Heterologous booster vaccination enhances antibody responses to SARS-CoV-2 by improving Tfh function and increasing B-cell clonotype SHM frequency

open access: yesFrontiers in Immunology
Heterologous prime-boost has broken the protective immune response bottleneck of the COVID-19 vaccines. however, the underlying mechanisms have not been fully elucidated.

Antibody persistence and safety after heterologous boosting with orally aerosolised Ad5-nCoV in individuals primed with two-dose CoronaVac previously: 12-month analyses of a randomized controlled trial

open access: yesEmerging Microbes and Infections, 2023
Antibody persistence and safety up to 12 months of heterologous orally administered adenovirus type-5 vector-based COVID-19 vaccine (Ad5-nCoV) in individuals who were primed with two-dose inactivated SARS-CoV-2 vaccine (CoronaVac) previously, has not ...

Mesenchymal Stem Cell‐Inspired Microneedle Platform for NIR‐responsive Immunomodulation and Accelerated Chronic Wound Healing

open access: yesAdvanced Materials, EarlyView.
The research demonstrates a Mesenchymal Stem Cell‐inspired microneedle platform (MSCi@MN) that addresses chronic diabetic wounds by combining MSC‐derived extracellular nanovesicles (NV)–DNA conjugates in microneedle tips with photothermal MXene in the patch layer.

DNA Vaccines Encoding Antigen Targeted to MHC Class II Induce Influenza-Specific CD8+ T Cell Responses, Enabling Faster Resolution of Influenza Disease [PDF]

open access: yes, 2016
Current influenza vaccines are effective but imperfect, failing to cover against emerging strains of virus and requiring seasonal administration to protect against new strains. A key step to improving influenza vaccines is to improve our understanding of

A Microfluidic Multiplex Sorter for Strain Development

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A new multiplex method for high‐throughput screening of yeast strains based on glucoamylase production is presented. Droplets containing single mutant yeast cells are incubated for enzyme production. A sorting platform divides mutants by their high‐ and mid‐activity levels.

A heterologous expression system for bovine lens transmembrane main intrinsic protein (MIP) in Nicotiana tabacum plants [PDF]

open access: yes, 1999
We have developed a heterologous expression system for transmembrane lens main intrinsic protein (MIP) in Nicotiana tabacum plant tissue. A native bovine MIP26 amplicon was subcloned into an expression cassette under the control of a constitutive ...

Cattle develop neutralizing antibodies to rotavirus serotypes which could not be isolated from faeces of symptomatic calves [PDF]

open access: yes, 1991
Neutralizing antibodies against 10 serotypes of rotavirus were measured in sera from different age groups of German cattle. Only five of 143 sera did not neutralize heterologous serotypes.

Flavin Biosynthesis Enhances Extracellular Electron Transfer in Bioengineered Escherichia coli

open access: yesAdvanced Science, EarlyView.
Microbial electronics are promising for energy, sensing, environmental, and synthesis applications. E. coli are engineered with extracellular electron transfer (EET) pathways from a microbe that naturally produces current to enable bioelectronics based on E. coli.

DR-bearing T lymphocytes in thoracic duct lymph [PDF]

open access: yes, 1981
T cells having DR antigens were shown to be present in high numbers in the thoracic duct lymph of patients undergoing long-term drainage. As drainage progresses the proportion of T DR cells in the lymph increases to levels as high as 70% at 6 weeks ...
