The phrase "activate a type" is correct and usable in written English.
It can be used in contexts where you are referring to enabling or initiating a specific category or classification of something, such as software features or settings.
Example: "To proceed with the installation, you need to activate a type of user account that has administrative privileges."
Alternatives: "enable a category" or "turn on a type".
Parvatiyar, K. et al. The helicase DDX41 recognizes the bacterial secondary messengers cyclic di-GMP and cyclic di-AMP to activate a type I interferon immune response.
Here, they activate a type of regulatory immune cell, which dampens the immune system's response to the peanut protein.
siRNAs and the vectors used to deliver them have previously been shown to induce non-specific effects in cells and in particular to activate a type 1 IFN response [ 22- 25].
RIG-1 and MDA5 undergo conformational changes upon binding to viral RNA, exposing an N-terminal CARD that interacts with and activates MAVS, which in turn activates a type I interferon response.
In fact, infection by Helicobacter pylori activates a type I IFN response through a NOD1- and NOD2-dependent mechanism, leading to Stat1 (signal transducer and activation of transcription 1) activation and further clearance of bacterial burden [ 54].
In neurons, for instance, CB1 signals through Gi/o proteins, inhibits voltage gated Ca++ channels and activates A-type and inwardly rectifying K+ currents [ 24].
These findings support the view that even in patients with ovarian cancer in progression after multiple regimens of chemotherapy, presentation of SCGB2A1 by DCs is still able, at least in vitro, to activate a strong type 1 T-cell response, and that type 1 cytokine expression is associated with high cytotoxic activity against the autologous tumour cells by CD8+ T cells.
An APC-mimetic scaffold that was engineered to activate a specific type of CAR-T cell was able to generate higher numbers of the modified T cells over longer periods of culture than analogously designed expansion beads, and the resulting cells were similarly effective in killing the lymphoma cells in the mice.
The goal of this paper is to find all substructures within a graph (G = (V,E)) that must be excited in order to activate a particular type of cell assembly that will be defined in this section, the k-assembly.
TSHβ stimulation of DIO2 on LPs elevates T3 in specific neural sites, and this change has been shown experimentally to activate a summer-type physiology.
More importantly, the elevated expression of CD1d was coupled to the enhanced capacity to activate a CD1d-dependent cell type, the iNKT (invariant natural killer T) cells (Szatmari et al, 2004).
