VDR mRNA Expression And Serum Vitamin D Levels in Post-Covid Vaccinated Patients

Abstract

The emergence of COVID-19 vaccines has reshaped the trajectory of the ongoing pandemic, offering hope for widespread immunity. Beyond conferring protection against SARS-CoV-2, these vaccines have exhibited intriguing immunomodulatory effects. This research explores the dynamic interplay among VDR mRNA expression levels, calcium (ionized and total), and intact parathyroid hormone (iPTH) concentrations in individuals post-COVID-19 vaccination. The Vitamin D Receptor (VDR) plays a pivotal role in immune regulation and is closely intertwined with calcium homeostasis. This study investigates the hypothesis that COVID-19 vaccination may induce alterations in VDR mRNA expression, subsequently influencing calcium metabolism and iPTH secretion. Our findings reveal dynamic shifts in VDR mRNA expression following COVID-19 vaccination, with distinct patterns observed across individuals. Concurrently, we observe ionized and total calcium levels alterations, hinting at potential links between VDR activity and calcium metabolism post-vaccination. Furthermore, iPTH levels exhibit intriguing fluctuations, suggesting a regulatory role of VDR in parathyroid hormone secretion. The integration of clinical outcomes and vaccine response data sheds light on the significance of these molecular and biochemical alterations. This research underscores the multifaceted impact of COVID-19 vaccination on VDR mRNA expression, calcium homeostasis, and iPTH regulation. Beyond the scope of vaccination, our findings may bear implications for immunomodulation in various disease contexts, particularly in individuals with pre-existing calcium-related disorders. In conclusion, our study unveils the intricate relationships among VDR mRNA expression, calcium levels, and iPTH concentrations in the context of post-COVID-19 vaccination. These discoveries extend our understanding of vaccine-induced immunomodulation and may pave the way for personalized vaccination strategies, while also opening new avenues for investigating the role of VDR in immune responses and calcium regulation beyond the pandemic.
