COVID-19 in the years 2020 to 2022 in Germany: effects of comorbidities and co-medications based on a large-scale database analysis by Roland Linder, Jonas Peltner, Anatoli Astvatsatourov, Willy Gomm, Britta Haenisch

“…Study cohort 2 included 27,238 patients (13,619 patients hospitalised with COVID-19 and 13,619 control patients with an outpatient COVID-19 diagnosis). Immunodeficiencies and use of immunosuppressives were strongest risk modifying factors for hospitalization in both study populations. …”

Oncolytic peptide LTX-315 induces anti-pancreatic cancer immunity by targeting the ATP11B-PD-L1 axis by Meng Wang, Xing Huang, Tingbo Liang, Tianyu Tang, Gang Zhang, Minghao Lu, Zhengtao Hong, Junming Huang, Xiao Zhi

“…This study aimed to demonstrate the potential effect and mechanism of LTX-315 in PD-L1 inhibition-induced anti-pancreatic cancer immunity.Methods Both immunodeficient and immunocompetent mouse models were used to evaluate the therapeutic efficacy of monotherapy and combination therapy. …”

CD4 CAR-T cells targeting CD19 play a key role in exacerbating cytokine release syndrome, while maintaining long-term responses by Alice Bergamini, Barbara Camisa, Attilio Bondanza, Fabio Ciceri, Chiara Bonini, Monica Casucci, Beatrice Greco, Camilla Bove, Silvia Arcangeli, Laura Falcone, Rita El Khoury, Anna De Lucia

“…To this aim, we took advantage of immunodeficient mice reconstituted with a human immune system (HuSGM3) and engrafted with the B-cell acute lymphoblastic leukemia cell line NALM-6, a model that allows to thoroughly study efficacy and toxicity profiles of CD19 CAR-T cell products.Results CD4 CAR-T cells showed superior proliferation and activation potential, which translated into stronger stimulation of myeloid cells, the main triggers of adverse events. …”

Electrochemotherapy with bleomycin, oxaliplatin, or cisplatin in mouse tumor models, from tumor ablation to in situ vaccination by Katja Uršič Valentinuzzi, Katja Uršič Valentinuzzi, Urška Kamenšek, Urška Kamenšek, Simona Kranjc Brezar, Chloe Heranney, Chloe Heranney, Tilen Komel, Tilen Komel, Simon Buček, Simon Buček, Maja Čemažar, Maja Čemažar, Gregor Serša, Gregor Serša

“…Through histological analyses and the use of immunodeficient and metastatic (for abscopal effect) mouse models, we identified and compared both the cytotoxic and immunological components of ECT’s antitumor efficiency, such as immunologically recognizable cell deaths (immunogenic cell death and necrosis) and immune infiltrate (CD11+, CD4+, CD8+, GrB+).ResultsDifferences in immunological involvement after equieffective intratumoral ECT were highlighted by variable kinetics of immunologically recognizable cell deaths and immune infiltrate across the studied tumor models. …”

Longitudinal immunogenicity cohort study of SARS-CoV-2 mRNA vaccines across individuals with different immunocompromising conditions: heterogeneity in the immune response and cruci... by Annalisa Ciabattini, Elena Pettini, Fabio Fiorino, Jacopo Polvere, Simone Lucchesi, Chiara Coppola, Simone Costagli, Gabiria Pastore, Anna Sicuranza, Monica Tozzi, Arianna Lippi, Francesca Panza, Monica Bocchia, Alessandro Bucalossi, Guido Garosi, David Bennett, Sonia Bernazzali, Massimiliano Fabbiani, Francesca Montagnani, Donata Medaglini

“…Summary: Background: Individuals with primary and secondary immunodeficiencies, being more susceptible to infections, are a priority for vaccination. …”

CD32B1, a versatile non-signaling antibody-binding scaffold for enhanced T cell adhesion to tumor stromal cognate antigens by Sara W. Feigelson, Tali Dadosh, Nehora Levi, Anita Sapoznikov, Hadas Weinstein-Marom, Hadas Weinstein-Marom, Dayana Blokon-Kogan, Dayana Blokon-Kogan, Yahel Avraham, Tamar Unger, Gideon Gross, Gideon Gross, Rony Dahan, Ronen Alon

“…The molecule, termed mSA2-CD8h-tILCD32B1, was also successfully expressed in T cells, readily and stably bound biotinylated IgG mAbs in vitro and once decorated with the biotin labeled mAbs, conferred the T cells with high adhesiveness to multiple surface-coated antigens. mSA2-CD8h-tILCD32B1 expressing human T cells decorated ex vivo with a biotin-labeled mAb retained the antibody for hours after accumulation inside breast tumors implanted in immunodeficient recipient mice. Our results collectively suggest that a non-signaling CD32B1 can be used as a versatile scaffold for mAb decoration of T cells. …”

Analysis of early efficacy and immune reconstitution after autologous hematopoietic stem cell transplantation in multiple myeloma by Kaili Chen, Huixin Liang, Zezhong Yu, Guangyao Guo, Huijian Zheng, Yun Huang, Liping Liu, Jie Lin, Jinlan Long, Renyao Pan, Xi Chen, Changgui Wang, Wenjie Zhang, Zhenshu Xu

“…Auto-HSCT can promote prolonged remission in patients with MM and also overcome some high-risk factors to achieve superior efficacy in group R-ISS II-III. Patients were immunodeficient before transplantation and auto-HSCT facilitated immune reconstitution.…”

Human GM-CSF/IL-3 enhance tumor immune infiltration in humanized HCC patient-derived xenografts by Kelley Weinfurtner, David Tischfield, George McClung, Jennifer Crainic, John Gordan, Jing Jiao, Emma E. Furth, Wuyan Li, Erena Tuzneen Supan, Gregory J. Nadolski, Stephen J. Hunt, David E. Kaplan, Terence P.F. Gade

“…Leveraging xenograft tumors derived from patients with unresectable HCCs and a commercially available immunodeficient mouse strain that expresses human GM-CSF and IL-3, we demonstrate a novel but accessible approach for modeling the HCC tumor microenvironment.…”
