Since their discovery, Innate Lymphoid Cells (ILC) have emerged as important effector cells, serving multiple roles in maintaining tissue homeostasis and responding to tissue insults. As such, dysregulations of their function and distribution have been observed in a variety of immune-mediated diseases, suggesting a specific role for ILC in the...

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous family of immune cells including granulocytic (CD14neg/CD15+/HLA-DRneg) and monocytic subtypes (CD14+/CD15neg/HLA-DRneg). In the present study, we found a population of monocytes expressing the granulocyte marker CD15 that significantly increased in both peripheral blood (PB) and...

Growing evidence highlights the pivotal role of ROR gamma t-innate lymphoid cells (ILCs) in the establishment of antitumor immune response and in enhancing tumor sensitivity to immunotherapy. Noteworthy, type 3 ILCs (ILC3s) have been recently acknowledged as an important class of antigen-presenting cells (APCs) in the context of...

NK cells play a crucial role in the clearance of human viruses but their activity is significantly impaired in chronic hepatitis B infected patients (CHB). Cooperation with dendritic cells (DCs) is pivotal for obtaining optimal NK cell antiviral function, thus we investigated whether HBV might impact the ability of DCs to sustain NK cell...

Human DCs and ILC3 can engage in a reciprocal cross-talk resulting in a bidirectional cell activation relevant either in the regulation of mucosal immunity or in promoting pathological processes such as inflammatory hyperproliferative skin diseases.

Background: Respiratory viral infections are a leading cause of severe diseases and mortality; therefore, novel treatments effective for their prevention are highly requested. Here, we identified a broad-spectrum antiviral activity of a natural exopolysaccharide, EPS T14, purified from a marine thermotolerant strain of Bacillus licheniformis...

Type 3 innate lymphoid cells (ILC3s) are primarily tissue-resident cells strategically localized at the intestinal barrier that exhibit the fast-acting responsiveness of classic innate immune cells. Populations of these lymphocytes depend on the transcription factor RAR-related orphan receptor and play a key role in maintaining intestinal...

: The recent evolution of immunotherapy has revolutionised the treatment of hepatocellular carcinoma (HCC) and has led to new therapeutic standards. The advances in immunotherapy have been accompanied by the recognition of the role of the gut-liver axis in the progression of HCC but also of the clinical relevance of the gut microbiota, which...

Proinflammatory monocytes play a preponderant role in the development of a cytokine storm causing fatal consequences in coronavirus disease 2019 (COVID-19) patients, highlighting the importance of analyzing in more detail monocyte distribution in these patients. In this study, we identified an atypical monocyte subpopulation expressing CD56...

Polyvalent mechanical bacterial lysate is effective in the prevention of respiratory tract infections, although its mechanism of action is not entirely elucidated. Because epithelial cells constitute the frontline defense against infections, we investigated the molecular mechanisms of innate response exerted by bronchial epithelial cells in the...
