Ficolins, which are comprised of a collagen-like domain and a fibrinogen-like domain, are a kind of pattern-recognition molecule for pathogens in the innate immunity system. To investigate the molecular mechanism of the discrimination between self and non-self by ficolins, human M-ficolin fibrinogen-like domain (FD1), which contains the ligand-binding site, was overexpressed in Pichia pastoris, purified and crystallized using the vapour-diffusion method at 293 K. The crystals belong to the monoclinic space group P2(1), with unit-cell parameters a = 55.16, b = 117.45, c = 55.19 angstroms, beta = 99.88 degrees, and contain three molecules per asymmetric unit. An X-ray data set was collected to 1.9 angstroms resolution using synchrotron radiation at beamline BL24XU at the SPring-8 facility in Japan.

Background & Aims: ICC is a malignant tumor that originates from the intrahepatic bile ducts with insidious symptoms and a poor prognosis. Early diagnosis methods and therapeutic targets are urgently needed for ICC.
Methods: We utilized a comprehensive set of analytical techniques to elucidate the role and mechanisms of DCDC2 in ICC.

Rheumatoid arthritis (RA) is a common autoimmune disorder characterized by exacerbated joint inflammation. Despite the well-documented accumulation of the serine protease granzyme B (GzmB) in RA patient biospecimens, little is understood pertaining to its role in pathobiology. In the present study, tenascin-C (TNC) - a large, pro-inflammatory extracellular matrix glycoprotein - was identified as a substrate for GzmB in RA.

Non-small cell lung cancer (NSCLC) is characterized by a high incidence rate and poor prognosis worldwide. A deeper insight into the pathogenesis of NSCLC and identification of novel therapeutic targets are essential to improve the prognosis of NSCLC. In this study, we revealed that fibrinogen-like protein 1 (FGL1) promotes proliferation, migration, and invasion of NSCLC cells.

Background: Anti-programmed death-1 (PD-1)/anti-PD-ligand-1 (PD-L1) pathway inhibition is a standard regimen for advanced urothelial carcinoma (UC); however, its limited efficacy has been reflected in reported medium response rates. This study explored the role of next-generation coinhibitory receptors (IRs; lymphocyte activation gene 3 (LAG-3), T-cell immunoglobulin and mucin domain 3 (TIM-3), and T-cell immunoreceptor with Ig and ITIM domains (TIGIT)) and their ligands (LGs) in the response to PD-(L)1 blockade therapy and the oncological outcomes in patients with UC.
Methods: We investigated metastatic UC cases who underwent PD-(L)1 therapy (cohort 1: n=348, cohort 2: n=89, and cohort 4: n=29) or advanced UC cases involving surgery (cohort 3: n=293 and cohort 5: n=90).

Introduction: The N-terminal domain of angiopoietin-like protein 3 (ANGPTL3) inhibits lipoprotein lipase activity. Its C-terminal fibrinogen-like (FBN) domain is a ligand of macrophage integrin αvβ3.
Objectives: ANGPTL3 might home to plaque where it directly regulates macrophage function via integrin αvβ3 for atherosclerosis progression.
