Chronic human norovirus (HuNoV) infections in immunocompromised patients result in severe disease, yet approved antivirals are lacking. RNA-dependent RNA polymerase (RdRp) inhibitors inducing viral mutagenesis display broad-spectrum in vitro antiviral activity, but clinical efficacy in HuNoV infections is anecdotal and the potential emergence of drug-resistant variants is concerning. Upon favipiravir

A tetravalent bispecific antibody outperforms the combination of its parental antibodies and neutralizes diverse SARS-CoV-2 variants Clin. Immunol. (IF 8.6) Pub Date : 2024-01-11 Abhishek Chiyyeadu, Girmay Asgedom, Matthias Bruhn, Cheila Rocha, Tom U. Schlegel, Thomas Neumann, Melanie Galla, Philippe Vollmer Barbosa, Markus Hoffmann, Katrin Ehrhardt, Teng-Cheong Ha, Michael Morgan, Clara T. Schoeder, Stefan Pöhlmann, Ulrich Kalinke, Axel Schambach
The devastating impact of COVID-19 on global health shows the need to increase our pandemic preparedness. Recombinant therapeutic antibodies were successfully used to treat and protect at-risk patients from COVID-19. However, the currently circulating Omicron subvariants of SARS-CoV-2 are largely resistant to therapeutic antibodies, and novel approaches to generate broadly neutralizing antibodies are

Short-chain fatty acids ameliorate experimental anti-glomerular basement membrane disease Clin. Immunol. (IF 8.6) Pub Date : 2024-01-11 Jing Liu, Qiu-hua Gu, Zhao Cui, Ming-hui Zhao, Xiao-yu Jia
Background Short-chain fatty acids (SCFAs), as the link between gut microbiota and the immune system, had been reported to be protective in many autoimmune diseases by the modulation of T cell differentiation. The pathogenic role of autoreactive Th1 and Th17 cells and the protective role of Treg cells in the pathogenesis of anti-GBM disease have been fully demonstrated. Thus, the present study aimed

Chemotherapy for a secondary malignancy nearly restores complete chimerism in an SCID-patient after HSCT Clin. Immunol. (IF 8.6) Pub Date : 2024-01-05 Felix I. Maier, Ansgar Schulz, Ingrid Furlan, Kerstin Felgentreff, Eva-Maria Jacobsen, Mehtap Sirin, Klaus Schwarz, Ulrich Pannicke, Jana Stursberg, Klaus-Michael Debatin, Manfred Hönig
For patients with inborn errors of immunity (IEI) and other inborn diseases, mixed donor chimerism is a well-accepted outcome of hematopoietic stem cell transplantation (HSCT). Cytoreductive chemotherapy for a secondary malignancy is a potential challenge for the stability of the graft function after HSCT. We report on a boy with X-SCID who developed Ewing sarcoma ten years after HSCT which was successfully

Better efficacy, lower recurrence rate and decreased CD8+TRM with guselkumab treatment for generalized pustular psoriasis: A prospective cohort study from China Clin. Immunol. (IF 8.6) Pub Date : 2024-01-05 Jiajing Lu, Dawei Huang, Nan Yang, Hui Qin, Yingyuan Yu, Xiaoyuan Zhong, Luyang Kong, Yuxiong Jiang, Jing Zhou, Yuling Shi
Generalized pustular psoriasis (GPP) is a severe and uncommon form of psoriasis, for which treatment options are limited. There is an urgent need to expand the treatment options for GPP. Currently, adalimumab, secukinumab, and guselkumab are considered effective for GPP, but there is a lack of prospective direct comparative studies on their efficacy for GPP. We conducted a prospective, single-center

Alterations in the innate and adaptive immune system in a real-world cohort of multiple sclerosis patients treated with ocrelizumab Clin. Immunol. (IF 8.6) Pub Date : 2024-01-06 L. Beckers, P. Baeten, V. Popescu, D. Swinnen, A. Cardilli, I. Hamad, B. Van Wijmeersch, S.J. Tavernier, M. Kleinewietfeld, B. Broux, J. Fraussen, V. Somers
B cell depletion by the anti-CD20 antibody ocrelizumab is effective in relapsing-remitting (RR) and primary progressive (PP) multiple sclerosis (MS). We investigated immunological changes in peripheral blood of a real-world MS cohort after 6 and 12 months of ocrelizumab. All RRMS and most PPMS patients (15/20) showed treatment response. Ocrelizumab not only reduced CD20+ B cells, but also numbers of

Guanylate binding protein 5 triggers NF-κB activation to foster radioresistance, metastatic progression and PD-L1 expression in oral squamous cell carcinoma Clin. Immunol. (IF 8.6) Pub Date : 2024-01-05 Hui-Wen Chiu, Che-Hsuan Lin, Hsun-Hua Lee, Hsiao-Wei Lu, Yu-Hsien Kent Lin, Yuan-Feng Lin, Hsin-Lun Lee
Radioresistance and metastasis are critical issues in managing oral squamous cell carcinoma (OSCC). Although immune checkpoint inhibitors (ICIs) has been recommended to treat OSCC, lacking useful biomarkers limited their anti-cancer effectiveness. We found that guanylate binding protein 5 (GBP5) is upregulated in primary tumors and associates with radioresistance in OSCC. GBP5 expression causally associated

Proteomic profiling of aqueous humor-derived exosomes in Vogt-Koyanagi-Harada disease and Behcet's uveitis Clin. Immunol. (IF 8.6) Pub Date : 2024-01-05 Yinan Zhang, Yang Deng, Shixiang Jing, Guannan Su, Na Li, Ziqian Huang, Wanyun Zhang, Zhijun Chen, Peizeng Yang
Vogt-Koyanagi-Harada (VKH) disease and Behcet's uveitis (BU) are the two major vision-threatening uveitis entities. This study performed the first label-free quantitative proteomics on aqueous humor-derived exosomes from 84 patients with VKH or BU to determine their potential roles. Sixty-five differentially expressed proteins (DEPs) and 40 DEPs were detected in the VKH and BU groups, respectively
