Abakumova TV, Antoneeva II, Gening TP. Killer Function of Circulating Neutrophils in Relation to Cytokines in Uterine Myoma and Endometrial Cancer. Bull Exp Biol Med 2024; 176:607-611.

Abstract
The study presents the killer functions of circulating neutrophils: myeloperoxidase activity, the ability to generate ROS, phagocytic activity, receptor status, NETosis, as well as the level of cytokines IL-2, IL-4, IL-6, IL-17A, and IL-18, granulocyte CSF, monocyte chemotactic protein 1, and neutrophil elastase in the serum of patients with uterine myoma and endometrial cancer (FIGO stages I-III). The phagocytic ability of neutrophils in uterine myoma was influenced by serum levels of granulocyte CSF and IL-2 in 54% of the total variance. The degranulation ability of neutrophils in endometrial cancer was determined by circulating IL-18 in 50% of the total variance. In uterine myoma, 66% of the total variance in neutrophil myeloperoxidase activity was explained by a model dependent on blood levels of IL-17A, IL-6, and IL-4. The risk of endometrial cancer increases when elevated levels of monocyte chemotactic protein 1 in circulating neutrophils are associated with reduced ability to capture particles via extracellular traps (96% probability).

Non-Transcriptional and Translational Function of Canonical NF- κB Signaling in Activating ERK1/2 in IL-1 β-Induced COX-2 Expression in Synovial Fibroblasts. Front Immunol 2020; 11:579266. [PMID: 33117381 PMCID: PMC7576893 DOI: 10.3389/fimmu.2020.579266] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Accepted: 09/22/2020] [Indexed: 12/30/2022] Open
Abstract
The pro-inflammatory cytokine interleukin 1β (IL-1β) induces the synthesis of prostaglandin E2 by upregulating cyclooxygenase-2 (COX-2) in the synovial tissue of individuals with autoimmune diseases, such as rheumatoid arthritis (RA). IL-1β-mediated stimulation of NF-κB and MAPK signaling is important for the pathogenesis of RA; however, crosstalk(s) between NF-κB and MAPK signaling remains to be understood. In this study, we established a model for IL-1β-induced synovitis and investigated the role of NF-κB and MAPK signaling in synovitis. We observed an increase in the mRNA and protein levels of COX-2 and prostaglandin E2 release in cells treated with IL-1β. NF-κB and ERK1/2 inhibitors significantly reduced IL-1β-induced COX-2 expression. IL-1β induced the phosphorylation of canonical NF-κB complex (p65 and p105) and degradation of IκBα. IL-1β also induced ERK1/2 phosphorylation but did not affect the phosphorylation levels of p38 MAPK and JNK. IL-1β failed to induce COX-2 expression in cells transfected with siRNA for p65, p105, ERK1, or ERK2. Notably, NF-κB inhibitors reduced IL-1β-induced ERK1/2 phosphorylation; however, the ERK1/2 inhibitor had no effect on the phosphorylation of the canonical NF-κB complex. Although transcription and translation inhibitors had no effect on IL-1β-induced ERK1/2 phosphorylation, the silencing of canonical NF-κB complex in siRNA-transfected fibroblasts prevented IL-1β-induced phosphorylation of ERK1/2. Taken together, our data indicate the importance of the non-transcriptional/translational activity of canonical NF-κB in the activation of ERK1/2 signaling involved in the IL-1β-induced development of autoimmune diseases affecting the synovial tissue, such as RA.

Abstract
Phagocytosis is a cellular process for ingesting and eliminating particles larger than 0.5 μm in diameter, including microorganisms, foreign substances, and apoptotic cells. Phagocytosis is found in many types of cells and it is, in consequence an essential process for tissue homeostasis. However, only specialized cells termed professional phagocytes accomplish phagocytosis with high efficiency. Macrophages, neutrophils, monocytes, dendritic cells, and osteoclasts are among these dedicated cells. These professional phagocytes express several phagocytic receptors that activate signaling pathways resulting in phagocytosis. The process of phagocytosis involves several phases: i) detection of the particle to be ingested, ii) activation of the internalization process, iii) formation of a specialized vacuole called phagosome, and iv) maturation of the phagosome to transform it into a phagolysosome. In this review, we present a general view of our current understanding on cells, phagocytic receptors and phases involved in phagocytosis.

Abstract
IgG is the major immunoglobulin class produced during an immune response against foreign antigens and efficiently provides protection through its bifunctional nature. While the Fab domains confer highly specific recognition of the antigen, the Fc domain mediates a wide range of effector functions that modulate several aspects of innate and adaptive immunity. Engagement of the various types of Fcγ receptors (FcγRs) by an IgG Fc domain can activate distinct immunomodulatory pathways with pleiotropic functional consequences for several leukocyte types. Fc effector functions are not limited to phagocytosis and cytotoxicity of IgG-opsonized targets but exhibit remarkable diversity and include modulation of leukocyte activity and survival, cytokine and chemokine expression, maturation of antigen-presenting cells, antigen processing and presentation, B-cell selection and IgG affinity maturation, as well as regulation of IgG production. These functions are initiated upon specific interactions of the Fc domain with the various types of FcγRs-a process that is largely determined by the structural heterogeneity of the IgG Fc domain. Modulation of the Fc-associated glycan structure and composition along with differences in the primary amino acid sequence among the IgG subclasses represent the two main diversification mechanisms of the Fc domain that generate a spectrum of Fc domain phenotypes with distinct affinity for the various FcγR types and differential capacity to activate immunomodulatory pathways.
