Trained-immunity and cross-reactivity for protection: insights from the coronavirus disease 2019 and monkeypox emergencies for vaccine development

open access: yesExploration of Immunology, 2023
The emergence and re-emergence of pathogens is a public-health concern, which has become more evident after the coronavirus disease 2019 (COVID-19) pandemic and the monkeypox outbreaks in early 2022.

Heterologous autoimmunity and prokaryotic immune defense [PDF]

open access: yes, 2021
Some prokaryotes possess CRISPR-Cas systems that provide adaptive immunity to viruses guided by DNA segments called spacers acquired from invading phage. However, the patchy incidence and limited memory breadth of CRISPR-Cas systems suggest that their fitness benefits are offset by costs.

Controlled functional expression of the bacteriocins pediocin PA-1 and bactofencin A in Escherichia coli [PDF]

open access: yes, 2017
peer-reviewedThe bacteriocins bactofencin A (class IId) and pediocin PA-1 (class IIa) are encoded by operons with a similarly clustered gene organization including a structural peptide, an immunity protein, an ABC transporter and accessory bacteriocin ...

Heterologous effects of vaccination and trained immunity [PDF]

open access: yesClinical Microbiology and Infection, 2019
Vaccines are applied to large populations, but only recently has research into immunologic responses and mechanisms started to increase exponentially. Some live vaccines, such as the tuberculosis vaccine bacillus Calmette-Guérin, protect against other infections nonspecifically by eliciting complex immune responses which are not specific antibody ...

Long-lasting cross-protection against influenza A by neuraminidase and M2e-based immunization strategies [PDF]

open access: yes, 2016
There is mounting evidence that in the absence of neutralizing antibodies cross-reactive T cells provide protection against pandemic influenza viruses. Here, we compared protection and CD8+ T cell responses following challenge with H1N1 2009 pandemic and

Cross-Protective Immunity against Heterologous Streptococcus pneumoniae [PDF]

open access: yesInfection and Immunity, 2012
Chimalapati et al. recently reported that infection with conditionally virulent Streptococcus pneumoniae Δ pab strains (containing a deletion of the gene encoding para -aminobenzoic acid synthetase) induced an effective antibody response to conserved protein antigens of S. pneumoniae ([1][1]).

Development of a novel equine influenza virus live-attenuated vaccine [PDF]

open access: yes, 2018
H3N8 equine influenza virus (EIV) is an important and significant respiratory pathogen of horses. EIV is enzootic in Europe and North America, mainly due to the suboptimal efficacy of current vaccines. We describe, for the first time, the generation of a

Defective interfering virus protects elderly mice from influenza [PDF]

open access: yes, 2011
Background: We have identified and characterised a defective-interfering (DI) influenza A virus particles containing a highly deleted segment 1 RNA that has broad-spectrum antiviral activity.

In-depth analysis of T cell immunity and antibody responses in heterologous prime-boost-boost vaccine regimens against SARS-CoV-2 and Omicron variant

open access: yesFrontiers in Immunology, 2022
With the emergence of novel Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) Variants of Concern (VOCs), vaccination studies that elucidate the efficiency and effectiveness of a vaccination campaign are critical to assess the durability and ...

Pathogenic epitopes, heterologous immunity and vaccine design [PDF]

open access: yesNature Reviews Microbiology, 2007
Substantial research has been directed towards the development of a new generation of vaccines that are based on the inclusion of immunogenic epitopes in recombinant vectors. Here we examine the evidence that under certain conditions immunogenic epitopes can do more harm than good and might therefore be considered pathogenic.
