Innate immune cells and their contribution to T-cell-based immunotherapy

Ginefra, Pierpaolo ; Lorusso, Girieca ; Vannini, Nicola

In: International Journal of Molecular Sciences, 2020, vol. 21, no. 12, p. 4441

In recent years, immunotherapy has become the most promising therapy for a variety of cancer types. The development of immune checkpoint blockade (ICB) therapies, the adoptive transfer of tumor-specific T cells (adoptive cell therapy (ACT)) or the generation of T cells engineered with chimeric antigen receptors (CAR) have been successfully applied to elicit durable immunological responses in...

Granzyme B attenuates bacterial virulence by targeting secreted factors

López León, Diego ; Matthey, Patricia ; Fellay, Isabelle ; Blanchard, Marianne ; Martinvalet, Denis ; Mantel, Pierre-Yves ; Filgueira, Luis ; Walch, Michael

In: iScience, 2020, vol. 23, no. 3, p. 100932

Pathogenic bacteria secrete virulence factors that interact with the human host to establish infections. The human immune system evolved multiple mechanisms to fight bacterial invaders, including immune proteases that were demonstrated to contribute crucially to antibacterial defense. Here we show that granzyme B degrades multiple secreted virulence mediators from Listeria monocytogenes,...

A novel interaction between the TLR7 and a colchicine derivative revealed through a computational and experimental study

Gentile, Francesco ; Deriu, Marco A. ; Barakat, Khaled ; Danani, Andrea ; Tuszynski, Jack

In: Pharmaceuticals, 2018, vol. 11, no. 1, p. 22

The Toll-Like Receptor 7 (TLR7) is an endosomal membrane receptor involved in the innate immune system response. Its best-known small molecule activators are imidazoquinoline derivatives such as imiquimod (R-837) and resiquimod (R-848). Recently, an interaction between R-837 and the colchicine binding site of tubulin was reported. To investigate the possibility of an interaction between...

Potential of PEGylated toll-like receptor 7 ligands for controlling inflammation and functional changes in mouse models of asthma and silicosis

Teixeira Ferreira, Tatiana Paula ; Lacerda Mariano, Lívia ; Ghilosso-Bortolini, Roberta ; Santos de Arantes, Ana Carolina ; Fernandes, Andrey Junior ; Berni, Michelle ; Cecchinato, Valentina ; Uguccioni, Mariagrazia ; Maj, Roberto ; Barberis, Alcide ; Machado Rodrigues Silva, Patricia ; Martins, Marco Aurélio

In: Frontiers in immunology, 2016, vol. 7, p. 95

Prior investigations show that signaling activation through pattern recognition receptors can directly impact a number of inflammatory lung diseases. While toll-like receptor (TLR) 7 agonists have raised interest for their ability to inhibit allergen-induced pathological changes in experimental asthma conditions, the putative benefit of this treatment is limited by adverse effects. Our aim...

MiR-146a in immunity and disease

Rusca, Nicole ; Monticelli, Silvia

In: Molecular biology international, 2011, vol. 2011, p. 1-7

MicroRNAs (miRNAs) are regulatory molecules able to influence all aspects of the biology of a cell. They have been associated with diseases such as cancer, viral infections, and autoimmune diseases, and in recent years, they also emerged as important regulators of immune responses. MiR-146a in particular is rapidly gaining importance as a modulator of differentiation and function of cells of...
