An MVA vector expressing HIV-1 envelope under the control of a potent vaccinia virus promoter as a promising strategy in HIV/AIDS vaccine design

Pérez, Patricia ; Marín, María Q. ; Lázaro-Frías, Adrián ; Sorzano, Carlos Óscar S. ; Di Pilato, Mauro ; Gómez, Carmen E. ; Esteban, Mariano ; García-Arriaza, Juan

In: Vaccines, 2019, vol. 7, no. 4, p. 208

Highly attenuated poxviral vectors, such as modified vaccinia virus ankara (MVA), are promising vaccine candidates against several infectious diseases. One of the approaches developed to enhance the immunogenicity of poxvirus vectors is increasing the promoter strength and accelerating during infection production levels of heterologous antigens. Here, we have generated and characterized the ...

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...

Macrophage death following influenza vaccination initiates the inflammatory response that promotes dendritic cell function in the draining lymph node

Chatziandreou, Nikolaos ; Farsakoglu, Yagmur ; Palomino-Segura, Miguel ; D’Antuono, Rocco ; Pizzagalli, Diego Ulisse ; Sallusto, Federica ; Lukacs-Kornek, Veronika ; Uguccioni, Mariagrazia ; Corti, Davide ; Turley, Shannon J. ; Lanzavecchia, Antonio ; Carroll, Michael C. ; Gonzalez, Santiago F.

In: Cell reports, 2017, vol. 18, no. 10, p. 2427-2440

The mechanism by which inflammation influences the adaptive response to vaccines is not fully understood. Here, we examine the role of lymph node macrophages (LNMs) in the induction of the cytokine storm triggered by inactivated influenza virus vaccine. Following vaccination, LNMs undergo inflammasome-independent necrosis-like death that is reliant on MyD88 and Toll-like receptor 7 (TLR7)...

Initiated by CREB: resolving gene regulatory programs in learning and memory: switch in cofactors and transcription regulators between memory consolidation and maintenance network

Kaldun, Jenifer C. ; Sprecher, Simon G.

In: BioEssays, 2019, vol. 41, no. 8, p. 1900045

Consolidation of long‐term memory is a highly and precisely regulated multistep process. The transcription regulator cAMP response element‐binding protein (CREB) plays a key role in initiating memory consolidation. With time processing, first the cofactors are changed and, secondly, CREB gets dispensable. This ultimately changes the expressed gene program to genes required to maintain the...

Antigen-specific Th17 cells are primed by distinct and complementary dendritic cell subsets in oropharyngeal candidiasis

Trautwein-Weidner, Kerstin ; Gladiator, André ; Kirchner, Florian R. ; Becattini, Simone ; Rülicke, Thomas ; Sallusto, Federica ; LeibundGut-Landmann, Salomé

In: PLoS pathogens, 2015, vol. 11, no. 10, p. e1005164

Candida spp. can cause severe and chronic mucocutaneous and systemic infections in immunocompromised individuals. Protection from mucocutaneous candidiasis depends on T helper cells, in particular those secreting IL-17. The events regulating T cell activation and differentiation toward effector fates in response to fungal invasion in different tissues are poorly understood. Here we generated...

Memory T cells in latent mycobacterium tuberculosis infection are directed against three antigenic islands and largely contained in a CXCR3+CCR6+ Th1 subset

Lindestam Arlehamn, Cecilia S. ; Gerasimova, Anna ; Mele, Federico ; Henderson, Ryan ; Swann, Justine ; Greenbaum, Jason A. ; Kim, Yohan ; Sidney, John ; James, Eddie A. ; Taplitz, Randy ; McKinney, Denise M. ; Kwok, William W. ; Grey, Howard ; Sallusto, Federica ; Peters, Bjoern ; Sette, Alessandro

An understanding of the immunological footprint of Mycobacterium tuberculosis (MTB) CD4 T cell recognition is still incomplete. Here we report that human Th1 cells specific for MTB are largely contained in a CXCR3+CCR6+ memory subset and highly focused on three broadly immunodominant antigenic islands, all related to bacterial secretion systems. Our results refute the notion that secreted...

Systems analysis of MVA-C induced immune response reveals its significance as a vaccine candidate against HIV/AIDS of clade C

Gómez, Carmen Elena ; Perdiguero, Beatriz ; Jiménez, Victoria ; Filali-Mouhim, Abdelali ; Ghneim, Khader ; Haddad, Elias K. ; Quakkerlaar, Esther D. ; Delaloye, Julie ; Harari, Alexandre ; Roger, Thierry ; Dunhen, Thomas ; Sékaly, Rafick P. ; Melief, Cornelis J.

Based on the partial efficacy of the HIV/AIDS Thai trial (RV144) with a canarypox vector prime and protein boost, attenuated poxvirus recombinants expressing HIV-1 antigens are increasingly sought as vaccine candidates against HIV/AIDS. Here we describe using systems analysis the biological and immunological characteristics of the attenuated vaccinia virus Ankara strain expressing the HIV-1...

Improved innate and adaptive immunostimulation by genetically modified HIV-1 protein expressing NYVAC vectors

Quakkelaar, Esther D. ; Redeker, Anke ; Haddad, Elias K. ; Harari, Alexandre ; McCaughey, Stella Mayo ; Duhen, Thomas ; Filali-Mouhim, Abdelali ; Goulet, Jean-Philippe ; Loof, Nikki M. ; Ossendorp, Ferry ; Perdiguero, Beatriz ; Heinen, Paul ; Gomez, Carmen E. ; Kibler, Karen V. ; Koelle, David M. ; Sékaly, Rafick P. ; Sallusto, Federica ; Lanzavecchia, Antonio ; Pantaleo, Giuseppe ; Esteban, Mariano ; Tartaglia, Jim ; Jacobs, Bertram L. ; Melief, Cornelis J.

Attenuated poxviruses are safe and capable of expressing foreign antigens. Poxviruses are applied in veterinary vaccination and explored as candidate vaccines for humans. However, poxviruses express multiple genes encoding proteins that interfere with components of the innate and adaptive immune response. This manuscript describes two strategies aimed to improve the immunogenicity of the...
