T Cell Types and Functions

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...

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

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...
Myasthenia Gravis ll: Pathophysiology01:22

Myasthenia Gravis ll: Pathophysiology

The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...

Summary

Multiple sclerosis (MS) involves CNS inflammation, demyelination, and axon loss, driven by T(H)1 T cells. New therapies are needed to promote remyelination and neuroprotection, addressing irreversible axon damage and long-term disability.

Area of Science:

  • Neuroimmunology
  • Central Nervous System (CNS) Disorders
  • Autoimmune Diseases

Background:

  • Multiple sclerosis (MS) is an immune-mediated CNS disease.
  • Characterized by inflammation, demyelination, and axon loss.
  • Inflammation is linked to an overactive pro-inflammatory T(H)1 T cell profile.

Purpose of the Study:

  • To summarize the pathological hallmarks of MS.
  • To highlight the limitations of current FDA-approved treatments.
  • To identify the need for novel therapeutic strategies.

Main Methods:

  • Review of existing literature on MS pathogenesis.
  • Analysis of the mechanisms of inflammation, demyelination, and axon loss.
  • Evaluation of the efficacy of current MS therapies.

Main Results:

  • MS involves inflammation, demyelination, and early axon loss.
  • Current treatments are most effective during the inflammatory phase.
  • Axon loss is irreversible and contributes to long-term disability.

Conclusions:

  • Existing MS therapies primarily target inflammation.
  • There is a critical need for therapies promoting remyelination.
  • Neuroprotective strategies are essential to prevent irreversible axon damage and disability in MS.
