The effects of prolactin on the immune system, its relationship with the severity of COVID-19, and its potential immunomodulatory therapeutic effect. Cytokine 2023; 169:156253. [PMID: 37320963 PMCID: PMC10247151 DOI: 10.1016/j.cyto.2023.156253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 05/01/2023] [Accepted: 05/31/2023] [Indexed: 06/17/2023]
Abstract
Prolactin (PRL) is an endocrine hormone secreted by the anterior pituitary gland that has a variety of physiological effects, including milk production, immune system regulation, and anti-inflammatory effects. Elevated levels of PRL have been found in several viral infections, including 2019 coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), a viral pathogen that has recently spread worldwide. PRL production is increased in SARS-CoV2 infection. While PRL can trigger the production of proinflammatory cytokines, it also has several anti-inflammatory effects that can reduce hyperinflammation. The exact mechanism of PRL's contribution to the severity of COVID-19 is unknown. The purpose of this review is to discuss the interaction between PRL and SARS-CoV2 infection and its possible association with the severity of COVID-19.

[PMID: 35147901 PMCID: PMC8831165 DOI: 10.1007/s11010-022-04381-9] [Citation(s) in RCA: 21] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Accepted: 01/27/2022] [Indexed: 12/15/2022]
Abstract
Prolactin (PRL) is a peptide hormone secreted from anterior pituitary involved in milk production in the females and regulation of sex drive in both sexes. PRL has pro-inflammatory and anti-inflammatory functions. High PRL serum level or hyperprolactinemia is associated with different viral infections. In coronavirus disease 2019 (Covid-19), which caused by positive-sense single-strand RNA virus known as severe acute respiratory distress syndrome coronavirus type 2 (SARS-CoV-2), PRL serum level is increased. PRL in Covid-19 may exacerbate the underlying inflammatory status by induction release of pro-inflammatory cytokines. However, PRL through its anti-inflammatory effects may reduce the hyperinflammatory status in Covid-19. The underlying mechanism of increasing PRL in Covid-19 is poorly understood. Therefore, in this review we try to find the potential anti-inflammatory or pro-inflammatory role of PRL in Covid-19. As well, this review was aimed to discuss the underlying causes and mechanisms for Covid-19-induced hyperprolactinemia.

DNA Methylation Pattern of CALCA and CALCB in Extremely Premature Infants with Monochorionic Triplets after Single-Embryo Transfer. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:1438837. [PMID: 34650662 PMCID: PMC8510797 DOI: 10.1155/2021/1438837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/29/2021] [Revised: 08/15/2021] [Accepted: 09/05/2021] [Indexed: 11/17/2022]
Abstract
Compared with full-term peers, premature infants are more likely to suffer from neonatal diseases and death. Variations in DNA methylation may affect these pathological processes. Calcitonin gene-related peptide (CGRP) plays a complex and diversified role in reproduction and chronic inflammation, and participates in the functional maintenance of vascular adaptation and trophoblast cells during pregnancy. Here, premature live births with single-chorionic triple embryos after single-embryo transfer were used as research objects, while full-term infants with double embryos and double-chorionic twins were used as controls. DNA was extracted from umbilical cord tissues for pyrosequencing to detect the methylation level of CpG island in CGRP promoter region. The average values of CGRP methylation in the umbilical cord tissues of very premature fetuses were higher than that of normal controls obtained from the databases. Immunofluorescence results showed that the expression of αCGRP was decreased in the blood vessel wall of the umbilical cord of monozygotic triplets, especially in death cases, while the βCGRP had a compensatory expression. In conclusion, our findings suggest that hypermethylation of CGRP might be considered as an important cause of serious neonatal morbidities.

Inhibition of TNFR1 Attenuates LPS Induced Apoptosis and Inflammation in Human Nucleus Pulposus Cells by Regulating the NF-KB and MAPK Signalling Pathway. Neurochem Res 2021; 46:1390-1399. [PMID: 33713325 DOI: 10.1007/s11064-021-03278-1] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 01/25/2021] [Accepted: 02/19/2021] [Indexed: 02/07/2023]
Abstract
Intervertebral disc degeneration (IDD) is accompanied by nucleus pulposus (NP) cell apoptosis, inflammation, and extracellular matrix degradation. Tumour necrosis factor receptor 1 (TNFR1) is a receptor of TNF-α, and is deeply involved in the processes of IDD. However, the effect of TNFR1 inhibition on IDD is not clear. Herein, we report that TNFR1 was increased in LPS-treated HNPCs. The aim of this study was to investigate the potential therapeutic effect of TNFR1 siRNA and selective antagonists of TNFR1 (GSK1995057) on HNPC damage. The results showed that the blockade of TNFR1 by TNFR1 siRNA and GSK1995057 effectively suppressed the cell viability loss, apoptosis, and inflammation induced by LPS in HNPCs. Furthermore, we found that TNFR1 siRNA and GSK1995057 inhibited activation of the NF-KB and MAPK signalling pathways in LPS-stimulated HNPCs. In summary, the blockade of TNFR1 effectively suppressed LPS-induced apoptosis and inflammation in HNPCs through the NF-KB and MAPK signalling pathways. This revealed that the blockade of TNFR1 may provide a potential therapeutic treatment for IDD.
