Background/Objectives: Calsequestrin (CSQ) is a calcium-binding protein that is highly soluble and can serve as a solubility-enhancing fusion tag in recombinant protein expression. Its unique property of calcium-induced precipitation followed by EDTA...

Background/Objectives: Lichen planus (LP) is a chronic inflammatory disease of autoimmune origin, affecting the skin and mucous membranes. While corticosteroids and immunosuppressants are traditionally used, many cases remain refractory or intolerant...

Background: The accurate evaluation of anti-ABO antibodies is essential for risk stratification in ABO-incompatible (ABOi) transplantation. Historically, hemagglutination-based titration has been the cornerstone of such an assessment; however, differ...

Background: p16 immunohistochemistry (IHC) serves as a surrogate marker for high-risk human papillomavirus (hrHPV) and is widely used in gynecologic pathology. However, few studies have directly compared the staining performance and reproducibility o...

Infertility is a multifactorial condition with a wide range of potential causes, including anatomical, hormonal, genetic, and lifestyle-related factors. Among these, immunological mechanisms have increasingly been recognized as important contributors...

Background: Dupilumab, a monoclonal antibody targeting the interleukin-4 receptor α, is approved for moderate-to-severe atopic dermatitis (AD). However, its safety profile in patients with concomitant hematologic disorders remains unclear, as s...

Background: Bispecific antibodies have emerged as a promising class of therapeutics, enabling simultaneous targeting of two distinct antigens. Single-domain antibodies (sdAbs) comprising camelid variable heavy chains (VHHs) provide a compact and adap...

Background/Objectives: Single-domain immunoglobulins are small protein modules with specific affinities. Among them, the variable domains of heavy chains of heavy-chain-only antibodies (VHH) as the antigen-binding fragment of heavy-chain-only antibod...

Background: Monoclonal antibodies play an important role in therapeutic and analytical applications. For recombinant expression, the coding sequences of the variable regions of the heavy and light chains are required. In addition, cloning antibody se...

Background/Objectives: The complexity of diseases such as cancer and auto-immune disorders drives the need for unique, target-driven therapeutics. A broader arsenal to generate better biologics-based therapeutics is needed to provide more efficient a...

Background/Objectives: Cows produce antibodies with ultralong CDRH3 segments (ulCABs) that contain a disulfide-stabilized knob domain. This domain is connected to the globular core of the antibody by a β-strand stalk. In the crystal structures,...

Background: The concentration of antigen-specific antibodies in serum is usually measured in international units/mL. Therefore, the actual concentration of virus-specific antibodies in sera is unknown. Objectives: The aim of the study was to determin...

Background: When an antigen molecule is exposed to serum, many different kinds of antibodies bind to it. The complexity of these binding events is only poorly characterized by assays that generate a single variable, generally reflecting the fractiona...

Background: Podocalyxin (PODXL) has been identified as a promising therapeutic target and a potential diagnostic biomarker in various tumors. Despite the therapeutic potential of anti-PODXL monoclonal antibodies (mAbs), their further development has...

Background/Objectives: Anti-p200 pemphigoid is a rare and likely underdiagnosed autoimmune blistering disorder. Laminin γ1 and laminin β4 have been implicated as potential target antigens in its pathogenesis. Recently, a novel indirect imm...

Antibody-mediated autoimmune diseases are common, can involve any organ system, and pose a large burden for patients and healthcare systems. Most antibody-mediated diseases are mediated by IgG antibodies. Selective targeting of pathogenic antibodies...

Pompe disease is a rare autosomal-recessive neuromuscular disorder caused by a deficiency of the lysosomal enzyme acid alpha-glucosidase (GAA), leading to the pathological accumulation of glycogen and impaired autophagy. Enzyme replacement therapy (E...

Background/Objectives: Immune-mediated necrotizing myopathy (IMNM) is a severe inflammatory myopathy marked by proximal muscle weakness, elevated creatine kinase (CK), and the presence of anti-HMGCR antibodies. Statin exposure is a recognized trigger...

Background/Objectives: Anti-drug antibody (ADA) formation can impact the safety, pharmacokinetics, and/or efficacy of biotherapeutics, including monoclonal antibodies (mAbs). Current strategies for ADA/immunogenicity risk prediction of mAbs include i...

Background: Mepolizumab is an effective treatment for severe eosinophilic asthma, leading to a depletion of blood eosinophil levels, the clinical relevance of which remains unclear. Objective: The aim of this study was to assess the relationship betw...

Food-borne zoonoses, particularly anisakiosis caused by Anisakis spp., are an increasing public health concern due to the rising consumption of raw fish. Anisakiosis results from the ingestion of third-stage larvae of Anisakidae nematodes, with the g...

Objectives: The durability and breadth of neutralizing antibodies following SARS-CoV-2 mRNA vaccination remain incompletely understood. This study aimed to investigate how longitudinal changes in antibody isotype composition impact neutralization aga...

Immunotherapy has emerged as a transformative approach in gastrointestinal (GI) cancers, addressing historically poor survival rates in advanced-stage disease. Immune checkpoint inhibitors (ICIs) targeting the PD-1/PD-L1 axis demonstrate remarkable e...

Background: Human cytomegalovirus (CMV) is a major pathogen that poses significant risks to immunocompromised individuals and neonates. The tegument protein pp71, encoded by the UL82 gene, plays a pivotal role in initiating viral lytic replication an...

Connective tissue diseases (CTDs) comprise a heterogeneous group of autoimmune conditions characterized by diverse clinical manifestations and autoantibody profiles, posing significant diagnostic challenges. This systematic review and meta-analysis e...

Thyroid eye disease (TED) is a complex autoimmune disorder characterized by orbital inflammation and tissue remodeling. Teprotumumab, a fully human monoclonal antibody targeting insulin-like growth factor-1 receptor (IGF-1R), represents a significant...

Objectives: The present study aimed to evaluate the long-term survival of patients with rheumatoid arthritis (RA) receiving biologic or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) in a real-world setting, and to identify key...

Recombinantly produced monoclonal antibodies (mabs) belong to the fastest growing class of biotherapeutics. In humans, antibodies are classified into five different classes: IgA, IgD, IgE, IgG and IgM. Most of the therapeutic mabs used in the clinic...
