This chapter reviews the roles of cytokines and glial cells in chronic pain and in psychiatric disorders, especially depression. One important role of cytokines is in communicating between activated glia and neurons, at all levels of the nervous system. This process of neuroinflammation plays important roles in pain and depression. Cytokines may also directly regulate neuronal excitability. Many cytokines have been implicated in both pain and psychiatric disorders, including interleukin-1β‎ (IL-1β‎), tumor necrosis factor-α‎, and IL-6. More generally, an imbalance between type 1, pro-inflammatory cytokines and type 2, anti-inflammatory cytokines has been implicated in both pain and psychiatric disorders. Activation of the sympathetic nervous system can contribute to both pain and psychiatric disorders, in part through its actions on inflammation and the cytokine profile.

Intracardiac Nervous System

One of the major roles of the intracardiac nervous system (ICNS) is to act as the final site of signal integration for efferent information destined for the myocardium to enable local control of heart rate and rhythm. Multiple subtypes of neurons exist in the ICNS where they are organized into clusters termed ganglionated plexi (GP). The majority of cells in the ICNS are actually glial cells; however, despite this, ICNS glial cells have received little attention to date. In the central nervous system, where glial cell function has been widely studied, glia are no longer viewed simply as supportive cells but rather have been shown to play an active role in modulating neuronal excitability and synaptic plasticity. Pioneering studies have demonstrated that in addition to glia within the brain stem, glial cells within multiple autonomic ganglia in the peripheral nervous system, including the ICNS, can also act to modulate cardiovascular function. Clinically, patients with atrial fibrillation (AF) undergoing catheter ablation show high plasma levels of S100B, a protein produced by cardiac glial cells, correlated with decreased AF recurrence. Interestingly, S100B also alters GP neuron excitability and neurite outgrowth in the ICNS. These studies highlight the importance of understanding how glial cells can affect the heart by modulating GP neuron activity or synaptic inputs. Here, we review studies investigating glia both in the central and peripheral nervous systems to discuss the potential role of glia in controlling cardiac function in health and disease, paying particular attention to the glial cells of the ICNS.

Chronic pain is known to be caused by sensitization within the pain circuits. An imbalance occurs between excitatory and inhibitory transmission that enables this sensitization to form. In addition to neurons, the contribution of central glia, especially astrocytes and microglia, to the pathogenesis of pain induction and maintenance has been identified. This has led to the targeting of astrogliosis and microgliosis to restore the normal functions of astrocytes and microglia to help reverse chronic pain. Gliosis is broadly defined as a reactive response of glial cells in response to insults to the central nervous system (CNS). The role of glia in the peripheral nervous system (PNS) has been less investigated. Accumulating evidence, however, points to the contribution of satellite glial cells (SGCs) to chronic pain. Hence, understanding the potential role of these cells and their interaction with sensory neurons has become important for identifying the mechanisms underlying pain signaling. This would, in turn, provide future therapeutic options to target pain. Here, a viewpoint will be presented regarding potential future directions in pain research, with a focus on SGCs to trigger further research. Promising avenues and new directions include the potential use of cell lines, cell live imaging, computational analysis, 3D tissue prints and new markers, investigation of glia–glia and macrophage–glia interactions, the time course of glial activation under acute and chronic pathological pain compared with spontaneous pain, pharmacological and non-pharmacological responses of glia, and potential restoration of normal function of glia considering sex-related differences.

In recent years there has been an increase in the frequency of multiple pregnancies and the associated perinatal losses. It is a result of multiple pregnancy in ART refers to a high-risk gestation, at which premature births occur in 2 times more often than in singleton pregnancies. The objective: to determine the role of pro-inflammatory cytokines in the pathogenesis of premature labor in multiple pregnancy, as a result of assisted reproductive technology. Patients and methods. to determine the pro-inflammatory cytokines that all pregnant with bagtopliddyam held immunosorbent assay, defined concentrations of interleukin (IL) in serum and cervical mucus. Results. The analysis of the levels of pro-inflammatory cytokines (IL-1, IL-8) in the test environment, found high concentrations in the surveyed women with multiple pregnancy, due to the use of ART, compared with spontaneous multiple and singleton pregnancy. Increased concentration of proinflammatory cytokines in patients with multiple pregnancy by ART is associated with their synthesis at the system level, it stimulated foci of inflammation in the female genitals and extragenital localization. This correlates with the clinical data and statistical analysis, patients with multiple pregnancy as a result of ART had weighed infectious-inflammatory history. Conclusion. The study showed that elevated levels of proinflammatory cytokines in the systemic and local level in patients with multiple pregnancy due to ART, typical for women with miscarriage, because of the physiological course of pregnancy characterized by the predominance of anti-inflammatory cytokines that prevent rejection of the fetus as a foreign factor. Based on the data obtained proved the role of systemic inflammatory factors in the genesis of preterm labor in women with a multiple pregnancy, as a result of assisted reproductive technology. Key words: multiple pregnancy, assisted reproductive technology, premature birth, interleukine-1, interleukine-8.
