The present disclosure provides populations of cells comprising partially mature and optimally activated dendritic cells that can be used for administration to individuals having a cancer and/or tumor. Partially matured dendritic cells, those contacted with a dendritic cell maturation agent for about 10 to about 19 hours, upon administration efficiently take up and process tumor antigens in the area of the tumor site, complete maturation, and can subsequently migrate to the lymph nodes of a treated individual. Once in a lymph node the now fully mature antigen presenting dendritic cells secrete the appropriate cytokines (e.g., TNFα, IL-6, IL-8, and/or IL-12) and contact T cells inducing a substantial and optimal clinical and/or anti-tumor immune response.

A methodology to obtain large numbers of allospecific human Tr1 lymphocytes in vitro differentiated with phenotype and suppressive function stability in presence of proinflammatory cytokines, by using donor tolerogenic dendritic cells (DC10) derived from donor monocytes and from a not related receptor (allogeneic) naîve T cells cocultures. The obtained cells with the present methodology are characterized by the expression of a Tr1 regulatory phenotype (CD4+, CD49b+, LAG-3+), being high IL-10 producers, and also they express additional co-inhibitory molecules as PD1, TIM-3, CD39, CTLA-4 y TIGIT. Moreover, the cellular product obtained by this methodology is able to maintain a stable phenotype and suppressive function in presence of proinflammatory cytokines (IL-1β, IL-6, IFN-γ y TNF-α). The numbers, purity, and stability of the Tr1 obtained by this methodology, make them great candidates for their use as therapeutic tools in transplantation.

The present disclosure provides methods of treating neurodegenerative diseases, including administering agents that block dendritic cells from entering the brain from the blood. The present further describes methods for detecting the selective migration of dendritic cells from blood into brain as a marker of human neurodegenerative disease. The present disclosure further describes methods that can be used to evaluate and compare different embodiments of methods detecting migration of dendritic cells using transgenic mice that overexpress various mutations associated with induction of distinct neurodegenerative disease pathologies. These present disclosures are particularly useful in the design and evaluation of clinical trials for neurodegenerative diseases, such as Alzheimer's disease, small vessel diseases that include cerebral amyloid angiopathy, and fronto-temporal dementias, and specifically for the design and evaluation of clinical trials of agents that block dendritic cells from entering the brain for therapeutic purpose.

Methods are provided for treating blood monocytes to produce functional antigen presenting dendritic cells. An extracorporeal quantity of a subject's blood is treated to separate the blood and produce a leukocyte concentrate comprising monocytes and plasma containing proteins. The leukocyte concentrate comprising monocytes and plasma containing proteins is pumped through a plastic treatment device, such as a photopheresis device. The resulting treated cells may be incubated for a sufficient period of time to allow the monocytes to form dendritic cells, or the treated cells may be reinfused directly to the subject.
