Pilra-flox Mouse

Pilra, or paired immunoglobulin-like type 2 receptor alpha, is a cell-surface inhibitory receptor. It plays a role in regulating immune responses, and is involved in pathways related to inflammation and immunity [2,5]. It has significance in maintaining CD8+ T cell quiescence through interaction with CD8α [4]. Additionally, it is an entry co-receptor for herpes simplex virus-1 [1].

Genetically, Pilra has been associated with several diseases. In Alzheimer's disease (AD), the Pilra-A allele (rs1859788 A > G) shows negative interactions with APOE risk variants and GM17, suggesting it modifies the effect of these high-risk variants on future AD risk [1]. Also, the R78 (rs1859788) variant correlates with higher HSV-1-specific IgG titers in AD patients [3]. In atrial fibrillation, Pilra is closely related to multiple types of immune cell infiltration, which may be associated with the disease and could be a novel intervention target [2]. In pan-cancer analysis, Pilra was significantly dysregulated and mutated, impacting patient prognosis, immune cell infiltration, and cancer immunotherapy outcomes [5].

In conclusion, Pilra is a key regulator in immune-related functions. Its study, especially through genetic associations in models, has provided insights into its role in diseases such as Alzheimer's disease, atrial fibrillation, and cancer. Understanding Pilra's functions can potentially offer new directions for therapeutic interventions in these disease areas.
