Disclosed herein are switchable chimeric receptors, switchable chimeric receptor effector cells and chimeric receptor effector cell switches. The switchable chimeric receptor-ECs are generally T cells. The chimeric receptors have non-antibody extracellular domains that recognize a chimeric receptor binding partner on the chimeric receptor-EC switch or target cell. The chimeric receptor-ECs and switches may be used for the treatment of a disease or condition in a subject in need thereof.

The present invention relates to virus-like particles (VLPs) having a high affinity protein attachment system which allows interchangeable decoration with any functional molecule of choice. The present invention further relates to processes of producing the VLPs, including a rapid single cell process, and uses of the VLPs in research, diagnosis and as vaccines for use in prevention/treatment of diseases.
