SPECIFIC HETEROLOGOUS ENHANCEMENT OF IMMUNE RESPONSES [PDF]

The Journal of Experimental Medicine, 1973
The mixing of two histoincompatible human lymphocyte cell lines generated the release of a soluble factor which was capable of nonspecifically enhancing the in vitro immune response of normal mouse spleen cells against sheep erythrocytes. When active supernates were subjected to exclusion chromatography on Sephadex G-150 and BioGel P-150, the active ...

Genetic relatedness of infecting and reinfecting respiratory syncytial virus strains identified in a birth cohort from rural Kenya [PDF]

, 2012
Background: Respiratory syncytial virus (RSV) reinfects individuals repeatedly. The extent to which this is a consequence of RSV antigenic diversity is unclear.

Immunization with an autotransporter protein of Orientia tsutsugamushi provides protective immunity against scrub typhus. [PDF]

PLoS Neglected Tropical Diseases, 2015
BACKGROUND:Scrub typhus is an acute febrile disease caused by Orientia tsutsugamushi infection. Recently, the rapid increase of scrub typhus incidence in several countries within the endemic region has become a serious public health issue.

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

Exploration 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.

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

, 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 autoimmunity and prokaryotic immune defense [PDF]

, 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.

Heterologous Immunity and Persistent Murine Cytomegalovirus Infection [PDF]

Journal of Virology, 2017
ABSTRACT One's history of infections can affect the immune response to unrelated pathogens and influence disease outcome through the process of heterologous immunity. This can occur after acute viral infections, such as infections with lymphocytic choriomeningitis virus (LCMV) and vaccinia virus, where the pathogens are cleared ...

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

, 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

Heterologous effects of vaccination and trained immunity [PDF]

Clinical 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 ...

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

, 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
