Autoimmune Disorders

Autoimmune Disorders

Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Neural Regulation

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.

Neurogenesis and Regeneration of Nervous Tissue

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Parkinson's Disease: Overview

Parkinson's Disease: Overview

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...

Disorders of the Nervous Tissue

Disorders of the Nervous Tissue

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...

Background:

Lewy body dementia (LBD) is a progressive neurodegenerative disorder characterized by cognitive decline, parkinsonism, and visual hallucinations.
The underlying pathophysiology of LBD is not fully understood, but neuroinflammation is increasingly recognized as a significant factor.

Purpose of the Study:

To investigate the role of a specific adaptive immune signaling axis in the context of Lewy body dementia pathology.
To identify potential therapeutic targets within this axis for LBD treatment.

Main Methods:

Analysis of immune cell populations and cytokine profiles in LBD patient samples.
In vitro and in vivo models to assess the impact of the signaling axis on neuronal health and protein aggregation.

Main Results:

The study identified dysregulation of a critical adaptive immune signaling axis in LBD.
Specific components of this axis were found to correlate with disease severity and alpha-synuclein pathology.

Conclusions:

The investigated adaptive immune signaling axis represents a novel and potentially druggable target for Lewy body dementia.
Modulating this pathway could offer a new therapeutic strategy to slow or halt LBD progression.
