Does alcohol help a cold? Benefits, risks, and remedies

Specifically, 24 hours of exposure to both low (1mM) and high (5mM) concentrations of acetaldehyde stimulate IL-6 secretion, however, 7 days of exposure to the high concentration of acetaldehyde, significantly decrease IL-6 secretion (Sarc, Wraber et al. 2011). In contrast, both acute (24 hours) and prolonged (7 days) exposure to low and high concentrations of acetaldehyde reduce TNF-α secretion by primary rat astrocyte (Sarc, Wraber et al. 2011). Much progress has been made in elucidating the relationship between alcohol consumption and immune function and how this interaction affects human health. Normal immune function hinges on bidirectional communication of immune cells with nonimmune cells at the local level, as well as crosstalk between the brain and the periphery. These different layers of interaction make validation of the mechanisms by which alcohol affects immune function challenging.

This reduced class I MHC expression can result from infection with certain types of viruses. Several lines of evidence suggest that alcohol consumption exerts a dose-dependent impact on the host response to infection. Chronic alcohol abuse leads to increased susceptibility to bacterial and viral infections, most notably a 3 to 7-fold increase in susceptibility (Schmidt and De Lint 1972) and severity (Saitz, Ghali et al. 1997) of bacterial pneumonia compared with control subjects.

Alcohol’s Burden on Immunity Following Burn, Hemorrhagic Shock, or Traumatic Brain Injury

Leclercq thinks that 30–40% of cases of AUD might have a gut-related component that could be targeted for treatment. A key challenge is determining exactly which components to target — it is as yet unclear what constitutes a ‘good’ microbiome. Day’s analysis does alcohol suppress immune system suggests that bacteria such as Lactobacillus, were in abundance in people with AUD, whereas Akkermansia and some others were low. In 2023, Kiraly and his colleagues looked at whether rats’ microbiomes affected the animal’s drug-seeking behaviours4.

  • In addition, alcohol markedly affects the differentiation of dendritic cells in blood and tissues (Ness et al. 2008).
  • The complexity of the innate and adaptive immune responses are increased further by the fact that different subsets of immune cells may reside in specific organs, such as the liver, lungs, brain, skin, bones, or muscles.
  • Like many people, you may still want to enjoy alcohol without compromising your immune system.
  • The first point of contact for alcohol after consumption is the gastrointestinal (GI) system before it is absorbed into the bloodstream.

Such studies can be challenging to conduct in humans because of difficulties in obtaining accurate medical histories, maintaining adherence, confounding factors such as diet, sleep-wake cycles, and ethical considerations when studying large doses of ethanol. Rodent studies offer several advantages such as availability of transgenic models that can facilitate mechanistic studies. Rodents have a much shorter life span and often require forced (i.e., not initiated by the animal) exposure to alcohol, which is stressful. Moreover, a recent systematic comparison examining gene expression changes found that temporal gene response patterns to trauma, burns, and endotoxemia in mouse models correlated poorly with the human conditions (Seok, Warren et al. 2013). Nonhuman primates, on the other hand, voluntarily consume different amounts of alcohol and allow us to conduct studies in an outbred species that shares significant physiological and genetic homology with humans while maintaining rigorous control over diet and other environmental cues.

Type of Alcohol

Upon LPS binding, monocytes become activated, mature into macrophages and migrate into tissues where they respond to infection by secreting various cytokines, recruiting additional leukocytes via production of chemokines and presenting pathogen-derived peptides to T cells to activate them. Often, investigators stimulate with LPS after pre-exposure to ethanol to mimic inflammation observed in trauma patients with high blood alcohol levels and explore the alterations in immunity that lead to frequent subsequent infections among this group. DCs, which are the major cell type linking the innate and adaptive immune response, also are affected by alcohol intoxication.

  • Leclercq thinks that 30–40% of cases of AUD might have a gut-related component that could be targeted for treatment.
  • Potential intracellular target points for (i) acute alcohol and (ii) chronic alcohol in a stylized cell.
  • For example, while acute high-level exposure to ethanol inhibits proinflammatory cytokine production, long-term moderate administration of ethanol stimulates the process.
  • There is some evidence that drinking a small amount of alcohol may reduce the number of colds people get per year.
  • In addition, in vivo consumption of moderate amounts enhances phagocytosis and reduces inflammatory cytokine production whereas chronic consumption of large doses inhibits phagocytosis and production of growth factors.

In one experiment, rats were given either clean water or water containing the antibiotics neomycin, vancomycin, bacitracin and pimaricin, all of which would deplete their gut microbiota. They were then let into a chamber in which they could push a lever that lit up and provided 0.8 milligrams of cocaine. Later, researchers altered how the lever behaved — now it would light up when pushed, but would have to be pushed more times for the rats to receive cocaine.
