亜急性硬化性汎頭炎における麻疹ウイルスに特異的な免疫グロブリン-M応答
Lancet (London, England)
|February 12, 1977
まとめ
亜急性硬化性汎頭炎 (SSPE) の患者は,血清と脳脊髄液 (CSF) で高濃度の麻疹特異IgMとIgG抗体を示しています. 増加したCSFのIgMは,局所抗体生成を示唆し,中枢神経系における麻疹ウイルスの持続を示唆する.
科学分野:
- 神経学 神経学とは
- 免疫学 免疫学とは
- ウイルス学 ウイルス学 ウイルス学
背景:
- 亜急性硬化性脳膜炎 (SSPE) は,麻疹ウイルス感染症の希少で致命的な神経学的合併症です.
- 中枢神経系 (CNS) で持続する麻疹ウイルスは,SSPEの病原性に関与しています.
研究 の 目的:
- 麻疹ウイルスに特異的なIgMおよびIgG抗体応答をSSPE患者で調査する.
- 脳脊髄液 (CSF) のIgM値上昇が,中枢神経系のウイルスの持続性を示すかどうかを判断する.
主な方法:
- 20人のSSPE患者と2つの対照群からの血清とCSFサンプルを分析するために,間接的な放射性免疫測定法を使用しました.
- 麻疹に特異的なIgMとIgG抗体タイターの定量化.
主要な成果:
- すべてのSSPE患者は,高血清およびCSF抗麻疹抗体位数 (IgMおよびIgG) を示した.
- SSPE症例の35%で,IgM応答は血清よりもCSFで高かったため,内IgM生成が示唆された.
- コントロールグループは,血清またはCSFで特定のIgM応答を示さなかった.
結論:
- SSPE患者の血清とCSFにおける高濃度の麻疹特異性IgMとIgGは,強い免疫反応を確認しています.
- SSPE患者におけるCSF固有のIgM抗体の上昇は,中枢神経系内での麻疹ウイルスの持続性を示している.
- CSFにおけるウイルス特異的なIgMの検出は,慢性の中枢神経系のウイルスの持続性のバイオマーカーとして機能する可能性があります.

Immune Response Against Viral Pathogens
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
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...
