Towards a Conceptual Framework for Innate Immunity [PDF]

Proceedings of the 4th International Conference on Artificial Immune Systems (ICARIS 2005), Lecture Notes in Computer Science 3627, Banff, Canada, p 112-125, 2010
Innate immunity now occupies a central role in immunology. However, artificial immune system models have largely been inspired by adaptive not innate immunity. This paper reviews the biological principles and properties of innate immunity and, adopting a conceptual framework, asks how these can be incorporated into artificial models.

On the degrees of constructively immune sets [PDF]

arXiv, 2021
Xiang Li (1983) introduced what are now called constructively immune sets as an effective version of immunity. Such have been studied in relation to randomness and minimal indices, and we add another application area: numberings of the rationals. We also investigate the Turing degrees of constructively immune sets and the closely related $\Sigma^0_1 ...

Antigen‐Targeting Inserted Nanomicelles Guide Pre‐Existing Immunity to Kill Head and Neck Cancer

Advanced Science, EarlyView.
This study introduces a tumor‐targeted nanomicelle platform (preS1‐pHLIP) that exploits pre‐existing antiviral immunity to combat heterogeneous cancers. By delivering viral antigens to label tumors as virus‐like targets, the nanomicelles activate antiviral B and T cells, triggering in situ tumor lysis.

Determinants of parents’ intention to vaccinate their children aged 12–17 years against COVID-19 in North Kivu (Democratic Republic of Congo)

Human Vaccines & Immunotherapeutics, 2023
Parents are facing tremendous stress in relation to the COVID-19 pandemic and the effectiveness of the COVID-19 vaccination program for children. We aimed to investigate parents’ willingness to vaccinate their children against COVID-19 in North Kivu ...

Epidemic spreading with immunization rate on complex networks [PDF]

arXiv, 2011
We investigate the spread of diseases, computer viruses or information on complex networks and also immunization strategies to prevent or control the spread. When an entire population cannot be immunized and the effect of immunization is not perfect, we need the targeted immunization with immunization rate.

Dynamics of an SIRWS model with waning of immunity and varying immune boosting period [PDF]

arXiv, 2022
SIRS models capture transmission dynamics of infectious diseases for which immunity is not lifelong. Extending these models by a W compartment for individuals with waning immunity, the boosting of the immune system upon repeated exposure may be incorporated. Previous analyses assumed identical waning rates from R to W and from W to S.

NETs‐CD44‐IL‐17A Feedback Loop Drives Th17‐Mediated Inflammation in Behçet's Uveitis

Advanced Science, EarlyView.
In experimental autoimmune uveitis (EAU), neutrophils interact with T helper 17 (Th17) cells through neutrophil extracellular traps (NETs) to exert a pro‐inflammatory effect. In vitro and in vivo experiments identify that NETs promote IL‐17A secretion in Th17 cells via CD44, and increasing IL‐17A further induces more NETs formation.

Reduction patterns of Japanese encephalitis incidence following vaccine introduction into long-term expanded program on immunization in Yunnan Province, China

Infectious Diseases of Poverty, 2019
Background Japanese encephalitis (JE) is a leading cause of childhood viral encephalitis both at global level and in China. Vaccination is recommended as a key strategy to control JE.

Implementing the communication for development strategy to improve knowledge and coverage of measles vaccination in western Chinese immunization programs: a before-and-after evaluation

Infectious Diseases of Poverty, 2017
Background Communication for Development (C4D) is a strategy promoted by the United Nations Children’s Fund to foster positive and measurable changes at the individual, family, community, social, and policy levels of society.

Two novel immunization strategies for epidemic control in directed scale-free networks with nonlinear infectivity [PDF]

arXiv, 2018
In this paper, we propose two novel immunization strategies, i.e., combined immunization and duplex immunization, for SIS model in directed scale-free networks, and obtain the epidemic thresholds for them with linear and nonlinear infectivities. With the suggested two new strategies, the epidemic thresholds after immunization are greatly increased. For
