Sleep has been proposed as an innate host defense, exerting effects on both specific and nonspecific immunity. In one of the more striking papers dealing with the effects of sleep on specific immunity, Brown et al (Reg. Immunol. 1989; 2: 321-325) reported that depriving influenza virus-immune mice of sleep for 7 hours following total respiratory tract viral challenge abrogated anti-viral immunity within the lungs and lowered the level of anti-influenza antibody in lung homogenates. In the solidly-immune convalescent mouse, nasobronchial immunity to influenza virus has been shown to be due to secretory IgA (S-IgA) within the mucosal mucocilliary blanket, while serum IgG has been shown to mediate protection within the lung parenchyma. In this study we attempted to duplicate the work of Brown et al in solidly immune mice. We were unable to abrogate mucosal anti-influenza viral immunity with a single post-viral-challenge sleep-deprivation episode, nor were we able to depress this immunity with one pre- and two post-challenge sleep-deprivation episodes in young adult or old mice, or with two pre-challenge sleep-deprivation episodes in old mice. Sleep deprivation did not depress the level of serum influenza-specific IgG antibodies, and resulted in increased influenza-specific serum IgG compared with normally sleeping mice in aged immune mice boosted 3 weeks before challenge and sleep deprived once before and twice after challenge (p = 0.005). No differences in anti-viral respiratory immunity were apparent between young and old mice. We conclude that short-term sleep deprivation has minimal effects on pre-existing mucosal and humoral immunity in either the young adult or the senescent mouse.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 May 2020.
All research outputs
#22,764,772
of 25,382,440 outputs
Outputs from Sleep
#4,296
of 4,560 outputs
Outputs of similar age
#32,622
of 33,410 outputs
Outputs of similar age from Sleep
#10
of 10 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,560 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 32.4. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 33,410 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 10 others from the same source and published within six weeks on either side of this one.
