Device for enhancing immunostimulatory capabilities of T-cells
T-cells are generated with enhanced immunostimulatory capabilities for use in self therapy treatment protocols, by utilizing a biodegradable device with a biodegradable support that has one or more agents that are reactive to T-cell surface moieties. The biodegradable devices are mixed with the T-cells sufficiently so that the one or more agents cross-link with the T-cells' surface moieties and deliver a signal to the T-cells to enhance immunostimulatory capabilities.
1. A device for enhancing immunostimulatory capabilities of T-cells comprising:
an universal crosslinking agent comprising a support coated with a first material, wherein the first material is capable of crosslinking more than one array of second materials, the second materials capable of binding moieties on the surface of T-cells to deliver a signal to the T-cells and wherein each successive array of second materials is added at a later time in the T-cell response than the previous array of second materials.
2. The device of claim 1 wherein each of the one or more arrays comprises one or more second materials.
3. The device of claim 1 wherein each of the one or more arrays comprises two or more second materials.
4. The device of claim 1 wherein the universal crosslinking agent is capable of crosslinking second materials bound to the T-cell surface moieties.
5. The device of claim 1 wherein an array of second materials comprises one or more antibodies that have specificity to a T-cell surface moiety.
6. The device of claim 1 wherein the first material is an antibody.
7. The device of claim 1 wherein the support is a biodegradable support.
8. The device of claim 1 wherein the support is a biodegradable microsphere.
9. The device of claim 1 wherein the support is biodegradable into a substance that is nontoxic to humans.
10. The device of claim 1 wherein the support is a microsphere that degrades in 14 days or less.
11. The device of claim 1 wherein the second materials in an array are selected from anti-CD3, -CD28, -B7-H3, -PD-L1, -PD-L2, -IL-15R, -CD2, -CD48, -LFA-1, -CD43, -CD45, -CD4, -CD8, -CD7, -GM1, -LIGHT, -CD27, -OX40, -4-1BB, -CD30, -CD44, -CD31, -CD18/CD11a, -CD29, -CD54, -CD62L, -VLA4, -IL-2R, -IL-4R, IL-10R, -type II IFNR1 and R2, -type I IFNR, -IL-12beta1 and beta2, -IL-15R, -TNFR1, -TNFR2, and -IL-1R.
12. The device of claim 1 wherein the first material crosslinks at least two arrays of second materials, each array comprising at least two second materials and wherein the second array is added at a later time in the T-cell response than the first array.
13. The device of claim 1 wherein the first material crosslinks more than two arrays of second materials, each array comprising at least two second materials and wherein each successive array is added at a later time in the T-cell response than the previous array.
