Increasing evidence supports a role for small extracellular vesicles (sEV, including exosomes) in Diffuse Large B-cell lymphoma (DLBCL) progression and resistance to treatment. CD20 and PD-L1 are found on DLBCL-derived sEV, but little is known about their patient-level heterogeneity. Moreover, the capacity of PD-L1 sEV to modulate T cells needs to be clarified.

Prohibitin 1 (PHB1) and prohibitin 2 (PHB2) are scaffold proteins that promote mitochondria homeostasis and consequently cell survival, but biological functions of cytoplasmic PHBs remain largely unknown in DLBCL.
Methods: PHB expression was analyzed in 82 DLBCL biopsies and five DLBCL cell lines by immunohistochemistry (IHC) and Western blotting.
Background: Diffuse large B-cell lymphoma (DLBCL) is a fatal malignancy that needs to identify new targets for additional therapeutic options. This study aimed to clarify the clinical and biological significance of endogenous neurotrophin (nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF)) in DLBCL biopsy samples and cell lines.
Methods: We analysed expression of NGF, BDNF, and their receptors (Trk, p75(NTR)) in 51 biopsies and cell lines by immunohistochemistry, immunofluorescence, and western blotting.
Background: To determine whether proapoptotic proteins were associated with clinicopathologic heterogeneity and influenced survival in patients with diffuse large B-cell lymphoma (DLBCL), we evaluated patterns of expression of the BCL-2 family member BAD, PP1alpha (the catalytic subunit of PP1 involved in activation of BAD), and apoptosis-inducing factor (AIF).
Patients And Methods: We retrospectively analyzed 46 patients all treated with standard chemotherapy ([CHOP] cyclophosphamide/doxorubicin/vincristine/prednisone-like); of these, 16 received rituximab. Immunohistochemical analyses were performed from biopsy samples of nodal DLBCL that were performed at initial diagnosis.
