Antibody-guided vaccine design : identification of protective epitopes

Lanzavecchia, Antonio ; Frühwirth, Alexander ; Perez, Laurent ; Corti, Davide

In: Current opinion in immunology, 2016, vol. 41, no. August, p. 62-67

In the last decade, progress in the analysis of the human immune response and in the isolation of human monoclonal antibodies have provided an innovative approach to the identification of protective antigens which are the basis for the design of vaccines capable of eliciting effective B-cell immunity. In this review we illustrate, with relevant examples, the power of this approach that can...

Dissecting human antibody responses: useful, basic and surprising findings

Lanzavecchia, Antonio

In: EMBO molecular medicine, 2018, vol. 10, p. e8879

Human memory B cells and plasma cells represent a rich source of antibodies that have been selected in response to human pathogens. In the last decade, different methods have been developed to interrogate the human memory repertoire and isolate monoclonal antibodies. I will discuss how a target‐agnostic approach based on high‐throughput screening of antibodies produced by cultured B cells...

Identification of a novel non-desmoglein autoantigen in Pemphigus Vulgaris

Di Lullo, Giulia ; Calabresi, Valentina ; Mariotti, Feliciana ; Zambruno, Giovanna ; Lanzavecchia, Antonio ; Di Zenzo, Giovanni

In: Frontiers in immunology, 2019, vol. 10, p. 1391

Pemphigus vulgaris (PV) is an autoimmune bullous disease of the skin and mucous membranes characterized by the presence of circulating and tissue-bound autoantibodies against keratinocyte cell surface antigens, specifically desmoglein (Dsg) 1 and 3. The pathogenic role of anti-Dsg antibodies is well-established, while the mechanism of blister formation is only partly defined. We have applied...

The N276 glycosylation site is required for HIV-1 neutralization by the CD4 binding site specific HJ16 monoclonal antibody

Balla-Jhagjhoorsingh, Sunita S. ; Corti, Davide ; Heyndrickx, Leo ; Willems, Elisabeth ; Vereecken, Katleen ; Davis, David ; Vanham, Guido

In: Plos one, 2013, vol. 8, no. 7, p. e68863

Immunogen design for HIV-1 vaccines could be based on epitope identification of naturally occurring neutralizing antibodies in infected patients. A tier 2 neutralizing monoclonal antibody (mAb), HJ16 recognizes a new epitope in the CD4 binding site (CD4bs) region that only partially overlaps with the b12 epitope. We aimed to identify the critical binding site by resistance induction in a...

Characterization of neutralizing profiles in HIV-1 infected patients from whom the HJ16, HGN194 and HK20 mAbs were obtained

Balla-Jhagjhoorsingh, Sunita S. ; Willems, Betty ; Heyndrickx, Liesbeth ; Heyndrickx, Leo ; Vereecken, Katleen ; Janssens, Wouter ; Seaman, Michael S. ; Corti, Davide ; Lanzavecchia, Antonio ; Davis, David ; Vanham, Guido

In: Plos one, 2011, vol. 6, no. 10, p. e25488

Several new human monoclonal antibodies (mAbs) with a neutralizing potential across different subtypes have recently been described. Three mAbs, HJ16, HGN194 and HK20, were obtained from patients within the HIV-1 cohort of the Institute of Tropical Medicine (ITM). Our aim was to generate immunization antibodies equivalent to those seen in plasma. Here, we describe the selection and...

Chronic delivery of antibody fragments using immunoisolated cell implants as a passive vaccination tool

Belaunzaran, Osiris Marroquin ; Cordero, Maria Isabel ; Setola, Veronica ; Bianchi, Siro ; Galli, Carmela ; Bouche, Nicolas ; Mlynarik, Vladimir ; Gruetter, Rolf ; Sandi, Carmen ; Bensadoun, Jean-Charles ; Molinari, Maurizio ; Aebischer, Patrick

In: Plos one, 2011, vol. 6, no. 4, p. e18268

Background: Monoclonal antibodies and antibody fragments are powerful biotherapeutics for various debilitating diseases. However, high production costs, functional limitations such as inadequate pharmacokinetics and tissue accessibility are the current principal disadvantages for broadening their use in clinic. Methodology and Principal Findings: We report a novel method for the long-term ...
