Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders01:27

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

2.3K
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

EPS and iPS Cells in Disease Research

3.5K
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Postsynaptic Potential (PSP)01:32

Postsynaptic Potential (PSP)

7.1K
Postsynaptic potential (PSP) refers to a change in the electrical potential of a neuron when neurotransmitters released by presynaptic neurons bind to postsynaptic receptors. This potential can either be excitatory, leading to depolarization and ultimately action potential generation, or inhibitory, leading to hyperpolarization and suppression of the postsynaptic neuron.
There are two types of receptors: ionotropic and metabotropic.
The ionotropic receptor is the membrane protein that has an...

T Cell Types and Functions01:24

T Cell Types and Functions

3.0K
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...

Parkinson's Disease: Overview

2.3K
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...

    Summary

    Histopathology of nervous tissue in psoriasis vulgaris showed no abnormal changes. This study examined skin lesions and unaffected skin using three distinct stains.

    Area of Science:

    • Dermatology
    • Neuropathology
    • Histopathology

    Background:

    • Psoriasis vulgaris is a chronic inflammatory skin condition.
    • Nervous system involvement in psoriasis is an area of ongoing research.
    • Understanding the histopathological changes in skin is crucial for psoriasis management.

    Purpose of the Study:

    • To investigate the histopathology of nervous tissue elements in psoriasis vulgaris lesions.
    • To compare the nervous tissue in affected and unaffected skin of patients with psoriasis vulgaris.
    • To determine if specific stains reveal any abnormalities in nerve structures.

    Main Methods:

    • Histopathological examination of skin biopsies from psoriasis vulgaris patients.
    • Utilized three distinct staining techniques to visualize nervous tissue.

  • Analyzed both lesional and uninvolved skin samples.

    • Main Results:

    • No significant abnormal changes were detected in the nervous tissue elements.
    • Histopathology revealed no discernible differences between lesional and uninvolved skin regarding nerve structures.
    • The applied stains did not highlight any pathological alterations in the nerve components.

    Conclusions:

    • The study found no evidence of nervous tissue abnormalities in psoriasis vulgaris skin.
    • Histopathological analysis using three stains did not reveal neuropathological changes.
    • Further research may be needed to fully elucidate the role of nervous tissue in psoriasis pathogenesis.
