Kocer Lab. on Emerging Viral Diseases
RESEARCH INTERESTS
Our research includes the detection of genetic variations in influenza viruses, understanding the functions of these variations, and risk assessment. With the inclusion of next-generation sequencing technology in scientific studies, it has become easier to detect minor variants as well as major variants in the virus genome. In fact, in some studies, it has been shown that minor variants in the virus population have an important role in antigenic changes that allow the virus to escape from the immune system and mutations that increase virus permeability (Poon et al., 2016; Dinis et al., 2016). Therefore, close follow-up of these genetic changes is very important in selecting the most accurate influenza strains in vaccine production and in developing more effective antivirals. Our main objectives are to detect genetic variations in the genomes of human influenza viruses by next-generation sequencing, to perform in silico structural analysis based on the locations of the variations in the genome, and to look at the phylogenetic origins of the gene segments. Although rare, gene reassortment can be seen between seasonal influenza viruses. For this reason, with the help of phylogenetic analysis, investigating the frequency of such reassortment events that may occur during co-infection with different subtypes and determining the origins of viral genes are among our research topics, as well. In summary, our main goal is to examine influenza A viruses with the help of various molecular and bioinformatic analysis, focusing on the detection of new variants and the determination of the functions of these variations. Such studies form the basis for the development of diagnostic kits against current strains and the production of effective antivirals and vaccines.
