Epidemiological studies have found that heavy alcohol use is associated with increased risk for Alzheimer's disease (AD), with frequent drinking earlier in adulthood increasing risk. The increases in neuroinflammation featured in both heavy alcohol use and AD may be partially responsible for this link. However, it is unknown if abstinence mitigates this risk.

Microglia in the neurogenic niche are important regulators of AHN, and ethanol promotes proinflammatory microglia activation.

Severe burn injury is a devastating trauma with significant immune dysfunction that results in an ∼12% mortality rate due to sepsis-induced organ failure, pneumonia, and other infections. Severe burn causes a biphasic immune response: an early (0-72 h) hyper-inflammatory state, with release of damage-associated molecular pattern molecules, such as high-mobility group protein 1 (HMGB1), and proinflammatory cytokines (e.

In conditions such as Alzheimer's or alcohol use disorder (AUD), Toll-like receptor (TLR) induction is observed with neurodegeneration. However, links between TLR activation and neurodegeneration are lacking.

Specifically, this study examines whether mean levels (as an indicator of organizational norms) of mentors' perceptions of their relationship quality with mentees' families predict mentor satisfaction, mentor intent to stay and mentor extra-role prosocial behavior over and above individual mentor perception of their relationship quality with mentees' families. Multilevel modeling was used to assess 204 mentors nested within 37 mentoring organizations.
