Antibodies to Cryptic Epitopes in Distant Homologues Underpin a Mechanism of Heterologous Immunity between <i>Plasmodium vivax</i> PvDBP and <i>Plasmodium falciparum</i> VAR2CSA. [PDF]

open access: yesmBio, 2019
Many pathogens evolve extensive genetic variation in virulence proteins as a strategy to evade host immunity. This poses a significant challenge for the host to develop broadly neutralizing antibodies.

Subcutaneous BCG vaccination protects against streptococcal pneumonia via regulating innate immune responses in the lung

open access: yesEMBO Molecular Medicine, 2023
Bacillus Calmette‐Guérin (BCG) still remains the only licensed vaccine for TB and has been shown to provide nonspecific protection against unrelated pathogens.

Suppression of adaptive immunity to heterologous antigens during Plasmodium infection through hemozoin-induced failure of dendritic cell function [PDF]

open access: yes, 2005
Background: Dendritic cells (DCs) are central to the initiation and regulation of the adaptive immune response during infection. Modulation of DC function may therefore allow evasion of the immune system by pathogens. Significant depression of the host'

Heterologous infection and vaccination shapes immunity against SARS-CoV-2 variants [PDF]

open access: yes, 2021
The impact of initial severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infecting strain on downstream immunity to heterologous variants of concern (VOC) is unknown.

SPECIFIC HETEROLOGOUS ENHANCEMENT OF IMMUNE RESPONSES [PDF]

open access: yesThe 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 ...

A high force of Plasmodium vivax blood-stage infection drives the rapid acquisition of immunity in Papua New Guinean children [PDF]

open access: yes, 2013
When both parasite species are co-endemic, Plasmodium vivax incidence peaks in younger children compared to P. falciparum. To identify differences in the number of blood stage infections of these species and its potential link to acquisition of immunity,

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

open access: yesPLoS 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.

Heterologous immunity in the absence of variant-specific antibodies after exposure to subpatent infection with blood-stage malaria [PDF]

open access: yes, 2005
We examined immunity induced by subpatent blood-stage malaria (undetectable by microscopy) using the rodent malaria parasite, Plasmodium chabaudi chabaudi, postulating that limited infection may allow expansion of antigen-specific T cells that are ...

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.

Immune complex glomerulonephritis is induced in rats immunized with heterologous myeloperoxidase [PDF]

open access: yesClinical and Experimental Immunology, 1994
SUMMARY Anti-neutrophil cytoplasmic antibodies (ANCA), including anti-myeloperoxidase (MPO) antibodies, are associated with pauci-immune necrotizing small vessel vasculitis or glomerulonephritis, 1n order to substantiate a pathogenic role for ANCA, an animal model of pauci-immune ANCA-induced glomerulonephritis or vasculitis is required.
