Antibody-mediated immune surveillance as an organizing axis of gut microbiota structure

Abstract Background The symbiotic interplay between the immune system and the endogenous microbiome is essential for maintaining homeostasis. However, most microbiome research focuses primarily on associations between disease and microbial composition, often overlooking host–micr...

Targeting the Complement C1 Proteases Using Camelid-Derived Single Domain Antibodies: Production, Characterization and Possible Application for Tissue/Fluid Analysis

Background. The complement C1r and C1s proteases initiate the classical complement pathway within the C1 complex, but emerging evidence points to additional roles in tissues, including cell-intrinsic functions linked to cancer and connective tissue disorders. Few tools are availa...

An N-terminal CDC42 T43I variant reveals the mechanism of pyrin inflammasome activation

Heterozygous carboxyl-terminal variants in the RHO guanosine triphosphatase (GTPase) CDC42 are known to cause severe autoinflammatory syndromes. Here, we identified a heterozygous amino-terminal p.T43I (Thr 43 →Ile) CDC42 variant in patients with autoinflammation and uncovered a...

Non-invasive multiparametric characterization of essential thrombocythemia, premyelofibrosis, and overt myelofibrosis

Among myeloproliferative neoplasms (MPN), prefibrotic myelofibrosis (preMF) was defined as a distinct entity from essential thrombocythemia (ET) and primary overt myelofibrosis (PMF) since the 2016 revision of the World Health Organization (WHO) classification, while precise char...
