| 1 | Unique immunological profile in patients with COVID-19显示文摘The relationship between severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)and host immunity is poorly understood.We performed an extensive analysis of immune responses in 32 patients with severe COVID-19,some of whom succumbed A control population of healthy subjects was included.Patients with COVID-19 had an altered distribution of peripheral blood lymphocytes,with an increased proportion of mature natural killer(NK)cells and low T-cell numbers.NK cells and CD8^(+)T cells overexpressed T-cellimmunoglobulin and mucin domain-3(TIM-3)and CD69.NK cell exhaustion was attested by increased frequencies of programmed cell death protein 1(PD-1)positive cells and reduced frequencies of natural killer group 2 member D(NKG2D)-,DNAX accessory molecule-1(DNAM-1)-and sialic acid-binding Ig-like lectin 7(Siglec-7)-expressing NK cells,associated with a reduced ability to secrete interferon(IFN)γ.Patients with poor outcome showed a contraction of immature CD56^(bright) and an expansion of mature CD57^(+)F_(CEI)Rlγ^(eng) adaptive NK cells compared to survivors.Increased serum levels of IL-6 were also more frequently identified in deceased patients compared to survivors.Of note,monocytes secreted abundant quantities of IL-6,IL-8,and IL-1β which persisted at lower levels several weeks after recovery with concomitant normalization of CD69,PD-1 and TIM-3 expression and restoration of CD8^(+)T cell numbers.A hyperactivated/exhausted immune response dominate in severe SARS-CoV-2 infection,probably driven by an uncontrolled secretion of inflammatory cytokines by monocytes.These findings unveil a unique immunological profile in COVID-19 patients that will help to design effective stage-specific treatments for this potentially deadly disease. | Stefania Varchetta Dalila Mele Barbara Olivier Stefania Mantovani Serena Ludovisi Antonella Cerino Raffaele Bruno Alberto Castelli Mario Mosconi Marco Vecchia Silvia Roda Michele Sachs Catherine Klersy Mario U.Mondelli | 2021 | Cellular & Molecular Immunology2021，18，3： | 1 |

| 3 | Lipid catabolism and mitochondrial uncoupling are stimulated in brown adipose tissue of amyotrophic lateral sclerosis mouse models显示文摘Amyotrophic lateral sclerosis (ALS) is a fatal motor neuron disease typically leading to death within 5 years from symptom onset. ALS familial forms are associated with mutations in several genes, including Superoxide Dismutase 1 (SOD1) and Fused in Sarcoma (FUS). Although genes linked to ALS participate in disparate biological processes, ALS genetic variants largely trigger shared pathogenic events such as oxidative stress, protein aggregation and defects in RNA processing. Moreover, ALS patients show systemic hypermetabolism that leads to increased energy expenditure at rest and thus weight loss during the disease course.1 ALS hypermetabolic phenotype and weight loss have been extensively characterized in mice bearing the G93A substitution in SOD1 protein (SOD1-G93A), which exhibit skeletal-muscle metabolic reprogramming before disease onset. | Fabio Ciccarone Serena Castelli Giacomo Lazzarino Silvia Scaricamazza Renata Mangione Sergio Bernardini Savina Apolloni Nadia D'Ambrosi Alberto Ferri Maria Rosa Ciriolo | 2023 | Genes & Diseases2023，10，2： | 0 |
