The FcεRI signaling pathway is involved in the pathogenesis of lacrimal gland benign lymphoepithelial lesions as shown by transcriptomic analysis.

ABSTRACT: This study aimed to analyze the role of the FcepsilonRI (FcεRI) signaling pathway in the pathogenesis of benign lymphoepithelial lesion of lacrimal gland (LGBLEL). Transcriptomic analysis was performed on LGBLEL and orbital cavernous hemangioma (CH) patients diagnosed via histopathology in Beijing Tongren Hospital, Capital Medical University, between July 2010 and October 2013. Four LGBLEL and three orbital CH patients, diagnosed between October 2018 and August 2019, were randomly selected as experimental and control groups, respectively. RT-PCR, immunohistochemical staining, and western blotting were used to verify genes and proteins related to the FcεRI signaling pathway. Transcriptomic analysis showed that the FcεRI signaling pathway was upregulated in the LGBLEL compared with the CH group. The mRNA expression levels of important genes including SYK, p38, JNK, PI3K, and ERK were significantly increased in the LGBLEL group (P = 0.0066, P = 0.0002, P = 0.0003, P < 0.0001, P < 0.0001, respectively). Immunohistochemical staining results showed that SYK, p38, and ERK were positively expressed in LGBLEL, while JNK and PI3K were not. The protein contents of P-SYK, P-p38, P-JNK, P-PI3K, and P-ERK were significantly higher in the LGBLEL than in the CH group (P = 0.0169, P = 0.0074, P = 0.0046, P = 0.0157, P = 0.0156, respectively). The FcεRI signaling pathway participates in the pathogenesis of LGBLEL.

Project description:BackgroundThe present study reviewed the clinicopathological features and outcomes of bilateral lacrimal gland lesions.MethodsThe data of 113 patients who underwent lacrimal gland biopsy at the West China Hospital of Sichuan University, China, between January 1, 2010, and December 31, 2021, are presented in this case series. The patients all presented with bilateral lacrimal gland lesions. The collected data included patient demographics, clinical features, the results of laboratory examinations, imaging presentations, histopathological diagnoses, treatments, and outcomes.ResultsThe mean age of the 113 enrolled patients was 47.4 ± 14.9 years (range, 11-77 years) with a predominance of females (54.9%, n = 62). The lacrimal gland was the source of the majority of biopsy tissue (98.2%, n = 111). The most prevalent etiology was immunoglobulin G4-related ophthalmic disease (IgG4-ROD) (32.7%, n = 37), followed by idiopathic orbital inflammation (IOI) (28.3%, n = 32), mucosa-associated lymphoid tissue (MALT) lymphoma (17.7%, n = 20), reactive lymphoid hyperplasia (RLH) (10.6%, n = 12), and mantle cell lymphoma (4.4%, n = 5). Patients with IOI were significantly younger than those with IgG4-ROD and MALT lymphoma (t = 2.932, P = 0.005; t = 3.865, P<0.001, respectively). Systemic symptoms were more prevalent among patients with IgG4-ROD (χ2 = 7.916, P = 0.005). The majority of patients were treated with surgery (53.1%, n = 60), with surgery combined with corticosteroid therapy (21.2%, n = 24) being the second most common treatment. The majority of patients (91.2%, n = 103) attained complete resolution, stable disease, or significant improvement.ConclusionIn conclusion, there are several aetiologies associated with bilateral lacrimal gland lesions, the most prevalent being IgG4-ROD, IOI, and MALT lymphoma. Systemic symptoms were more common in patients with IgG4-ROD. The majority of patients who presented with bilateral lesions of the lacrimal glands responded satisfactorily to treatment, with favorable results.
