T Cell Types and Functions01:24

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

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...
Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

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...
Inflammatory Bowel Disease II: Ulcerative Colitis01:20

Inflammatory Bowel Disease II: Ulcerative Colitis

Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
Inflammatory Bowel Disease III: Crohn's Disease01:25

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Area of Science:

  • Dermatology
  • Vascular Biology
  • Immunology

Background:

  • Vascular endothelial cells (ECs) form the inner lining of blood vessels.
  • Previously viewed as passive, ECs are now known to actively regulate vascular function and skin inflammation.
  • Specific EC subtypes play critical roles in various skin physiological and pathological processes.

Purpose of the Study:

  • To review the role of ECs in skin inflammation and psoriasis.
  • To explore EC dysfunction as a factor in psoriasis pathogenesis.
  • To identify potential therapeutic targets within dysregulated EC pathways for psoriasis treatment.

Main Methods:

  • Literature review of recent studies on endothelial cell biology and dermatology.
  • Analysis of the role of EC subtypes in skin homeostasis and disease.
  • Synthesis of evidence linking EC dysfunction to psoriasis development and progression.

Main Results:

  • ECs are active participants in regulating vascular function and immune responses in the skin.
  • Evidence suggests EC dysfunction is both a cause and consequence in psoriasis pathogenesis.
  • Specific dysregulated pathways in ECs are implicated in the disease.

Conclusions:

  • Endothelial cell dysfunction is central to the pathogenesis of psoriasis.
  • Targeting dysregulated EC pathways offers promising therapeutic strategies for psoriasis.
  • Further research into EC biology in psoriasis is warranted.
