High-grade-B-cell lymphoma (HGBL) with MYC and BCL2 and/or BCL6 rearrangements (double hit [HGBL-DH] or triple hit [HGBL-TH]), or not otherwise specified (HGBL-NOS), are considered to be more aggressive diseases among large B-cell lymphomas (LBCL). CD19-targeting Chimeric Antigen Receptor (CAR) T-cells have changed the prognosis of chemoresistant LBCL. Clinical and pathological data of patients treated for relapsed/refractory LBCL or HGBL in third line or more, all characterized by FISH, were collected from the French DESCAR-T registry.

Autophagy deficiency affects antigen presentation in conventional dendritic cells (DCs) without impacting their survival. However, previous studies did not address epidermal Langerhans cells (LCs).

Additionally, circulating levels of CXCL4, a novel SSc biomarker, correlate with more severe fibrotic manifestations of the disease. Considering the defective efferocytosis of macrophages in SSc and the CXCL4-related M4 macrophage phenotype, we hypothesized that CXCL4 could be involved in the alteration of phagocytic functions of macrophages in SSc, including LC3-associated phagocytosis (LAP), another phagocytic process requiring autophagy proteins and contributing to immune silencing.
