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 ...

Primary case of human pneumonic plague occurring in a Himalayan marmot natural focus area Gansu Province, China

International Journal of Infectious Diseases, 2015
A case of primary pneumonic plague (PPP) caused by Yersinia pestis is reported. This case occurred in the largest plague area in China. The patient died after contact with a dog that had captured an infected marmot. Three of 151 contacts were shown to be

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,

Low population serum microneutralization antibody titer against the predominating influenza A(H3N2) N121K virus during the severe influenza summer peak of Hong Kong in 2017

Emerging Microbes and Infections, 2018
The 2017 Hong Kong influenza A(H3N2) summer season was unexpectedly severe. However, antigenic characterization of the 2017 circulating A(H3N2) viruses using ferret antisera did not show significant antigenic drift.

Molecular characterization of D variants in Brazilian blood donors and their association with RhCE and Duffy phenotypes

Vox Sanguinis, Volume 121, Issue 8, Page 1210-1219, August 2026.
Abstract Background and Objectives Serological classification of RhD‐negative and weak D is often insufficient in admixed populations, where diverse RHD variants have clinical implications. In Brazil's highly admixed population, RhD interpretation and donor–recipient matching are particularly challenging.
