METH and HIV Tat treatment results in increased oxidative stress which affects cellular metabolism and causes DNA damage in the treated microglia. Both, METH ± HIV Tat impair mitochondrial respiration, leading to dysfunction in bioenergetics and increased ROS in microglial cells. Our data indicate that mitochondrial dysfunction may be key to the METH and/or HIV Tat-induced neuropathology. METH and/or HIV Tat induced changes in the protein, lipid and nucleotide concentration in microglial cells were measured by Raman Spectroscopy, and we speculate that these fundamental molecular-cellular changes in microglial cells contribute to the neuropathology that is associated with METH abuse in HIV patients.

p62 Binding to Protein Kinase C Regulates HIV-1 gp120 V3 Loop Induced Microglial Inflammation.

The main pathogenic mechanism of HIV-associated neurocognitive disorders (HAND) is neuronal apoptosis induced by inflammatory mediators, in which microglial inflammation plays a crucial role. However, the exact pathogenic mechanism remains unclear. Previous studies have shown that the HIV-1 gp120 V3 loop can trigger inflammation in CHME-5 microglia.

Microglia are highly specialized resident macrophages in the central nervous system that play a pivotal role in modulating neuroinflammation. Microglial plasticity is essential for their function, allowing them to polarize into proinflammatory M1-like or anti-inflammatory M2-like phenotypes. However, the mechanisms driving M1 and M2 microglial induction during retinal degeneration remain largely unexplored.

Colony-stimulating factor-1-receptor (CSF1R) inhibitors have been widely used to rapidly deplete microglia from the brain, allowing the remaining microglia population to self-renew and repopulate. These new-born microglia are thought to be "rejuvenated" and have been shown to be beneficial in several disease contexts and in normal aging. Their role in Alzheimer's disease (AD) is thus of great interest as they represent a potential disease-modifying therapy.

The remyelination process within the diabetes mellitus (DM) brain is inhibited, and dynamic interactions between DNA methylation and transcription factors are critical for this process. Repressor element-1 silencing transcription factor (REST) is a major regulator of oligodendrocyte differentiation, and the role of REST on DM remyelination remains to be investigated. Here, we investigated the effects of REST and DNA methylation on DM remyelination and explored the underlying mechanisms.

Exposure to Perinatal Trauma Modifies Nociception and Gene Expression in the Prefrontal Cortex and Hypothalamus of Adolescent Rats.

The perinatal period encompasses a critical window for neurodevelopment that renders the brain highly responsive to experience. Trauma, such as intimate partner violence (IPV) and early life stress/neglect, during this period negatively affects physical and mental health outcomes, including increasing ones risk for chronic pain. Although epigenetic programming likely contributes, the mechanisms that drive the relationship between perinatal trauma and adverse health outcomes, are not fully understood.
