  • Publication number: 20250254174
    Abstract: Security with dynamic privilege level assignment in a hybrid-cloud stack is provided. A request associated with a user is received. For the request, a mapping and an authority structure are retrieved, where the mapping identifies a plurality of services and the authority structure identifies requisite privilege levels of the plurality of services. For the user, an allowed privilege range is retrieved. A current privilege level is set to a minimum privilege level of the allowed privilege range. A requisite privilege level for the request is determined based on the requisite privilege levels of the plurality of services. In response to determining that the current privilege level is less than the requisite privilege level for the request, the current privilege level is escalated based on the allowed privilege range and the requisite privilege level for the request, and the request is processed using the escalated privilege level.

  • Publication number: 20240366671
    Abstract: A combined HER2 and MESO dual-target CAR-T vector, a construction method therefor and an application thereof in cancer are provided; specifically, a bispecific chimeric antigen receptor (CAR) containing HER2 scFv and MESO scFv, a 4-1BB co-stimulatory domain, and a CD3 activation domain is provided. The bispecific CAR-T cell has a significant killing effect on HER2-positive target cells and MESO-positive target cells and can improve on the tumor-killing effect of T cells; the cytokines produced have a super-additive effect, and compared with a single-target CAR-T, can better clear tumor cells, alleviate antigen escape caused by tumor heterogeneity, and further strengthen the ability of CAR-T cells to kill tumors.

  • Publication number: 20240240142
    Abstract: The present invention relates to a novel method for isolating and culturing dermal papilla cells. Particularly, in the isolation and culture method of the present invention, by culturing dermal papilla tissue isolated from the scalp under hypoxic conditions, dermal papilla cells separated from the dermal papilla tissue are rapidly attached to a culture plate, thus having the effect of shortening the period of establishing (harvesting) dermal papilla cells, and the isolated and cultured dermal papilla cells have immunocompatibility, and thus can be effectively used for the allogeneic transplantation of dermal papilla cells.
