Investigation of Linc-MAF-4 expression as an effective marker in brucellosis.

Brucellosis is a zoonotic disease that is one of the most common infectious diseases. Cellular immunity is the main immune response against brucella. Long non coding RNAs are a new subset of genes that could regulate cell function and may gene regulation. We aim to investigate whether the level of Linc-MAF-4 and cMAF have considerable differences in brucella infection.

In this experiment 99 patients with brucellosis were divided into three groups of acute, undertreatment and relapse and 30 volunteers with negative serologic tests as control group. The expression levels were detected using quantitative polymerase chain reaction (qPCR). Statistical analysis was performed using SPSS software version 25.0. Results showed that the expression of Linc-MAF-4 was significantly increased in the acute group in comparison to control and relapse groups.

Also, cMAF expression was significantly increased in the relapse group versus the control group. Our study showed these genes play important roles in the immune response include regulating naïve T cell differentiation to T helper cells in Brucella infection. We propose that Linc-MAF-4 could be a potential biomarker for the screening, diagnosis and treatment of brucellosis.
