METHOD FOR LARGE-SCALE PRODUCTION OF ALLOSPECIFIC TYPE 1 REGULATORY TREGS (TR1) STABLE IN THE PRESENCE OF PROINFLAMMATORY CYTOKINES WITH THERAPEUTIC POTENTIAL IN TRANSPLANTATION

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.

EXPANSION OF GAMMA DELTA T CELLS, COMPOSITIONS, AND METHODS OF USE THEREOF

The present invention provides methods of expanding γδ T cells from a non-haematopoietic tissue source. Further provided are compositions of expanded γδ T cells and methods of using the expanded γδ T cells (e.g., a part of an adoptive T cell therapy).

RECOMBINANT ADENO-ASSOCIATED VIRUS VECTORS WITH CD14 PROMOTER AND USE THEREOF
20220119842 · 2022-04-21 ·

The present disclosure provides rAAV vectors and rAAV virions that specifically express exogenous nucleic acid sequences in CD14.sup.+ cells. The rAAV vectors or virions are useful for specifically expressing exogenous nucleic acid sequences encoding, for example, cancer antigens, viral antigens, and/or bacterial antigens in monocytes and dendritic cells. The rAAV transduced CD14.sup.+ cells can be used as antigen presenting cells that induce antigen-specific T cell responses. The present disclosure further provides methods producing rAAV virions and methods of immunotherapy.

EX VIVO GENERATION OF GAMMA DELTA FOXP3+ REGULATORY T CELLS AND THERAPEUTIC USES THEREOF

The present invention relates to a method for ex vivo generating and expanding γδ Foxp3.sup.+ regulatory T cells, and therapeutic uses thereof. The inventors performed the induction of Foxp3+ expression in ex vivo human induced tumor-antigen specific CD4− TCRγδ unrestricted T cells and the induction of autologous CD8-mediated T-cell responses against tumor-antigen specific FOXP3 expressing CD4+ TCRγδ unrestricted T cells. The inventors developed a method to ex vivo generated and expanded antigen specific Foxp3 expressing CD3+ TCRγδ+ unrestricted T cells, committed to exclusively exert regulatory activity, whichever culture condition of stimulation is. In particular, the present invention relates to a method for generating ex vivo γδ Foxp3+ regulatory T cells having the following phenotype: CD3+ TCRγδ+ Foxp3+.
