High-affinity monoclonal antibody 5D5 does not inhibit Plasmodium sporozoites

Elaine Thai, Giulia Costa, Anna Weyrich, Rajagopal Murugan, David Oyen, Yevel Flores-Garcia, Katherine Prieto, Alexandre Bosch, Angelo Valleriani, Nicholas C. Wu, Tossapol Pholcharee, Stephen W. Scally, Ian A. Wilson, Hedda Wardemann, Jean-Philippe Julien, Elena A. Levashina

Molecular characterization of inhibitory and non-inhibitory antibodies contributes to vaccine design. Here, we show that the high-affinity mAb 5D5 against the PfCSP N-terminus of sporozoites does not inhibit Pf invasion. This information is critical for the prioritization of functional sites of vulnerability to include in next-generation malaria immunogen designs.

Morphology of macrophages is prognostic in CLM

Matteo Donadon, Guido Torzilli, Nina Cortese, Cristiana Soldani, Luca Di Tommaso, Barbara Franceschini, Roberta Carriero, Marialuisa Barbagallo, Alessandra Rigamonti, Achille Anselmo, Federico Simone Colombo, Giulia Maggi, Ana Lleo, Javier Cibella, Clelia Peano, Paolo Kunderfranco, Massimo Roncalli, Alberto Mantovani, Alberto Mantovani, Federica Marchesi, Federica Marchesi

Morphometric characterization of TAMs in human colorectal liver metastases captures individual populations, corresponding to single-cell clusters and associated with distinct clinical outcome and transcriptional profiles. Quantitative analysis of macrophage morphology can serve as a simple readout of functional diversity with prognostic significance.

Plasma cell development without Pax5 repression

Grace J. Liu, Markus Jaritz, Miriam Wöhner, Benedikt Agerer, Andreas Bergthaler, Stephen G. Malin, Meinrad Busslinger

Due to cross-antagonism of the B cell factor Pax5 and plasma cell regulator Blimp1, it was hypothesized that plasma cells develop only upon Pax5 repression by Blimp1. Unexpectedly, Liu et al. show that ectopic Pax5 expression in plasma cells does not interfere with their development and function.

Macrophages promote bone metastases

Ruo-Yu Ma, Hui Zhang, Xue-Feng Li, Cheng-Bin Zhang, Cigdem Selli, Giulia Tagliavini, Alyson D. Lam, Sandrine Prost, Andrew H. Sims, Hai-Yan Hu, Tianlei Ying, Zhan Wang, Zhaoming Ye, Jeffrey W. Pollard, Bin-Zhi Qian

This study identifies a novel population of CD204+IL4R+ bone metastasis–associated macrophages (BoMAMs) in mouse models and patient samples. These BoMAMs, derived from CCR2-recruited monocytes but not from CD169+ resident macrophages, significantly promote metastatic outgrowth of breast cancer in vivo.

NCKAP1L deficiency

Carla Noemi Castro, Michelle Rosenzwajg, Raphael Carapito, Mohammad Shahrooei, Martina Konantz, Amjad Khan, Zhichao Miao, Miriam Groß, Thibaud Tranchant, Mirjana Radosavljevic, Nicodème Paul, Tristan Stemmelen, Fabien Pitoiset, Aurélie Hirschler, Benoit Nespola, Anne Molitor, Véronique Rolli, Angélique Pichot, Laura Eva Faletti, Bruno Rinaldi, Sylvie Friant, Mark Mednikov, Hatice Karauzum, M. Javad Aman, Christine Carapito, Claudia Lengerke, Vahid Ziaee, Wafaa Eyaid, Stephan Ehl, Fayhan Alroqi, Nima Parvaneh, Seiamak Bahram, Seiamak Bahram

Biallelic mutations in NCKAP1L, a regulator of the actin cytoskeleton, cause immunodeficiency, lymphoproliferation, and hyperinflammation with features of hemophagocytic lymphohistiocytosis. Impaired immune synapse formation, early T cell activation and leading edge formation, and defective neutrophil migration characterize this novel “actinopathy.”

Serum HBsAg has minimal impact on CD8 + T cells

Valeria Fumagalli, Pietro Di Lucia, Valentina Venzin, Elisa B. Bono, Robert Jordan, Christian R. Frey, William Delaney, Francis V. Chisari, Luca G. Guidotti, Luca G. Guidotti, Matteo Iannacone, Matteo Iannacone

Antibody-mediated clearance of circulating HBsAg has minimal impact on the expansion of HBV-specific CD8+ T cells undergoing intrahepatic priming. It does not alter their differentiation into dysfunctional cells, nor does it enhance their functional restoration by immunotherapeutic strategies.

NOTCH3 in mesenchymal colorectal cancer

Julia Varga, Adele Nicolas, Valentina Petrocelli, Marina Pesic, Abdelrahman Mahmoud, Birgitta E. Michels, Emre Etlioglu, Diego Yepes, Björn Häupl, Paul K. Ziegler, Katrin Bankov, Peter J. Wild, Stefan Wanninger, Hind Medyouf, Henner F. Farin, Sabine Tejpar, Thomas Oellerich, Jürgen Ruland, Christian W. Siebel, Florian R. Greten

Varga et al. describe a novel genetically modified mouse model of human, poor-prognosis mesenchymal colorectal cancer. Using this model, they identify NOTCH3 as a potential therapeutic target for this specific colorectal cancer subtype.
