The inflammasome adaptor protein ASC promotes amyloid deposition in cryopyrin-associated periodic syndromes.

In this Correspondence, P. Pelegrin and colleagues found that the deposition of amyloid in tissues in Cryopyrin-Associated Periodic Syndrome were promoted by the extracellular presence of the inflammasome adaptor protein ASC, opening exciting new directions in clinical practice to obtain a novel therapy towards secondary amyloidosis in inflammasomopathies.

Sumo-regulatory SENP2 controls the homeostatic squamous mitosis-differentiation checkpoint.

Squamous or epidermoid cancer arises in stratified epithelia but also is frequent in the non-epidermoid epithelium of the lung by unclear mechanisms. A poorly studied mitotic checkpoint drives epithelial cells bearing irreparable genetic damage into epidermoid differentiation. We performed an RNA-sequencing gene search to target unknown regulators of this response and selected the SUMO regulatory protein SENP2.

Lung transplantation for emphysema: only emphysema or something else?

Background: Some studies have reviewed lung explants histology to determine the frequency of pretransplant non-identified neoplasms or explore its diagnostic correlation with a previous diagnosis of interstitial lung disease (ILD). This study aims to review the histopathology of explants from patients who underwent lung transplantation (LT).

Methods: A retrospective, single-center study that included patients who underwent LT for emphysema between 01 January 2011 and 31 October 2021.

Usefulness of COL11A1 as a Prognostic Marker of Tumor Infiltration.

Background: Determining the infiltration of carcinomas is essential for the proper follow-up and treatment of cancer patients. However, it continues to be a diagnostic challenge for pathologists in multiple types of tumors. In previous studies (carried out in surgical specimens), the protein COL11A1 has been postulated as an infiltration marker mainly expressed in the extracellular matrix (ECM).
