Crossover or non-crossover outcomes : tailored processing of homologous recombination intermediates

Sanchez, Aurore ; Reginato, Giordano ; Cejka, Petr

In: Current opinion in genetics & development, 2021, vol. 71, p. 39-47

DNA breaks may arise accidentally in vegetative cells or in a programmed manner in meiosis. The usage of a DNA template makes homologous recombination potentially error-free, however, recombination is not always accurate. Cells possess a remarkable capacity to tailor processing of recombination intermediates to fulfill a particular need. Vegetatively growing cells aim to maintain genome...

Axillary dissection is a highly mobile procedure with severe lymphatic consequences. The off-label application of fibrin sealants in the axilla, with the sole aim to eliminate dead space and to provoke sealing of the disrupted lymphatic vessels at the end of axillary dissection, is an experimental procedure to reduce lymphatic morbidity. The aim of our systematic review and meta-analysis is to ...

Glomerular macrophages in human auto- and allo-immune nephritis

Moll, Solange ; Angeletti, Andrea ; Scapozza, Leonardo ; Cavalli, Andrea ; Ghiggeri, Gian Marco ; Prunotto, Marco

In: Cells, 2021, vol. 10, no. 3, p. 19 p

Macrophages are involved in tissue homeostasis. They participate in inflammatory episodes and are involved in tissue repair. Macrophages are characterized by a phenotypic heterogeneity and a profound cell plasticity. In the kidney, and more particularly within glomeruli, macrophages are thought to play a maintenance role that is potentially critical for preserving a normal glomerular structure....

Higher-order connections between stereotyped subsets : implications for improved patient classification in CLL

Agathangelidis, Andreas ; Chatzidimitriou, Anastasia ; Gemenetzi, Katerina ; Giudicelli, Veronique ; Karypidou, Maria ; Plevova, Karla ; Davis, Zadie ; Yan, Xiao-Jie ; Jeromin, Sabine ; Schneider, Christof ; Bredo-Pedersen, Lone ; Tschumper, Renee C. ; Sutton, Lesley-Ann ; Baliakas, Panagiotis ; Scarfò, Lydia ; van Gastel, Ellen J. ; Armand, Marine ; Tausch, Eugen ; Biderman, Bella ; Baer, Constance ; Bagnara, Davide ; Navarro, Alba ; Langlois de Septenville, Anne ; Guido, Valentina ; Mitterbauer-Hohendanner, Gerlinde ; Dimovski, Aleksandar ; Brieghel, Christian ; Lawless, Sarah ; Meggendorfer, Manja ; Braazdilova, Kamila ; Ritgen, Matthias ; Facco, Monica ; Tresoldi, Cristina ; Visentin, Andrea ; Patriarca, Andrea ; Catherwood, Mark ; Bonello, Lisa ; Sudarikov, Andrey ; Vanura, Katrina ; Roumelioti, Maria ; Skuhrova-Francova, Hana ; Moysiadis, Theodoros ; Veronese, Silvio ; Giannopoulos, Krzysztof ; Mansouri, Larry ; Karan-Djurasevic, Teodora ; Sandaltzopoulos, Raphael ; Bödör, Csaba ; Fais, Franco ; Kater, Arnon ; Panovska, Irina ; Rossi, Davide ; Alshemmari, Salem ; Panagiotidis, Panagiotis ; Costeas, Paul ; Espinet Solà, Blanca ; Antic, Darko ; Foroni, Letizia ; Montillo, Marco ; Trentin, Livio ; Stavroyianni, Niki ; Gaidano, Gianluca ; Francia di Celle, Paola ; Niemann, Carsten ; Campo, Elias ; Anagnostopoulos, Achilles ; Pott, Christiane ; Fischer, Kirsten ; Hallek, Michael ; Oscier, David ; Stilgenbauer, Stephan ; Haferlach, Claudia ; Jelinek, Diane ; Chiorazzi, Nicholas ; Pospisilova, Sarka ; Lefranc, Marie-Paule ; Kossida, Sofia ; Langerak, Anton W. ; Belessi, Chrysoula ; Davi, Frederic ; Rosenquist, Richard ; Ghia, Paolo ; Stamatopoulos, Kostas

In: Blood, 2020, vol. 137, no. 10, p. 1365–1376

Chronic lymphocytic leukemia (CLL) is characterized by the existence of subsets of patients with (quasi)identical, stereotyped B cell receptor immunoglobulins (BcR IG). Patients in certain major stereotyped subsets often display remarkably consistent clinicobiological profiles, suggesting that the study of BcR IG stereotypy in CLL has important implications for understanding disease...

In: Cell, 2016, vol. 166, no. 3, p. 596-608

Influenza virus remains a threat because of its ability to evade vaccine-induced immune responses due to antigenic drift. Here, we describe the isolation, evolution, and structure of a broad-spectrum human monoclonal antibody (mAb), MEDI8852, effectively reacting with all influenza A hemagglutinin (HA) subtypes. MEDI8852 uses the heavy-chain VH6-1 gene and has higher potency and breadth when...

Identification and structure of a multidonor class of head-directed influenza-neutralizing antibodies reveal the mechanism for its recurrent elicitation

Sao-Fong Cheung, Crystal ; Fruehwirth, Alexander ; Paparoditis, Philipp Carl Georg ; Shen, Chen-Hsiang ; Foglierini, Mathilde ; Joyce, M. Gordon ; Leung, Kwanyee ; Piccoli, Luca ; Rawi, Reda ; Silacci-Fregni, Chiara ; Tsybovsky, Yaroslav ; Verardi, Raffaello ; Wang, Lingshu ; Wang, Shuishu ; Yang, Eun Sung ; Zhang, Baoshan ; Zhang, Yi ; Chuang, Gwo-Yu ; Corti, Davide ; Mascola, John R. ; Shapiro, Lawrence ; Kwong, Peter D. ; Lanzavecchia, Antonio ; Zhou, Tongqing

In: Cell reports, 2020, vol. 32, no. 9, p. 12 p

Multidonor antibodies are of interest for vaccine design because they can in principle be elicited in the general population by a common set of immunogens. For influenza, multidonor antibodies have been observed against the hemagglutinin (HA) stem, but not the immunodominant HA head. Here, we identify and characterize a multidonor antibody class (LPAF-a class) targeting the HA head. This class...
