Provided herein are compositions and methods for treating neurological disorders. In particular, provided herein are neutrophils that rescue damaged neurons, methods of making such neutrophils, and methods of promoting generation of such neutrophils in vivo.

The present invention discloses novel methods, uses thereof, and compositions for modulating immune responses and homeostasis in a lymph node (LN). Moreover, structural and molecular characteristics of LN-innervating sensory neurons are provided. The present invention also discloses the target cells for LN-innervating sensory neurons in LN and molecular profiles of these target cells. These molecular characteristics provide therapeutic targets for modulating immune response and immune homeostasis in LN in an animal or a human.

A blood product (10), a method for preparing the blood product, a blood product obtainable by the method and a blood product preparing container means. The blood product comprises components from whole blood, especially fibrin, thrombocytes and leukocytes. The blood product (10) comprises a first layer (21), a second layer (22) and a third layer (23). The second layer (22) is adjacent to the first layer (21) and the third layer (23). The first layer (21) defines a first outer surface (24) of the blood product (10) and the third layer (23) defining a second outer surface (25) of the blood product (10). The first layer (21) comprises a majority of fibrin, the second layer (22) comprises a majority of thrombocytes and the third layer (23) comprises a majority of leukocytes.

In one aspect, a method of treating a subject having or at risk of having graft-versus-host disease (GvHD) generally includes administering to the subject a plurality of myeloid-derived suppressor cells (MDSCs) effective to ameliorate at least one symptom or clinical sign of graft-versus-host disease compared to a suitable control subject. In another aspect, a method of treating a tumor in a subject generally includes administering to the subject an anti-tumor therapy and co-administering to the subject an inflammasome inciting agent in an amount effective to increase inflammasome activation of MDSCs sufficiently to reduce suppressor function of the MDSCs.

Provided are compositions and methods for treating a subject having a primary immune deficiency (PID), for example who is suffering from a chronic viral, bacterial, or fungal infection, using autologous granulocytes, autologous lymphocytes, and/or NK cells containing exogenous mRNA encoding the missing or defective protein.

The invention provides a method for separating a mammal early follicle to obtain a single oocyte and a single granulocyte thereof. The method is capable of separating a mammal early follicle to obtain an active single oocyte and a corresponding granulocyte thereof. The invention further provides a kit for obtaining a single oocyte and a single granulocyte thereof from a mammal early follicle.

The present invention provides methods of producing in vitro derived neutrophils or macrophages in xenogen- and serum-free conditions from pluripotent stem cells and in vitro derived populations of neutrophils and macrophages. Methods of treatment using in vitro derived neutrophils or macrophages are also contemplated.
