Alzheimer-Type Cerebral Amyloidosis in the Context of HIV Infection: Implications for a Proposed New Treatment Approach.

Reverse transcriptase inhibitors (RTIs) are currently broadly prescribed for the treatment of HIV infection but are also thought to prevent Alzheimer's disease (AD) progression by protecting against amyloidosis. Our study evaluates the hypothesis that reverse transcriptase inhibitors protect against Alzheimer-type brain amyloidogenesis in the context of HIV infection. We compiled a case series of participants from a prospective study of the neurological consequences of HIV infection at the HIV Neurobehavioral Research Program (HNRP) who had serial neuropsychological and neurological assessments and were on RTIs.

Behavioral and histological assessment of a novel treatment of neuroHIV in humanized mice.

Unlabelled: Neurocognitive deficits are prevalent among people living with HIV, likely due to chronic inflammation and oxidative stress in the brain. To date, no pharmaceutical treatments beyond antiretroviral therapy (ARV) has been shown to reduce risk for, or severity of, HIV-associated neurocognitive disorder. Here we investigate a novel compound, CDDO-Me, with documented neuroprotective effects via activation of the nrf2 and inhibition of the NFkB pathways.

The relationship between synaptodendritic neuropathology and HIV-associated neurocognitive disorders is moderated by cognitive reserve.

We examined whether cognitive reserve moderated the relationship between neurodegeneration and cognition in 67 postmortem persons with HIV (PWH) who were cognitively assessed within 1 year of death. Cognitive reserve was measured via the Wide Range Achievement Test-4 reading subtest (WRAT4). Synaptodendritic neurodegeneration was based on densities of synaptophysin and microtubule-associated protein 2 immunohistochemical reactivity in frontal cortex, and categorized as minimal, moderate, or severe (tertile-split).

GPR120/FFAR4 stimulation attenuates airway remodeling and suppresses IL-4- and IL-13-induced airway epithelial injury via inhibition of STAT6 and Akt.

Background: Airway remodeling is associated with severity and treatment insensitivity in asthma. This study aimed to investigate the effects of G protein-coupled receptor 120 (GPR120) stimulation on alleviating allergic inflammation and remodeling of airway epithelium.

Research Design And Methods: Ovalbumin (OVA)-challenged BALB/c mice and type-2-cytokine (IL-4 and IL-13)-exposed 16HBE human bronchial epithelial cells were treated with GSK137647A, a selective GPR120 agonist.
