Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Fecal virome transplantation attenuates arthritis in mice by remodeling gut ecology, systemic tryptophan metabolism, and innate immune responses

open access: yesnpj Biofilms and Microbiomes
Rheumatoid arthritis (RA) is an autoimmune disorder characterized by chronic joint inflammation and systemic immune dysregulation. Emerging evidence suggests that the gut microbiome plays an important role in immune modulation in RA, yet the role of the ...

Degradation of cellular mir-27 by a novel, highly abundant viral transcript is important for efficient virus replication in vivo. [PDF]

open access: yes, 2012
Cytomegaloviruses express large amounts of viral miRNAs during lytic infection, yet, they only modestly alter the cellular miRNA profile. The most prominent alteration upon lytic murine cytomegalovirus (MCMV) infection is the rapid degradation of the ...

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

open access: yesMolecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Vaccination reduces the viral load and the risk of transmission of Jembrana disease virus in Bali cattle

open access: yes, 2009
The efficacy of a tissue-derived vaccine, which is currently used in Indonesia to control the spread of Jembrana disease in Bali cattle, was determined by quantifying the viral load in plasma following experimental infection with Jembrana disease virus ...

Induction of Noxa-mediated apoptosis by modified vaccinia virus Ankara depends on viral recognition by cytosolic helicases, leading to IRF-3/IFN-β-dependent induction of pro-apoptotic Noxa. [PDF]

open access: yes, 2011
Viral infection is a stimulus for apoptosis, and in order to sustain viral replication many viruses are known to carry genes encoding apoptosis inhibitors. F1L, encoded by the orthopoxvirus modified vaccinia virus Ankara (MVA) has a Bcl-2-like structure.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

IFNL4-rs12979860 CC genotype predisposes to accelerated terminal exhaustion and senescence in HIV/HCV-chronic infection

open access: yesJournal of Translational Medicine
Purpose rs12979860 polymorphism of the lambda 4 interferon (IFNL4) gene has been related with Hepatitis C Virus (HCV) spontaneous clearance (CC genotype favourable versus CT/TT). The implications of this polymorphism over chronic-HCV disease are unknown,

Persistent Innate Immune Stimulation Results in IRF3-Mediated but Caspase-Independent Cytostasis

open access: yesViruses, 2020
Persistent virus infection continuously produces non-self nucleic acids that activate cell-intrinsic immune responses. However, the antiviral defense evolved as a transient, acute phase response and the effects of persistently ongoing stimulation onto ...

A gammaherpesvirus complement regulatory protein promotes initiation of infection by activation of protein kinase Akt/PKB. [PDF]

open access: yes, 2010
Viruses have evolved to evade the host's complement system. The open reading frames 4 (ORF4) of gammaherpesviruses encode homologs of regulators of complement activation (RCA) proteins, which inhibit complement activation at the level of C3 and C4 ...
