Autoimmune Disorders01:29

Autoimmune Disorders

1.9K
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.

Nephrotic Syndrome II : Assessment and Medical Management

257
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...

T Cell Types and Functions01:24

T Cell Types and Functions

2.7K
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...

Nephrotic Syndrome I : Introduction

705
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Inflammatory Bowel Disease IV: Pharmacological Management

810
Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

Area of Science:

  • Immunology
  • Molecular Biology
  • Genetics

Background:

  • Systemic lupus erythematosus (SLE) pathogenesis involves complex immune system dysfunctions.
  • Understanding monogenic lupus-like diseases aids in characterizing SLE.
  • Aberrant immune functions in SLE are increasingly understood.

Purpose of the Study:

  • To review recent findings in SLE pathogenesis.
  • To highlight metabolic dysfunction, cytokine dysregulation, and signaling defects in SLE.
  • To discuss the role of DNA damage pathways in SLE.

Main Methods:

  • Review of recent scientific literature on SLE pathogenesis.
  • Focus on signaling pathways including mTOR, Rho kinase, BTK, and Ras.
  • Examination of DNA damage sensing and repair mechanisms.

Main Results:

  • Recent studies reveal metabolic dysfunction and cytokine dysregulation in SLE.
  • Signaling abnormalities in key pathways (mTOR, Rho kinase, BTK, Ras) are implicated.
  • DNA damage and repair pathway defects contribute to type I interferon overproduction in SLE.

Conclusions:

  • New findings deepen the understanding of broad immune dysfunction in SLE.
  • Dysregulated pathways identified in SLE offer potential therapeutic targets.
  • Existing and preclinical therapies may target these identified SLE pathways.
