Sex Linked Disorders01:43

Sex Linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
Adrenal Gland Disorders01:27

Adrenal Gland Disorders

Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
Cardiomyopathy II: Dilated Cardiomyopathy01:30

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
Genital Herpes01:23

Genital Herpes

Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Multiple Sclerosis l: Introduction01:19

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...

Area of Science:

  • Neuroimmunology
  • Neurology
  • Autoimmune Diseases

Background:

  • Multiple sclerosis (MS) is a primary inflammatory autoimmune disorder of the central nervous system.
  • It is a leading cause of neurological disability in young adults, with a lifetime risk of 1 in 400.
  • MS arises from complex interactions between genetic susceptibility and environmental factors.

Purpose of the Study:

  • To elucidate the cascade of events in multiple sclerosis pathogenesis.
  • To inform treatment strategies aimed at managing relapses, symptoms, and disease progression.
  • To explore how a deeper understanding of pathogenesis can improve clinical management.

Main Methods:

  • The study reviews the sequential processes involved in MS.
  • It examines the interplay of immune system engagement, inflammatory injury, repair, gliosis, and neurodegeneration.
  • Clinical course characterization based on these pathological events is discussed.

Main Results:

  • The pathogenesis involves immune system activation, acute inflammatory injury, functional recovery, gliosis, and neurodegeneration.
  • These processes explain the varied clinical presentations of MS, including relapses, persistent deficits, and secondary progression.
  • Current treatments aim to mitigate relapse frequency and severity, manage symptoms, and slow progression, with limited success.

Conclusions:

  • A comprehensive understanding of MS pathogenesis is crucial for developing more effective treatments.
  • Improved insights into the disease mechanisms are needed to enhance clinical management and patient outcomes.
  • Further research is necessary to translate pathogenic understanding into better therapeutic dividends for those affected by MS.
