Rabies

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...

Arboviral Encephalitis

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Cryptococcal Meningitis

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 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 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...

Alzheimer Disease ll: Pathophysiology

Alzheimer Disease ll: Pathophysiology

Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...

Summary

AIDS dementia complex (ADC), a common neurologic issue in acquired immunodeficiency syndrome (AIDS), results from HIV-1 CNS infection. Indirect mechanisms, like immune responses and neurotoxins, contribute to ADC and sensory neuropathy.

Area of Science:

Neurology
Immunology
Virology

Context:

Acquired immunodeficiency syndrome (AIDS) frequently presents with neurologic complications, notably AIDS dementia complex (ADC), also known as HIV encephalopathy.
While HIV-1 directly infects the central nervous system (CNS), the widespread pathology in ADC suggests indirect or immunopathogenetic mechanisms are at play.
HIV-1-associated sensory neuropathy is also a significant concern in AIDS patients.

Purpose:

To explore the underlying mechanisms of AIDS dementia complex (ADC) and HIV-1-associated sensory neuropathy.
To investigate the potential indirect and immunopathogenetic pathways contributing to neurological damage in HIV-1 infection.
To elucidate the role of specific molecular and cellular interactions in HIV-1-induced neurotoxicity.

AIDS dementia complex (ADC) is the most common neurologic disease in AIDS, stemming from HIV-1 infection of the CNS.
Limited HIV-1 expression in CNS/PNS contrasts with widespread abnormalities, suggesting indirect pathogenic mechanisms.
Proposed mechanisms include oligodendrocyte injury by TNF-alpha, gp120-induced excitotoxicity, NMDA receptor-mediated neurotoxicity by quinolinic acid, cytotoxic T cell injury, and apoptosis.
Cytokine networks and macrophage-neural cell interactions via adhesion molecules amplify neurotoxic effects.

Impact:

Understanding these mechanisms is crucial for developing targeted therapies to prevent or treat HIV-1-associated neurological disorders.
This research highlights the complex interplay between the immune system and the CNS in the context of HIV-1 infection.
Identifying key molecular players like TNF-alpha, gp120, and quinolinic acid offers potential therapeutic targets for neuroprotection in AIDS patients.
