Layers of Connective Tissue Proper01:21

Layers of Connective Tissue Proper

8.4K
Fascia, a thin layer of fibrous connective tissue, is distributed throughout the body. It demarcates and forms a supportive covering over skeletal muscles, bones, blood vessels, and organs. There are three main types of facia— superficial fascia, deep fascia, and subserous fascia. These are all present at different depths in the body. Fascia reduces the friction and permits muscles, joints, and organs to easily slide against each other, facilitating movement of the body and preventing...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

2.4K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Cystic Fibrosis: Pathogenesis

1.1K
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

950
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Rheumatic Heart Disease I: Introduction

970
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...

Cardiomyopathy IV: Restrictive Cardiomyopathy

909
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

Area of Science:

  • Rheumatology
  • Immunology
  • Fibrosis Research

Background:

  • Systemic sclerosis (SSc) is a fibrotic disorder characterized by autoimmunity and vasculopathy preceding fibrosis.

  • Existing immunomodulatory therapies for SSc have not effectively reversed or halted disease progression.

Purpose of the Study:

  • To review recent studies on the cellular and molecular mechanisms of fibrosis in SSc.
  • To identify potential novel therapeutic targets for SSc based on underlying fibrotic processes.

Main Methods:

  • Review of current scientific literature on systemic sclerosis.
  • Analysis of cellular and molecular pathways involved in SSc-related fibrosis.

Main Results:

  • Recent studies offer insights into the mechanisms driving fibrosis in SSc.
  • Specific cellular processes and proteins have been identified as potential therapeutic targets.

Conclusions:

  • Understanding the mechanisms of fibrosis in SSc is crucial for developing effective treatments.
  • Targeting identified cellular processes and proteins may offer new therapeutic strategies for this multisystemic fibrotic disease.
