Human rhinovirus 16 (HRV16) may induce inflammatory and antiviral responses in the human lung vascular endothelium (ECs) and impair its barrier functions after infection. However, ECs may regain barrier and metabolic functions. Mechanisms of limitation of HRV16 infection in the lung vascular endothelium are unknown. Human lung vascular endothelium (HMVEC-L) was infected with HRV16. IFN-β, OAS-1, and PKR expression was assessed by real-time PCR, flow cytometry, and confocal microscope. To prove the significance of IFN-β in the limitation of HRV16 replication, HMVEC-Ls were preincubated with anti-IFN-β Abs. To prove the involvement of OAS-1 and PKR in the IFNdependent limitation of HRV16 replication, HMVEC-Ls were transfected with respective siRNA. HRV16 stimulated IFN-β production and activated intracellular mechanisms of antiviral immunity based on OAS-1 and PKR activation. Blocking of IFN-β contributed to the inhibition of intracellular mechanisms of antiviral immunity (OAS-1, PKR) and boosted replication of HRV16. Effective OAS-1 silencing by siRNA caused the increase of HRV16 copy numbers after HRV16 infection. siRNA upregulated the other genes related to the antiviral response. The infected lung vascular endothelium may limit the HRV16 infection. This limitation may be associated with the induction of IFN-β-dependent intracellular mechanisms based on OAS-1 and PKR activity.

INTRODUCTION AND AIM OF WORK One of the key factors shaping human health is diet. It serves as the foundation for the functioning of cells, organs, and the entire body. Properly chosen food has an impact, among other things, on the functioning of the immune, digestive, and cardiovascular systems. MATERIALS AND METHODS The objective of this study is to analyze the changes in the functioning of the cardiovascular, digestive, and immune systems through the application of different dietary approaches. For this purpose, an original questionnaire was developed. The questionnaire was distributed via social media (Telegram platform) in August 2023 among the population of Ukraine. RESULTS We collected a total of 94 surveys, with an average participant age of 26 years. A similar number of participants indicated consuming meals 3 times, 4 times, or 5 times a day. These were 23 individuals (24.47%), 25 individuals (26.6%), and 21 individuals (22.3%) respectively. The analysis of correlations revealed a negative correlation between the frequency of meal consumption and the frequency of infections (r = -0.21, p = 0.035). A significant relationship was also observed between body weight and the frequency of meal consumption (r = 0.34, p < 0.001). However, no significant relationship was found between following a special diet and body weight (p > 0.05). CONCLUSIONS The collected results suggest a connection between dietary habits and the frequency of infections as well as body weight. Interestingly, this relationship was related specifically to the frequency of meal consumption and was not linked to the intake of specific food groups. The obtained results highlight the significance of regular meal consumption in maintaining a healthy body weight and reducing the frequency of infections. [ABSTRACT FROM AUTHOR]
