A large number of prevalent lung diseases is associated with tissue inflammation. Clinically, corticosteroid therapies are applied systemically or via inhalation for the treatment of lung inflammation, and a number of novel therapies are being developed that require preclinical testing. In alveoli, macrophages and dendritic cells play a key role in initiating and diminishing pro-inflammatory...

Are integrins still practicable targets for anti-cancer therapy?

Alday-Parejo, Begoña ; Stupp, Roger ; Rüegg, Curzio

In: Cancers, 2019, vol. 11, no. 7, p. 978

Correlative clinical evidence and experimental observations indicate that integrin adhesion receptors, in particular those of the αV family, are relevant to cancer cell features, including proliferation, survival, migration, invasion, and metastasis. In addition, integrins promote events in the tumor microenvironment that are critical for tumor progression and metastasis, including tumor...

Redox-mediated mechanisms fuel monocyte responses to CXCL12/HMGB1 in active rheumatoid arthritis

Cecchinato, Valentina ; D'Agostino, Gianluca ; Raeli, Lorenzo ; Nerviani, Alessandra ; Schiraldi, Milena ; Danelon, Gabriela ; Manzo, Antonio ; Thelen, Marcus ; Ciurea, Adrian ; Bianchi, Marco E. ; Rubartelli, Anna ; Pitzalis, Costantino ; Uguccioni, Mariagrazia

Chemokine synergy-inducing molecules are emerging as regulating factors in cell migration. The alarmin HMGB1, in its reduced form, can complex with CXCL12 enhancing its activity on monocytes via the chemokine receptor CXCR4, while the form containing a disulfide bond, by binding to TLR2 or TLR4, initiates a cascade of events leading to production of cytokines and chemokines. So far, the...
