogeneity is crucial for developing personalized treatment strategies.
  • Further research into PsA's molecular underpinnings may enable tailored therapeutic approaches.
