Maintenance of health and physiological homeostasis is a synergistic process involving tight regulation of proteins, transcription factors and other molecular processes. The immune system consists of innate and adaptive immune cells that are required to sustain immunity. The presence of pathogens and tumour cells activates innate immune cells, in particular Natural Killer (NK) cells. Stochastic expression of NK receptors activates either inhibitory or activating signals and results in cytokine production and activation of pathways that result in apoptosis of target cells. Thus, NK cells are a necessary component of the immunological process and aberrations in their functional processes, including equivocal …

Quantitative (real-time) PCR (qPCR) represents a highly sensitive, sequence-specific, and reproducible technique for the gel-free detection and quantitation of nucleic acids. Owing to its large dynamic range and throughput, this approach has become the chosen method for rapid quantification of mRNA levels in biological samples. The sensitivity of this method permits the reliable detection of low concentrations of initial template, while delivering a linear range of up to 10 orders of magnitude in copy number. This chapter details the basic methodology behind key components of a qPCR experiment, including sample preparation, fluorescent chemistries, primer/probe design, and data analysis applicable to …
