The phrase "activates a type" is correct and usable in written English.
It can be used in contexts where you are describing a process or action that triggers a specific category or classification.
Example: "The new software update activates a type of security protocol that enhances data protection."
Alternatives: "triggers a category" or "initiates a kind".
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].
When interactions between CA and CypA or CPSF6 are prevented, such as by mutating the viral capsid, HIV-1 triggers DNA sensors and activates a type 1 IFN response, leading to suppression of replication.
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].
1, 2 Angiotensin-II (A-II), the major active peptide, activates A-II type 1 receptor (AT1R) to provide vasoconstriction and hypertension.
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].
Its principal action is to activate ionotropic A-type GABA receptors (GABAARs), leading to an inward flow of Cl− and a hyperpolarizing postsynaptic response.
IFN-γ also helps fight bacterial infection by activating macrophages, a type of white blood cell that gobbles up microbes.
A few years ago, Chawla's group had reported that cold exposure activated macrophages, a type of immune cell, in white adipose tissue.
This is consistent with the observation that lab-generated strains of nifurtimox-resistant T. brucei (nifurtimox is activated by a type I NTR) were cross resistant to fexinidazole but showed no change in sensitivity to (S -PA-824 (20).
