Objective: Interleukin 34 (IL-34) is a molecule whose expression is increased in conditions such as autoimmune disorders, inflammation, and infections. Our study aims to determine the role of IL-34 in the diagnosis, follow-up, and prognosis of Coronavirus Disease-19 (COVID-19).
Method: A total of 80 cases were included in the study as 40 COVID-19 positive patient groups and 40 COVID-19 negative control groups. The COVID-19-positive group consisted of 20 intensive-care unit (ICU) patients and 20 outpatients. Serum IL-34, c-reactive protein (CRP), ferritin, D-dimer, troponin I, hemogram, and biochemical parameters of the cases were studied and compared between groups.
Results: IL-34 levels were significantly higher in the COVID-19-positive group than in the negative group. IL-34 levels increased in correlation with CRP in predicting the diagnosis of COVID-19. IL-34 levels higher than 31.75 pg/m predicted a diagnosis of COVID-19. IL-34 levels did not differ between the outpatient and ICU groups in COVID-19-positive patients. IL-34 levels were also not different between those with and without lung involvement.
Conclusion: While IL-34 levels increased in COVID-19-positive patients and were successful in predicting the diagnosis of COVID-19, it was not found to be significant in determining lung involvement, risk of intensive care hospitalization, and prognosis. The role of IL-34 in COVID-19 deserves further evaluation.

Background: Certain peripheral proteins are believed to be involved in the development of Alzheimer's disease (AD), but the roles of other new protein biomarkers are still unclear. Current treatments aim to manage symptoms, but they are not effective in stopping the progression of the disease. New drug targets are needed to prevent Alzheimer's disease.

Objectives: Obsessive-compulsive disorder (OCD) is a prevalent mental health condition that impacts daily life. It is thought to be associated with genetic, biological, and structural brain changes, serotonergic abnormalities, altered neuromodulation, and environmental factors. Limited observational studies have examined cytokines in Bangladeshi patients with OCD.

The potential role of interleukin-34 (IL-34), an important cytokine that regulates intestinal function in mammals, is currently being explored in the context of fish intestinal diseases. In this study, we assessed the preventive potential of recombinant Megalobrama amblycephala IL-34 (rMaIL-34) protein in bacterial enteritis. MaIL-34 exhibited conserved structural and evolutionary features with teleost IL-34 and was found to be involved in the intestinal immune response to Aeromonas hydrophila infection.

Article Synopsis
- The study investigates the colony-stimulating factor-1 receptor (MCSFR) in rainbow trout, identifying four gene variants, including two previously unrecognized, and explores their expression levels in various tissues.
- The protein structure of MCSFRs includes five immunoglobulin-like domains and suggests a conserved function across species.
- Following infection with Yersinia ruckeri, different MCSFR paralogues exhibit unique expression patterns, showing complex regulatory mechanisms influenced by various stimuli, enhancing the understanding of immune responses in fish.
