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.

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...

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...
