Abstract: The present disclosure relates to methods for eliciting an immune response to a cancer antigen in a subject in need thereof by introducing directly into at least one lymph node of the subject, and preferably at least two lymph nodes, a therapeutically effective amount of a cancer antigen and/or an adjuvant such that an immune response to the cancer antigen is activated or enhanced in the subject. The present disclosure also concerns pharmaceutical compositions that comprise a therapeutically effective amount of a cancer antigen and/or an adjuvant capable of mediating, and more preferably enhancing, activation of the immune system of a subject against cancer cells that are associated with any of a variety of cancers. The disclosure also relates to the use of such pharmaceutical compositions in the treatment or prevention of a cancer in a recipient subject.

Abstract: The present invention provides a device for assaying living cells comprising a substrate, wherein the substrate comprises one or more tethering molecules which adhere to the substrate and are capable of interacting with cell membranes of the cells, wherein the cells maintain a free-floating, non-adherent character when bound to the one or more tethering molecules.

Abstract: A method of inducing specific immune tolerance to myelin in an individual is provided. The method includes introducing directly into a lymph node of the individual an effective amount of a composition that contains a myelin antigen, a biodegradable material and at least one tolerogenic agent. The method is suitable for reducing the severity of symptoms of multiple sclerosis in individuals who suffer from primary-progressive multiple sclerosis (PPMS), and can halt or even reverse PPMS progression.
