Among the 24 subfamilies, harparctorinae is predominant and extensively investigated for biocontrol applications compared to the others subfamilies in Reduviidae. Being natural enemies of phytophagous insects, understanding the phylogeny of these predatory bugs can precise the selection of candidates to employ in insect pest management. In addition to morphological systematics, complete mitochondrial genome sequences provide great insights into the phylogeny for resolving evolutionary complexity. Complete mitochondrial genomes of four potential predatory harpactorinae and one outgroup triatominae were retrieved from NCBI GenBank database. Comparative analysis of the five mitogenomes and the nucleotide sequence between nad1 and nad2 genes were selected as the best option to distinguish. The nucleotide sequence between nad1- nad2 are found to be biased towards A and T similar to their respective complete mitog...

The T-lymphocyte antigen receptor recognises peptide antigen bound to so-called Major Histocompatibility Complex (MHC) molecules on the surface of the target cell. Activation of CD8-positive cytotoxic T-lymphocytes leads to lysis of the antigen presenting cell, whereas activation of CD4-positive T-helper lymphocytes results in release of regulatory and stimulatory cytokines. In this review, the results of recent years' research in the function of the cell mediated immune system is presented, followed by an overview of the role played by the mediated immune system in protection against infectious disease, cancer, or as a cause of immune-mediated pathology and autoimmunity.
