Proteins of the TRIM family are involved in both innate immunity and the nervous system processes and may play an important role in the development of neurodegenerative diseases. In this work, we analyzed the expression of 35 genes of the TRIM family in neural progenitors (NPs), terminally differentiated neurons (TDNs) and glial derivatives (NGs) obtained from induced pluripotent stem cells (iPSCs) of healthy donors (HD) and patients with Parkinson’s disease (PD), in the absence of inflammatory stimuli and upon the induction of a nonspecific inflammatory response under the influence of TNFα. In NPs and TDNs of PD patients, compared with HD cells, differences in expression were observed for only a small number of TRIM genes. Under the influence of TNFα in TDNs, the expression of individual TRIM genes was activated, which was more significant in the cells of patients with PD compared to cells of HDs. In NGs of PD patients, the expression of many TRIM genes was initially reduced compared to HD cells and remained low or further decreased after exposure to TNFα. The data obtained demonstrate differences in the network of the TRIM family members in PD neurons and glia compared to control, and also show the multidirectional influence of the inflammatory stimulus on the expression of a number of TRIM genes in these types of cells. Considering the important role of many TRIM genes in the functioning of the innate immune system, it can be assumed that, in PD, more significant disturbances in the functioning of genes of this family occur in glia compared to neurons.
