Abstract
Interleukin-8 (IL-8/CXCL8), an essential CXC chemokine, significantly influences psychoneuroimmunological processes and affects neurological and psychiatric health. It exerts a profound effect on immune cell activation and brain function, suggesting potential roles in both neuroprotection and neuroinflammation. IL-8 production is stimulated by several factors, including reactive oxygen species (ROS) known to promote inflammation and disease progression. Additionally, CXCL8 gene polymorphisms can alter IL-8 production, leading to potential differences in disease susceptibility, progression, and severity across populations. IL-8 levels vary among neuropsychiatric conditions, demonstrating sensitivity to psychosocial stressors and disease severity. IL-8 can be detected in blood circulation, cerebrospinal fluid (CSF), and urine, making it a promising candidate for a broad-spectrum biomarker. This review highlights the need for further research on the diverse effects of IL-8 and the associated implications for personalized medicine. A thorough understanding of its complex role could lead to the development of more effective and personalized treatment strategies for neuropsychiatric conditions.

The effects of a single aerobic exercise session on mood and neural emotional reactivity in depressed and healthy young adults: A late positive potential study. Psychophysiology 2022; 60:e14137. [PMID: 35790005 PMCID: PMC10078493 DOI: 10.1111/psyp.14137] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Revised: 06/09/2022] [Accepted: 06/15/2022] [Indexed: 12/01/2022]
Abstract
Depression has been characterized by lowered mood and unfavorable changes in neural emotional reactivity (altered brain responses to emotional stimuli). Physical exercise is a well-established strategy to improve the mood of healthy and depressed individuals. Increasing evidence suggests that exercise might also improve emotional reactivity in healthy adults by increasing or decreasing brain responses to positive or negative stimuli, respectively. It is unknown, however, if exercise could also benefit emotional reactivity in depressed individuals. We investigated the effects of a single aerobic exercise session on mood and emotional reactivity in 24 depressed and 24 matched healthy young adults. Self-reported mood and neural reactivity to emotional pictures (indexed by the EEG late positive potential, LPP) were assessed before and after two experimental protocols: exercise (36 min of moderate-intensity exercise at 75% of maximal heart rate) and seated rest condition (36 min). In the healthy control group, exercise improved self-reported mood and neural emotional reactivity (increasing LPP to positive pictures). In the depressed group, exercise improved self-reported mood; however, it did not affect neural emotional reactivity. Additional analyses performed on both groups revealed that exercise-induced changes in emotional reactivity are associated with the severity of depressive symptoms: the effectiveness of exercise in improving emotional reactivity decreases with the severity of depressive symptoms. Overall, the study further strengthens the claim of a beneficial role of exercise on mood and emotional reactivity. It also suggests that a single aerobic exercise session might have a limited influence on neural emotional reactivity in depressed individuals.

Abstract
Multiple sclerosis (MS) is a demyelinating disease characterized by plaque formation and neuroinflammation. The plaques can present in various locations, causing a variety of clinical symptoms in patients with MS. Coronavirus disease-2019 (COVID-19) is also associated with systemic inflammation and a cytokine storm which can cause plaque formation in several areas of the brain. These concurring events could exacerbate the disease burden of MS. We review the neuro-invasive properties of SARS-CoV-2 and the possible pathways for the entry of the virus into the central nervous system (CNS). Complications due to this viral infection are similar to those occurring in patients with MS. Conditions related to MS which make patients more susceptible to viral infection include inflammatory status, blood-brain barrier (BBB) permeability, function of CNS cells, and plaque formation. There are also psychoneurological and mood disorders associated with both MS and COVID-19 infections. Finally, we discuss the effects of exercise on peripheral and central inflammation, BBB integrity, glia and neural cells, and remyelination. We conclude that moderate exercise training prior or after infection with SARS-CoV-2 can produce health benefits in patients with MS patients, including reduced mortality and improved physical and mental health of patients with MS.

Zar A, Ahmadi E, Amani D, Ramsbottom R. Acute effect of two exercise intensity programs on interleukin-6, interleukin-1 beta and tumour necrosis factor-α in female futsalists. COMPARATIVE EXERCISE PHYSIOLOGY 2022.

Abstract
Duration, intensity, and type of exercise can affect serum cytokine levels and change inflammatory indices. The present study aimed to examine the acute effect of two different exercise intensity programs on levels of circulating interleukin (IL)-6, IL-1β and tumour necrosis factor-α (TNF-α) in athletes. Eleven female futsal players aged 20.6±1.2 years completed this cross-over study. Participants performed, either a MI (moderate intensity: 60-65%) or a HI (high intensity: 75-80% heart rate reserve) exercise program. The study was performed on different days separated by a 1-week washout period. Each session consisted of 30 min running, either MI or HI. Blood samples were taken before (Pre) and immediately after (Post) each exercise session from an antecubital vein by venous puncture in a seated position. A Student’s t-test (P<0.05) was used to examine any difference between Pre and Post values. The results showed that IL-6 (P=0.22), IL-1β (P=0.90) and TNF-α (P=0.63) serum concentrations were not significantly different after moderate-intensity exercise. Similarly, high-intensity exercise did not significantly change serum concentrations of TNF-α (P=0.63), and IL-1β (P=0.18). However, HI caused a significant increase in IL-6 (P=0.04). A significant correlation was observed only between IL-1β and IL-6 (r=-0.761, P=0.01) after MI exercise. Based on the findings of the present study, the intensity of exercise can affect some cytokines, such as IL-6 in female futsal players.
