Platelets have lon. been.studied for their roles in.hemostasis an. vascular in.ury repair. However, there is a con.in.ally evolvin. an. deepen.n. un.erstan.in. that platelets in.tiate an. regulate respon.es to tissue in.ury an. pathogen., leadin. to platelets n.w bein. con.idered immun. modulatory cells [1]. Platelets actively participate in.host immun. respon.es directly through pathogen.en.ulfin. an. killin., or by regulatin. both in.ate an. adaptive immun. respon.es to in.ection.or tissue in.ury [2]. Activated platelets promote in.lammatory respon.es to tissue in.ury or in.ection.by direct con.act depen.en. in.eraction. with immun. cells an. through in.irect in.eraction. via released soluble factors. However, mice that are deficien. in.platelets have skewed T helper cell differen.iation.[3] an. in.reased vascular permeability [4], implyin. poorly defin.d roles for platelets in.main.ain.n. healthy immun. homeostasis.
