Background: Platelets (PLTs) from healthy donors (HD) modulate T lymphocyte respons-es but PLTs rheumatoid arthritis (RA) patients contribute to persistent systemic in-flammation. This suggests that RA and HD have different immuno-modulatory effects. Methods: Using cell culture, flow cytometry, proteomics, ELISA, we compared their effects on activation cytokine pro-duction. Results: suppressed proliferation IFNγ TNF production, while exhibited reduced suppressive capacity. In the presence of...

Immune checkpoint inhibitors (ICI) have the potential to trigger unpredictable immune-related adverse events (irAEs), which can be severe. The underlying mechanisms of these are not fully understood. As PD-L1 is upregulated by IFN, heightened immune activation resulting from PD-1/PD-L1 inhibition may enhance IFN response, triggering expression IFN-inducible genes and contributing irAE development its severity. In this study, we investigated interplay between irAEs chemokines cytokines in 134...

Diagnosis of interstitial lung diseases (ILD) is difficult to perform. Extracellular vesicles (EVs) facilitate cell-to-cell communication, and they are released by a variety cells. Our goal aimed investigate EV markers in bronchoalveolar lavage (BAL) from idiopathic pulmonary fibrosis (IPF), sarcoidosis hypersensitivity pneumonitis (HP) cohorts.
