Campe KNJ, Redlich A, Zenclussen AC, Busse M. An increased proportion of progesterone receptor A in peripheral B cells from women who ultimately underwent spontaneous preterm birth. J Reprod Immunol 2022; 154:103756. [PMID: 36356365 DOI: 10.1016/j.jri.2022.103756] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Revised: 09/08/2022] [Accepted: 10/17/2022] [Indexed: 11/05/2022]
Abstract
The enormous challenge in unraveling the etiology of preterm birth (PTB) is to understand the complex interactions between gestational hormones, the immune system and reproductive tissues. PTB can be divided into spontaneous PTB (sPTB) and medically-indicated PTB, e.g. due to preeclampsia (PE) or HELLP syndrome. Progesterone (P4), important for establishment and maintenance of pregnancy, exerts anti-inflammatory effects. The impact of P4 on B cells and its support of maintaining maternal-fetal tolerance is widely unexplored. Therefore, we aimed to determine whether B cells express the progesterone receptor (PR) and to dissect a possible role of PR+ B cells in PTB. We found enhanced IL-6, IL-21 and TNF-α concentrations in maternal plasma in patients with sPTB and PE/HELLP compared to term delivery (TD), accompanied by enhanced PR-A expression by CD19+ B cells. In a second phase of the study, we recruited patients with imminent PTB (iPTB) and controls. Samples were collected at hospital admission and to a later time point, then divided into iPTB patients who delivered preterm and patients whose PTB was prevented. Within the group of iPTB patients, we observed very clear differences: enhanced levels of pro-inflammatory cytokines and increased percentages of PR-A+CD19+ B cells were found in iPTB patients that delivered preterm compared to patients who did not deliver preterm. We conclude that PTB is associated with the activation of an inflammatory pathway leading to the induction of PR-A by B cells. This might further trigger inflammation, result in the break of maternal-fetal tolerance and induce delivery.

Advantages and drawbacks of dexamethasone in glioblastoma multiforme. Crit Rev Oncol Hematol 2022; 172:103625. [PMID: 35158070 DOI: 10.1016/j.critrevonc.2022.103625] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Revised: 02/01/2022] [Accepted: 02/07/2022] [Indexed: 12/25/2022] Open
Abstract
The most widespread, malignant, and deadliest type of glial tumor is glioblastoma multiforme (GBM). Despite radiation, chemotherapy, and radical surgery, the median survival of afflicted individuals is about 12 months. Unfortunately, existing therapeutic interventions are abysmal. Dexamethasone (Dex), a synthetic glucocorticoid, has been used for many years to treat brain edema and inflammation caused by GBM. Several investigations have recently shown that Dex also exerts antitumoral effects against GBM. On the other hand, more recent disputed findings have questioned the long-held dogma of Dex treatment for GBM. Unfortunately, steroids are associated with various undesirable side effects, including severe immunosuppression and metabolic changes like hyperglycemia, which may impair the survival of GBM patients. Current ideas and concerns about Dex's effects on GBM cerebral edema, cell proliferation, migration, and its clinical outcomes were investigated in this study.

Abstract
BACKGROUND The highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) has been responsible for several viral attacks in the Asian porcine industry, since the first outbreak in China in 2006. During the early stages of the HP-PRRSV infection, high levels of proinflammatory cytokines are noted in the host peripheral blood, which are accompanied by severe lesions in the lungs and immune system organs; these are considered as the greatest contributors to the overall disease burden. We hypothesized that the anti-PRRSV response in piglets might be mediated by the hypothalamus-pituitary-adrenal (HPA) axis, which led to a decrease in the psycho-neuroendocrinological manifestation of HP-PRRSV etiology via immune response regulation. RESULTS We investigated the regulation of the HPA axis in HP-PRRSV-infected piglets that were treated with 1 mg/kg body weight (b. w.)/day mifepristone (RU486) or 2 mg/kg b.w./day dexamethasone (DEX). Both RU486 and DEX enhanced the disease status of the piglets infected by the HP-PRRSV HuN4 strain, resulting in high mortality and more severe pathological changes in the lungs. CONCLUSIONS HP-PRRSV infection activates the HPA axis, and artificial regulation of the immune-endocrine system enhances disease severity in HP-PRRSV-infected piglets. Thus, DEX and RU486 should be avoided in the clinical treatment of HP-PRRS.

Significance of glucocorticoid receptor expression in patients with non-small cell lung cancer treated with pemetrexed-based chemotherapy. Cancer Chemother Pharmacol 2017; 80:851-860. [PMID: 28755014 DOI: 10.1007/s00280-017-3399-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2017] [Accepted: 07/18/2017] [Indexed: 01/19/2023]
Abstract
BACKGROUND Pemetrexed is the preferred chemotherapy agent in the management of non-squamous non-small cell lung cancer (non-sq-NSCLC), but lacks biomarkers predicting its efficacy. Dexamethasone, one of the premedications of pemetrexed, may downregulate p53 through the glucocorticoid receptor (GR). The purpose of our study was to explore the effect of GR in peripheral blood mononuclear cells (PBMC) and its role in predicting pemetrexed efficacy. METHODS In all, 122 patients with stage IV non-sq-NSCLC who received first-line pemetrexed-containing chemotherapy were retrospectively reviewed. The expression of GR in PBMC was measured before treatment with pemetrexed using real-time PCR was used to detect the levels of GRα and GRβ. RESULTS The response rate for all patients was 38.5%, with a median progression-free survival (PFS) of 5.9 months and overall survival (OS) of 14.3 months. In univariate analyses, patients with a low GRα/GRβ ratio in PBMC had higher RR, better PFS, and better OS than those with a high GRα/GRβ ratio (RR: 48.2 vs. 30.3%, p = 0.043; mPFS: 6.9 vs. 4.0 months, p < 0.001; mOS: 18.7 vs. 12.2 months, p = 0.005). The baseline GRα/GRβ ratio was an independent factor for RR (odds ratio [OR] = 0.451, 95% CI 0.208-0.978; p = 0.044), PFS (HR = 1.584, 95% CI 1.094-2.295; p = 0.015), and OS (HR = 1.761, 95% CI 1.195-2.595; p = 0.004). CONCLUSIONS Baseline GRα/GRβ ratio in PBMC may play a role in predicting the efficacy of first-line pemetrexed-containing chemotherapy in stage IV non-sq NSCLC patients.

Abstract
The maternal-fetal interface is an immunologically unique site that allows the tolerance to the allogenic fetus and maintains host defense against possible pathogens. Balanced immune responses are required for the maintenance of successful pregnancy. It has been demonstrated that innate immune disturbances may be responsible for some adverse pregnancy outcomes such as preeclampsia (PE); hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome; intrauterine growth restriction (IUGR); and recurrent spontaneous abortion (RSA). Observational studies suggest that immunomodulatory treatments in pregnancy-specific complications may improve both the hematological/biochemical features in the mother and the perinatal outcomes. The following review will discuss how recent and relevant findings in the field of the innate immunity have advanced our understanding of the role of inflammation and innate immune system in the pathogenesis of pregnancy failure and will discuss the therapeutic outcomes of the existing studies and clinical trials in light of these new insights.
