Alcohol and inflammation and immune responses: summary of the 2005 Alcohol and Immunology Research Interest Group (AIRIG) meeting.

The 10th annual meeting of the Alcohol and Immunology Research Interest Group (AIRIG) was held at Loyola University Medical Center, Maywood, Illinois on November 18, 2005. The AIRIG meeting was held to exchange new findings and ideas regarding the profound suppressive effects of alcohol exposure on the immune system. The event consisted of five sessions, two of which featured plenary talks from invited speakers, two with oral presentations from selected abstracts, and a final poster session. Participants presented a range of novel information focused on ethanol-induced effects on innate and adaptive immunity after either acute or chronic exposure. In particular, participants offered insights into the negative effects of ethanol on the innate processes of adhesion, migration, inflammation, wound repair, and bone remodeling. Presentations also focused on the means by which ethanol disrupts activation of macrophages and dendritic cells (DC), especially stimulation mediated by Toll-like receptor ligands. Additional talks provided new data on the means by which ethanol suppresses adaptive immunity, with an emphasis on DC-mediated activation of T cells, effector T cell activity, and T cell-driven B cell responses.
