Unfortunately\, traditional PK models are largely a bsent of the mechanisms driving drug interactions. Worse\, in some cases\, the classic PK modelling approach can lead to erroneous conclusions about the physiological system at hand. In this talk\, I will focus on the deve lopment of a physiological model of the production of neutrophils in the b one marrow. The model is a set of delay differential equations (DDEs) with state-dependent delays and a variable maturation rate\, constructed direc tly from the physiology of the hematopoietic system. \n\n \n\nThe process of producing a neutrophil is mediated by the endogenous cytokine granulocy te colony-stimulating factor (G-CSF)\, whose PKs are dictated by the negat ive feedback interactions between G-CSF and the neutrophil lineage. Here\, I will detail the determination of a novel PK model of G-CSF using the DD E physiological model as a basis\, and show how traditional PK approaches have previously mischaracterised the elimination kinetics of G-CSF. I will also touch on how\, due to its careful construction from the mechanisms o f the blood system\, the combined model can be applied to answer fundament al physiological questions\, and discuss future directions.\n DTSTART:20161124T211500Z DTEND:20161124T211500Z LOCATION:Room 920\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Morgan Craig - Harvard URL:/mathstat/channels/event/morgan-craig-harvard-2641 86 END:VEVENT END:VCALENDAR
