Non-p-NBD manifests as intracranial aneurysm, cerebral venous thrombosis, peripheral nervous system injuries, and mixed parenchymal and non-parenchymal disease. p-NBD is pathologically characterized by perivasculitis presenting with cerebrospinal fluid (CSF) pleocytosis, elevated total protein, and central nervous system (CNS) infiltration of macrophages and neutrophils, which are subdivided into acute and chronic progressive stages according to relapsing-remitting courses and responses to steroids. The diagnosis of NBD depends heavily on clinical features and magnetic resonance imaging (MRI) findings. The lack of laboratory biomarkers has hindered standard diagnostics. CSF interleukin (IL)-6 is the most investigated dimension of NBD and correlates with NBD activity, therapeutic responses, and prognosis. Further investigations have focused on inflammatory biomarkers that reflect the activation of innate and adaptive immune responses. Higher levels of CSF migration inhibitory factor and immunosuppressive acidic protein indicated the activation of macrophages in the CNS; increased IL-17, IL-10, T-bet/GATA-3, and retinoic acid related orphan receptor (ROR)-γt/Foxp3 ratios, marking the disrupted scale of the Th1/Th2 and Th17/Treg axis; and elevated B-cell activating factor of the TNF family (BAFF) and IgA/IgM intrathecal synthesis, suggesting that B cells play a dominant role in NBD.

Previously, we demonstrated the accumulation of senescent cells in skin lesions of patients with LCL. Moreover, lesional transcriptomic analyses revealed a robust co-induction of senescence and pro-inflammatory gene signatures, highlighting the critical role of senescent T cells in orchestrating pathology. In this work we hypothesized that senescent cells might operate differently among the ATL spectrum, potentially influencing immunopathological mechanisms and clinical outcome. We analysed previously published RNA-Seq datasets of skin biopsies of healthy subjects and lesional skin from DCL patients, LCL patients, and LCL patients that, after treatment, progressed to mucosal leishmaniasis (MLP). Our findings demonstrate a robust presence of a CD8 T-cell signature associated with both LCL and MLP lesions. Moreover, both inflammatory and cytotoxic signatures were significantly upregulated, showing a strong increase in MLP and LCL groups, but not DCL. The senescence signature was elevated between LCL and MLP groups, representing the only distinguishable signature of immunopathology between them. Interestingly, our analyses further revealed the senescence signature's capacity to predict progression from LCL to mucosal forms, which was not observed with other signatures. Both the senescence-signature score and specific senescence-associated genes demonstrated an increased capacity to predict mucosal progression, with correct predictions exceeding 97% of cases. Collectively, our findings contribute to a comprehensive understanding of immunosenescence in ATL and suggest that senescence may represent the latest and most important signature of the immunopathogenisis.

Nevertheless, the effect of consuming DHA on CP/CPPS is still uncertain. Therefore, we established an experimental autoimmune prostatitis (EAP) model, which is frequently employed in CP/CPPS research. This study aimed to investigate the effects of dietary docosahexaenoic acid (DHA) intake on EAP and to elucidate the underlying mechanisms involved. During the establishment of EAP, non-obese diabetic (NOD) mice were administered either DHA-enriched water or conventional water. The severity of EAP and the Th17 cell responses were evaluated. Furthermore, we investigated the impact of the PPARγ inhibitor GW9662 and the NF-κB activator PMA on mice with EAP that were administered DHA. The findings demonstrated that consumption of DHA reduced the severity of EAP and inhibited the production of Th17 cells. DHA was found to hinder the development of Th17 cells through the PPARγ/NF-κB/IL-17A pathway, as demonstrated by in vitro assays. The administration of GW9662 and PMA resulted in an increase in Th17 cell production, worsening the symptoms of EAP alleviated by the consumption of DHA. The present study revealed that the consumption of DHA mitigates EAP by stimulating the PPARγ/NF-κB/IL-17A pathway, thereby influencing the process of Th17 cell differentiation.
