Lysosomal Hydrolases01:22

Lysosomal Hydrolases

3.8K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Smooth Endoplasmic Reticulum01:21

Smooth Endoplasmic Reticulum

5.7K
Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

145
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Alzheimer's Disease: Overview01:26

Alzheimer's Disease: Overview

451
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Renal Tubule and Collecting Duct01:24

Renal Tubule and Collecting Duct

850
The renal tubule is divided into three parts: the proximal convoluted tubule (PCT), the Loop of Henle (LOH), and the distal convoluted tubule (DCT).
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...

Parkinson's Disease: Overview01:15

Parkinson's Disease: Overview

495
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Area of Science:

  • Genetics
  • Metabolic Disorders
  • Neurology

Background:

  • X-linked adrenoleukodystrophy (ALD) is a peroxisomal disorder stemming from ABCD1 gene mutations.
  • It impairs very long-chain fatty acid beta-oxidation, leading to progressive neurological and adrenal complications.

Purpose of the Study:

  • To provide a detailed discussion of the clinical spectrum of X-linked adrenoleukodystrophy.
  • To outline the variability in disease onset and progression in affected individuals.

Main Methods:

  • Review of existing literature and clinical data on X-linked adrenoleukodystrophy patients.
  • Analysis of clinical manifestations, including adrenal failure, myelopathy, and cerebral involvement.

Main Results:

  • ALD presents with variable clinical phenotypes in males, including adrenal failure and progressive myelopathy.
  • Cerebral ALD affects 40% of males before age 18; women typically experience milder, later-onset myelopathy.
  • Hematopoietic cell transplantation can halt cerebral ALD progression, but myelopathy lacks a curative treatment.

Conclusions:

  • The clinical spectrum of ALD is diverse, necessitating tailored management strategies.
  • Understanding the variability in ALD progression is crucial for patient care and therapeutic development.
