Intraductal Oncocytic Papillary Neoplasm (IOPN): Two Case Reports and Review of the Literature [PDF]
Intraductal oncocytic papillary neoplasms (IOPNs) place at the oncocytic extreme of the intraductal pancreatic neoplasm spectrum and display typical morphological features. Their identification in 1996 by Adsay et al. has been followed by a growing number of cases, paving the way for a deeper understanding of this underestimated entity.

Characterization and Digital Spatial Deconvolution of the Immune Microenvironment of Intraductal Oncocytic Papillary Neoplasms (IOPN) of the Pancreas [PDF]
AbstractIntraductal oncocytic papillary neoplasm (IOPN) of the pancreas is a distinct entity from intraductal papillary mucinous neoplasms (IPMNs) and is considered one of the precursor lesions of pancreatic cancer. Through immunohistochemistry (IHC) and an artificial intelligence (AI)-based approach, this study aims at characterizing its immune ...

OPN promotes pro-inflammatory cytokine expression via ERK/JNK pathway and M1 macrophage polarization in Rosacea [PDF]
Rosacea is a chronic inflammatory dermatosis that involves dysregulation of innate and adaptive immune systems. Osteopontin (OPN) is a phosphorylated glycoprotein produced by a broad range of immune cells such as macrophages, keratinocytes, and T cells ...

Two different isoforms of osteopontin modulate myelination and axonal integrity [PDF]
Abnormal myelination underlies the pathology of white matter diseases such as preterm white matter injury and multiple sclerosis. Osteopontin (OPN) has been suggested to play a role in myelination.

Case Report: Metachronous oncocytic and colloid carcinoma arising from pancreatic intraductal neoplasms over four decades [PDF]
Intraductal papillary mucinous neoplasms (IPMN) are precursors of pancreatic ductal adenocarcinoma (PDAC) and may progress to distinct invasive phenotypes depending on epithelial subtypes. Tubular carcinoma, often arising from pancreatobiliary epithelium,

MRI findings of pancreatic intraductal oncocytic papillary neoplasm: three case reports and review of literature [PDF]
BackgroundPancreatic intraductal oncocytic papillary neoplasms (IOPNs) are uncommon precancerous lesions frequently mistaken for other tumors because of their similar imaging characteristics. The concept of IOPN was first proposed by Adsay et al. in 1996.
