Autologous NK cells propagated and activated decrease senescence markers in human PBMCs.

Aging is a multifactorial process involving many steps including senescence. The immune system plays a critical role in aging where chronic inflammation and senescence has been shown to be detrimental. Natural killer (NK) cells are the predominant innate lymphocyte subset that mediate various responses to include surveillance and elimination of senescent cells.

Profiling the humoral immune response to infection by using proteome microarrays: high-throughput vaccine and diagnostic antigen discovery.

Despite the increasing availability of genome sequences from many human pathogens, the production of complete proteomes remains at a bottleneck. To address this need, a high-throughput PCR recombination cloning and expression platform has been developed that allows hundreds of genes to be batch-processed by using ordinary laboratory procedures without robotics. The method relies on high-throughput amplification of each predicted ORF by using gene specific primers, followed by in vivo homologous recombination into a T7 expression vector.
