Monoamine oxidase A (MAO A) is the critical enzyme to degrade serotonin in the brain and the knockout mouse exhibits hyperserotonemia and abnormalities that are observed in autism spectrum disorder (ASD). Thus, the MAO A knockout mouse is a valuable model for studying neurological and behavioral impairments in ASD. Based on the immune dysfunction hypothesis, dysregulated humoral immunity may cause neurological impairments.

This study aims to discover novel autoantibodies against tumor-associated antigens (TAAs) and establish diagnostic models for assisting in the diagnosis of lung cancer and discrimination of pulmonary nodules (PNs). Ten autoantibodies to TAAbs (TAAbs) were discovered by means of protein microarray and their serum level was also higher in 212 LC patients than that in 212 NC of validation cohort 1 (P < 0.05). The model 1 comprising 4 TAAbs and CEA reached an AUC of 0.813 (95%CI: 0.762–0.864) for diagnosing LC from normal individuals.

Background: IgM and IgG autoantibodies are present in healthy humans and there are also unique autoantibodies that make up the majority of autoantibodies present in the human body. The primary objective of this study was to identify proteins that are consistently expressed at baseline levels in healthy patients, with the intention of establishing a set of shared or common proteins that can be targeted for further investigation in future research endeavors.

HuProt Autoantibodies: The identification of the high-efficiency and non-invasive biomarkers for hepatocellular carcinoma (HCC) detection is urgently needed. This study aims to screen out potential autoantibodies to tumor-associated antigens (TAAbs) and to assess their diagnostic value for HCC. Fifteen potential TAAbs were screened out from the Human Proteome Microarray by 30 HCC sera and 22 normal control sera, of which eight passed multiple-stage validations by ELISA with a total of 1625 human serum samples from normal controls (NCs) and patients with HCC, liver cirrhosis, chronic hepatitis B, gastric cancer, esophageal cancer, and colorectal cancer.
IOTECH Immuno-oncology and Technology
Immunosenescence is a progressive remodeling of immune functions with a multifactorial etiology including aging and chronic antigenic stressors (inflammation, infections, cancer). We showed that a high pretreatment SIP (CD28–CD57+KLRG1+CD8+ circulating T cells>39.5%, SIP+) was associated with resistance to ICB in patients with aNSCLC. Chronic viral infections may speed up immune aging, especially CMV which affects blood T cells phenotype (loss of CD28, overexpression of CD57). We aimed to assess antiviral serological profile and its association with SIP status.

Pre-existing immunity that describes the endogenous tumor-specific adaptive immunity, before treatment may represent a valuable novel predictive biomarker for ICI treatment. In this study we estimate the potential value of pre-existing cancer-antigen specific CD8+ T cells as circulating predictive biomarkers. Additionally, we evaluate the major differences of known immune cell phenotypes between Pre-existing positive (PreI+) and Pre-existing negative (PreI-) NSCLC patients in circulation.

HuProt Autoantibodies: Colorectal cancer (CRC) has been reported as the second leading cause of cancer death worldwide. The 5-year annual survival is around 50%, mainly due to late diagnosis, striking necessity for early detection. This study aims to identify autoantibody in patients’ sera for early screening of cancer.

Pediatric Evans Syndrome (pES) is a rare autoimmune disorder characterized mainly with the co-occurrence of autoimmune hemolytic anemia and immune thrombocytopenia. Although around 40% of patients with pES have known genetic variants associated with inborn errors in immunity (IEI), the underlying immune anomalies especially B cell dysregulation are poorly understood. In our recent study, when compared to single lineage cytopenia such as chronic immune thrombocytopenia (cITP), we showed that patients with pES are characterized by abnormal expansion of circulating T-follicular helper cells (cTfh), increased T-cell activation, decreased naïve CD4+ T as well as class-switched memory B (CSMB) cells (Kumar et al., Blood 2022).

HuProt Small Molecule: Following central nervous system (CNS) injury, the investigation for neuroinflammation is vital because of its pleiotropic role in both acute injury and long-term recovery. Agmatine (Agm) is well known for its neuroprotective effects and anti-neuroinflammatory properties. However, Agm’s mechanism for neuroprotection is still unclear. We screened target proteins that bind to Agm using a protein microarray; the results showed that Agm strongly binds to interferon regulatory factor 2 binding protein (IRF2BP2), which partakes in the inflammatory response.
Clinical and Translational Medicine
Viral infection is a major cause of morbidity in children with mitochondrial disease (MtD). As a result, families with children with MtD are highly adherent to risk mitigation behaviours (RMBs) advised by the Centers for Disease Control and Prevention during the COVID-19 pandemic that can modulate infection risk.
