Rora, also known as retinoic acid receptor-related orphan receptor-α, is a transcription factor involved in multiple biological processes. It plays a role in regulating circadian rhythms, inflammation, metabolism, and cellular development. Rora is associated with pathways such as those related to cell differentiation, immune regulation, and anti-oncogenesis [1-10].

In a CD4-conditional Rora-knockout mouse model, Rora was found to be important for controlling lung inflammation induced by Nippostrongylus brasiliensis infection in CD4+ T cells, suggesting it is a negative regulator of the immune system [1]. In neuron-specific RORA null mice, prenatal RORA deficiency mimicked maternal diabetes-mediated autism-like behavior, indicating RORA's role in autism-like offspring development [2]. In Roraloxp/loxp Mx-1-Cre mice where Rora was deleted in hematopoietic cells post Pipc induction, there was an accumulation of B cells, showing Rora's role in B cell development [3].

In conclusion, Rora is crucial in various biological processes. Through gene knockout mouse models, its role in immune regulation, autism-like behavior, and B cell development has been revealed. These findings contribute to understanding the mechanisms underlying related diseases and potentially provide new therapeutic targets.
