RESEARCH AND EDUCATION IN BIOMEDICINE FROM GENES TO HUMAN

D. Fridmanis lab

Due to expertize in various techniques of molecular biology and past research experience, the scientific interests of the group are diverse. However two major directions – microbiome studies and functional studies of G-protein coupled receptors (GPCR) prevail over others. In the field of microbiome we are actively studying such human body sites as gut, heart valve, blood, throat, stomach and hair follicle while GPCR research is directed towards search of novel peptide ligands for orphan receptors, molecular studies of melanocortin receptors and functional characterization of melanocortin receptors that are encoded by minor alleles of various animal species. In addition within the scope of collaboration based research we are participating in soil, environmental, wastewater, micro plastics, insect gut, plant and seed microbiome studies as well as performing genetic characterization of local ruminant breeds and urban Northern goshawks (Accipiter gentilis).
