The aim of the present study was to examine the relationship between human β-defensin-2 (HBD-2), cathelicidin (LL-37) and upper respiratory tract infections (URTI). In addition, the possible association between salivary cortisol and the salivary antimicrobial peptides was also examined. We hypothesized that the saliva levels of HBD-2 and LL-37 are lower in elite marathon runners; and that saliva cortisol levels might have a negative association with saliva HBD-2 and LL-37.

The effect of 14 weeks of vitamin D3 supplementation on antimicrobial peptides and proteins in athletes

A daily 5000 IU vitamin D3 supplement has a beneficial effect in up-regulating the expression of SIgA and cathelicidin in athletes during a winter training period, which could improve resistance to respiratory infections.

A daily 5000 IU vitamin D3 supplement has a beneficial effect in upregulating the expression of SIgA and cathelicidin in athletes during a winter training period which could improve resistance to respiratory infections.

Upper Respiratory Tract Illness Incidence In Athletes: The Important Role Of Vitamin D

It can be concluded that athletes with low plasma vitamin D concentrations may have a higher risk of U RTI and suffer more severe symptoms when URTI is present and it was suggested that vitamin D3 supplementation could have a positive effect on immune function and lead to decreased incidence of respiratory infections.

Ageing and free-living daily physical activity effects on salivary beta-defensin 2 secretion

It is suggested that moderate physical activity in daily living improves age-related impairment of oral immune function mediated by hBD2 and for prevention of upper respiratory tract infections in elderly people, recommend accumulation of more than 7000 steps per day−1.

Effect of acupuncture stimulation on salivary human beta-defensin 2 after a single strenuous exercise in young male subjects

The results suggest that acupuncture treatment might contribute to improving the impairment of mucosal immune function mediated by hBD2 following intensive exercise.

What moderates salivary markers of inflammation reactivity to stress? A descriptive report and meta-regression

BMI may be important to examine when assessing salivary markers of inflammation in response to stress, and influence factors that influence these markers’ reactivity to stress is important.

The role of acetylation in the regulation of antimicrobial peptide gene expression in the human intestine

By the use of specific inhibitors of chromatin modifying enzymes, in an in vitro model of intestinal epithelial cells challenged with Escherichia coli strains, the importance of acetylation is discovered in the regulation of these genes, presenting a mechanism of (epi)genetic enhancement of AMPs expression, dissociated from the pro-inflammatory response.

Yoga Module to Improve Health and Wellbeing During COVID 19 Pandemic

A yoga package for improving immunity and other physical and physiological capacities and mental function to prevent Corona like disease has been formulated on the basis of knowledge from traditional yogic literature and evidence from available research publications on yoga.

Salivary IgA as a risk factor for upper respiratory infections in elite professional athletes.

The typical decline in an individual's relative s-IgA over the 3 wk before a URI appears to precede and contribute to URI risk, with the magnitude of the decrease related to the risk of URI, independent of the absolute s- IgA concentration.

Salivary levels of immunoglobulin A in triathletes.

The data suggest that the exercise of a triathlon may decrease the level of IgA-mediated immune protection at the mucosal surface, which may pose triathletes at an increased risk of infections.

Effects of 12 months of exercise training on salivary secretory IgA levels in elderly subjects

Regular moderate exercise seems to enhance mucosal immune function in elderly subjects, and both the concentration and secretion rate of SIgA significantly increased during 12 months of exercise in these elderly subjects.

Circadian effects on the acute responses of salivary cortisol and IgA in well trained swimmers

A significant circadian variation in the variables measured before exercise is suggested, without showing a significant effect on their acute responses to exercise.

Acute and chronic effects of exercise on markers of mucosal immunity.

The possible mechanisms underlying the acute and longer-term of effects of exercise on salivary responses are examined, with particular emphasis on the potential role of the sympathetic nervous system and the expression and mobilisation of the polymeric Ig receptor.

Ultramarathon running and upper respiratory tract infections. An epidemiological survey.

A relationship between acute stress and susceptibility to upper respiratory tract (URT) infections after a race is suggested and impairment of one or more local mucosal or general host defences may account for this effect.

Upper respiratory tract infection in athletes: influence of lifestyle, type of sport, training effort, and immunostimulant intake.

A short review on the literature dealing with URTI in athletes with special reference to lifestyle factors, the coping with daily stress, and dietary behavior are important cofactors in the immune response to exercise.

Expression and activity of beta-defensins and LL-37 in the developing human lung.

HBD-2 was found to be the predominant beta-defensin in human neonatal lung and HBD-3 and LL-37 messages were not detected in airway epithelial cultures, and each antimicrobial peptide exhibited a unique spectrum of antimicrobial activity and salt sensitivity against bacteria commonly causing sepsis in the neonate.

Tennis, incidence of URTI and salivary IgA.

Investigation of the temporal association between specific components of tennis training and competition, the incidence of upper respiratory tract infections (URTI), and salivary IgA in a cohort of seventeen elite female tennis players showed that higher incidence of URTI was significantly associated with increased training duration and load, and competition level, on a weekly basis.
