Neurotransmitter and metabolic effects of interferon-alpha in association with decreased striatal dopamine in a non-human primate model of cytokine-Induced depression

Inflammatory stimuli administered to humans and laboratory animals affect mesolimbic and nigrostriatal dopaminergic pathways in association with impaired motivation and motor activity. Alterations in dopaminergic corticostriatal reward and motor circuits have also been observed in depressed patients with increased peripheral inflammatory markers. The effects of peripheral inflammation on dopaminergic pathways and associated neurobiologic mechanisms and consequences have been difficult to measure in patients. Postmortem tissue (n = 11) from an established, translationally-relevant non-human primate model of cytokine-induced depressive behavior involving chronic interferon-alpha (IFN-a) administration was utilized herein to explore the molecular mechanisms of peripheral cytokine effects on striatal dopamine. Dopamine (but not serotonin or norepinephrine) was decreased in the nucleus accumbens (NAcc) and putamen of IFN-a-treated animals (p < 0.05). IFN-a had no effect on number of striatal neurons or dopamine terminal density, suggesting no overt neurodegenerative changes. RNA sequencing examined in the caudate, putamen, substantia nigra, and prefrontal cortical subregions revealed that while IFN-a nominally up-regulated limited numbers of genes enriching inflammatory signaling pathways in all regions, robust, whole genome-significant effects of IFN-a were observed specifically in putamen. Genes upregulated in the putamen primarily enriched synaptic signaling, glutamate receptor signaling, and inflammatory/metabolic pathways downstream of IFN-a, including MAPK and PI3K/AKT cascades. Conversely, gene transcripts reduced by IFN-a enriched oxidative phosphorylation (OXPHOS), protein translation, and pathways regulated by dopamine receptors. Unsupervised clustering identified a gene co-expression module in the putamen that was associated with both IFN-a treatment and low dopamine levels, which enriched similar inflammatory, metabolic, and synaptic signaling pathways. IFN-a-induced reductions in dopamine further correlated with genes related to excitotoxic glutamate, kynurenine, and altered dopamine receptor signaling (r = 0.78-97, p < 0.05). These findings provide insight into the immunologic mechanisms and neurobiological consequences of peripheral inflammation effects on dopamine, which may inform novel treatment strategies targeting inflammatory, metabolic or neurotransmitter systems in depressed patients with high inflammation.

Abstract:

Interferon alfa has activity against multiple myeloma (MM). Modakafusp alfa is an immunocytokine comprising 2 attenuated interferon alfa-2b molecules and an anti-CD38 immunoglobulin G4 antibody, targeting delivery of interferon alfa to CD38-expressing (CD38+) immune and myeloma cells. This phase 1/2 trial enrolled patients with relapsed/refractory multiple myeloma with ≥3 prior lines of treatment and refractory to, or intolerant of, ≥1 proteasome inhibitor and ≥1 immunomodulatory drug. During dose escalation, modakafusp alfa was administered at 10 doses in 4 schedules across 13 cohorts. The primary end point was safety for dose escalation, and overall response rate (ORR) for dose expansion. We enrolled 106 patients who had received a median of 6.5 lines of prior therapy; 84% of patients had myeloma previously refractory to an anti-CD38 antibody. The most feasible dosing schedule was every 4 weeks (Q4W), at which the maximum tolerated dose was 3 mg/kg. Among 30 patients treated at 1.5 mg/kg Q4W, the ORR was 43.3%, with a median duration of response of 15.1 months (95% confidence interval [CI], 7.1-26.1); median progression-free survival was 5.7 months (95% CI, 1.2-14). Grade ≥3 adverse events (AEs) occurred in 28 (93.3%) patients, the most common were neutropenia (66.7%) and thrombocytopenia (46.7%); infections were reported in 8 (26.7%) patients (including grade 3 in 4 [16.7%]). Modakafusp alfa therapy induced upregulation of the type 1 interferon gene signature score, increased CD38 receptor density in CD38+ cells, and innate and adaptive immune cell activation. Modakafusp alfa resulted in antitumor activity and immune activation in patients with MM. AEs were primarily hematologic. This trial was registered at www.clinicaltrials.gov as #NCT03215030.

[Advances in the diagnosis and treatment of thrombocytosis in children].

Review

作者: Xu, Yu-Ting ; Hu, Qun

Thrombocytosis is a common condition in children, classified into primary and secondary types. Secondary thrombocytosis is mainly caused by factors such as infection, anemia, iron deficiency, trauma, or surgical intervention, and it typically occurs without severe thrombosis or bleeding events. Platelet counts can return to normal after control of the primary factors, with favorable clinical outcomes. Primary thrombocytosis is mainly caused by myeloproliferative neoplasms such as polycythemia vera, essential thrombocythemia, and myelofibrosis, often accompanied by gene mutations in hematopoietic cells. In children, clinical manifestations are atypical compared to adults, with few thromboembolic or bleeding events. No special treatment is required for patients who are asymptomatic or have mild symptoms, and it is recommended to regularly monitor platelet counts. Antiplatelet therapy with aspirin can be considered for patients at risk of thrombosis or those with extreme thrombocytosis, and cytoreductive therapy can be performed when necessary, but the toxicities and side effects of drugs should be closely monitored. At present, hydroxyurea, interferon-alpha, and anagrelide are commonly used for cytoreductive therapy. This article provides an overview of the etiology, classification, clinical manifestations, diagnosis, and treatment of childhood thrombocytosis to guide healthcare professionals in treatment decisions.
