Innovative therapy, monoclonal antibodies, and beyond: Highlights from the eighth annual meeting
The eighth annual conference of “Innovative therapy, monoclonal antibodies, and beyond” was held in Milan on Jan. 26, 2018, and hosted by Fondazione IRCCS–Istituto Nazionale dei Tumori (Fondazione IRCCS INT). The conference was divided into two main scientific sessions, of i) pre-clinical assays and novel biotargets, and ii) clinical translation, as well as a third session of presentations from young investigators, which focused on recent achievements within Fondazione IRCCS INT on immunotherapy and targeted therapies. Presentations in the first session addressed the issue of cancer immunotherapy activity with respect to tumor heterogeneity, with key topics addressing: 1) tumor heterogeneit…
Innovative Therapy, Monoclonal Antibodies and Beyond
IF 6.794; International audience; The seventh Edition of "Innovative Therapy, Monoclonal Antibodies and Beyond" Meeting took place in Milan, Italy, on January 27, 2017. The two sessions of the meeting were focused on: 1) Preclinical assays and novel biotargets; and 2) monoclonal antibodies, cell therapies and targeted molecules. Between these two sessions, a lecture entitled "HLA-antigens modulation and response to immune checkpoint inhibitor immunotherapy" was also presented. Despite the impressive successes in cancer immunotherapy in recent years, the response to immune based interventions occurs only in a minority of patients (∼20%). Several basic and translational mechanisms of resistan…
Ub surprised: viral ovarian tumor domain proteases remove ubiquitin and ISG15 conjugates.
Ubiquitin (Ub) and interferon stimulated gene product 15 (ISG15) reversibly conjugate to proteins via a conserved LRLRGG C-terminal motif, mediating important innate antiviral responses. The ovarian tumor (OTU) domain represents a superfamily of predicted proteases found in eukaryotic, bacterial and viral proteins, some of which have Ub-deconjugating activity. We show that the OTU domain-containing proteases of nairoviruses and arteriviruses hydrolyze Ub and ISG15 from cellular target proteins. This broad activity contrasts with the target specificity of known mammalian OTU domain-containing proteins. The biological significance of this activity of viral OTU domain-containing proteases was …
