Detection of Antibodies to Protective Antigen of Bacillus anthracis Using Indirect Hemagglutination Test and Enzime-Linked Immunosorbent Assay

Проблемы особо опасных инфекций, 2010
Protective antigen, isolated by gel chromatography with the help of sephacril S-300 from the cultural filtrate of B. anthracis strain STI, was used to detect antibodies. Sensitivity of IHA and ELISA with hyperimmune serum to PA corresponded to the titers

The Comparison of Sensitivity and Specificity of ELISA-based Microneutralization Test with Hemagglutination Inhibition Test to Evaluate Neutralizing Antibody against Influenza Virus (H1N1)

Iranian Journal of Public Health, 2017
Background: The most common serological assay to measure anti-influenza antibodies is hemagglutination inhibition (HI) assay. Recently, neutralizing antibodies against influenza virus infection or vaccination can also be detected using ...

Bone Marrow Pathology in Cold Agglutinin‐Mediated Autoimmune Hemolytic Anemia: A Study of 56 Cases

European Journal of Haematology, Volume 117, Issue 2, Page 384-395, August 2026.
ABSTRACT Cold agglutinin disease (CAD) is a rare form of autoimmune hemolytic anemia (AIHA). CAD occurs in the context of a small clonal B‐cell lymphoproliferation restricted to blood and/or bone marrow (BM), without overt or extramedullary lymphoma. The WHO‐HAEM5 introduced a description of the CAD‐associated lymphoproliferative disorder (CAD‐LPD) in ...

A Modified Novel Validated High-Throughput Hemagglutinin Inhibition Assay Using Recombinant Virus-like Particles and Human Red Blood Cells for the Objective Evaluation of Recombinant Hemagglutinin Nanoparticle Seasonal Influenza Vaccine

Microorganisms
Currently available seasonal influenza vaccines confer variable protection due to antigenic changes resulting from the accumulation of diverse mutations. The analysis of new seasonal influenza vaccines is challenging in part due to the limitations of the

H3N2 influenza viruses in humans: Viral mechanisms, evolution, and evaluation

Human Vaccines & Immunotherapeutics, 2018
Annual seasonal influenza vaccines are composed of two influenza A strains representing the H1N1 and H3N2 subtypes, and two influenza B strains representing the Victoria and Yamagata lineages.

Multi‐Omics Comes of Age: Immune Profiling of Human Aging

Immunology &Cell Biology, Volume 104, Issue 7, Page 729-731, August 2026.
A recent study by Gong et al. maps peripheral immune aging using multi‐omic profiling and longitudinal influenza vaccination across adults aged 25–90+, revealing midlife (55–65) immune remodeling. Analyses of PBMCs, proteomics, and cell function show early dysregulation before aging, highlighting links to later disease susceptibility before ...

Humoral immunity to seasonal and zoonotic influenza in the population of the Russian Federation in 2021–2025

Журнал микробиологии, эпидемиологии и иммунобиологии
Introduction. Influenza A virus is one of the major global infectious threats. Along with seasonal epidemics, zoonotic influenza viruses (subtypes А(H5Nх), А(H7Nх), А(H9N2)) pose an increased risk, requiring constant monitoring of herd immunity.

The Dual Role of Preexisting Immunity in Influenza: Protective Recall Versus Constraint of Novel Responses

Immunological Reviews, Volume 341, Issue 1, August 2026.
ABSTRACT Preexisting immunity to influenza confers rapid protection against antigenically matched viruses but can also constrain responses to drifted variants. This review asks when and why prior infection or vaccination is protective versus detrimental, and which biological mechanisms—epitope masking by circulating antibody, inhibitory FcγRIIb ...

Counteracting Influenza Virus Evolution Through the Full Spectrum of Broadly Protective Antibodies

Immunological Reviews, Volume 341, Issue 1, August 2026.
ABSTRACT Despite the presence of licensed vaccines and therapeutics, influenza viruses remain a major public health concern, as they cause seasonal respiratory infections and pose a pandemic threat through the emergence of zoonotic strains. Although neutralizing antibodies elicited by seasonal vaccination constitute a primary defense against infection,
