Studies also have analyzed the role of GM-CSF in alcohol-induced oxidative stress and impaired lung immunity. GM-CSF is secreted by type II alveolar cells and is required for terminal differentiation of circulating http://seaman-sea.ru/tankera/599-podgotovka-tankera-k-proverke.html monocytes into mature, functional alveolar macrophages (Joshi et al. 2006). The levels of GM-CSF are reduced in chronic alcohol-drinking mice (Joshi et al. 2005). Chronic alcohol intake also decreased alveolar binding of PU.1, a transcription factor responsible for GM-CSF activation.
Cancer risk
- Although you may experience some enjoyable effects from alcohol, you are likely aware of the potential harm over-consumption can do to your body.
- When you drink too much alcohol, it can throw off the balance of good and bad bacteria in your gut.
- As with most things in life, the arrow points to “moderation” (unless you are in a high-risk group due to poor health or pregnancy).
- Women drinking fewer than two drinks at a time and men drinking fewer than three drinks at a time is considered moderate drinking.
- Over the past two decades, studies demonstrated that brief exposure to modest alcohol concentrations triggers generation of nitric oxide (NO) in the airway epithelial cells.
- Stopping alcohol use can significantly improve your health, boost your immune system and protect your body from serious infections and viruses.
Some of http://forum-abkhazia.ru/showthread-t_1454-page_9.html this discrepancy likely is related to differences in the bacterial pathogens studied. Thus, Jareo and colleagues (1995) noted impaired neutrophil killing of selected strains of S. Pneumoniae in vitro and a complete absence of killing of other bacterial strains in alcohol-exposed animals. In human studies, BACs as low as 0.2 percent (i.e., approximately 2.5 times the legal intoxication level) impaired neutrophil degranulation and bactericidal activity (Tamura et al. 1998).
Preventing Immune System Damage
As mentioned previously, alveolar macrophages are key components of both innate and acquired immunity against invading pathogens in the lung. After mucociliary clearance, these cells are the next line of cellular defense against invading pathogens through their phagocytic, microbiocidal, and secretory functions (Rubins 2003). Chronic alcohol ingestion decreases alveolar macrophage function by inhibiting the release of cytokines and chemokines as well as other factors essential for microbial killing and immune response (Franke-Ullmann et al. 1996; Omidvari et al. 1998). Alcohol-induced alveolar macrophage dysfunction likely occurs primarily as a result of alcohol-induced increases in oxidative stress, which is reflected by depletion of the antioxidant glutathione (GSH) in BAL fluid (Brown et al. 2007; Yeh et al. 2007). Impaired secretion of granulocyte monocyte colony-stimulating factor (GM-CSF) by type II alveolar cells likely also contributes to alcohol-induced oxidative stress (Joshi et al. 2005). The identification of alcohol-driven oxidative stress as a contributor to alveolar macrophage dysfunction has led to promising antioxidant treatment approaches aiming to prevent alcohol-induced lung conditions in rodent models of prolonged alcohol consumption.
