Export of Misfolded Proteins out of the ER01:32

Export of Misfolded Proteins out of the ER

4.7K
After folding, the ER assesses the quality of secretory and membrane proteins. The correctly folded proteins are cleared by the calnexin cycle for transport to their final destination, while misfolded proteins are held back in the ER lumen. The ER chaperones attempt to unfold and refold the misfolded proteins but sometimes fail to achieve the correct native conformation. Such terminally misfolded proteins are then exported to the cytosol by ER-associated degradation or ERAD pathway for...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

4.2K
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,...

Personality Disorders: Schizotypal and Histrionic

267
Schizotypal personality disorder and histrionic personality disorder are two distinct psychological conditions classified under personality disorders, each characterized by unique behavioral patterns and social difficulties. Both disorders significantly affect interpersonal relationships and emotional well-being, leading to social isolation and frustration.

Cardiomyopathy III: Hypertrophic Cardiomyopathy

153
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Classification of Illness01:17

Classification of Illness

8.3K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Prosopagnosia01:24

Prosopagnosia

542
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

  • Audiology
  • Dentistry
  • Cell Biology

Background:

  • Heimler syndrome is a rare genetic disorder characterized by sensorineural hearing loss, retinal dystrophy, and amelogenesis imperfecta.
  • It is caused by biallelic pathogenic variations in the PEX1 or PEX6 genes.
