Currently an oral spore vaccine to Clostridium difficile

Additionally, a spore vaccine to C. perfringens infections in

broilers and PRRSV in swine, underlining the

importance of the SAPHIR project.

One of the challenges in developing efficient

vaccines against enteric pathogens is to mount a

good mucosal immune response. To induce antigen-

specific immunity, a vaccine has to pass protective

barriers and to overcome innate defense and

tolerance mechanisms before it can activate the gut-

associated lymphoid tissue (GALT). More specifically,

a vaccine has to reach the epithelial close to the

GALT in an immunogenic form, pass the epithelial

barrier to reach cells which can present the antigen to

lymphocytes of the GALT, and induce an antigen-

specific immune response which can prevent the

pathogen to cause disease.

Sub-plenary talks were mainly dedicated to Toxoplasma (life cycle evolution and transcriptional profiling during mice infections), Eimeria (description of cryptic species, by SAPHIR member Damer Blake) and Cryptosporidium parasites (genomic studies applied to therapeutics).

The Vaccines and therapeutics session was divided in two main pillars: the discovery of new drugs against toxoplasmosis by targeting host metabolic pathways (Silvia Moreno, University of Georgia), and the development of vaccines based on Eimeria-recombinant vectors (Suo Xun, College of Veterinary Medicine, China Agricultural University). This session was focused on the development of control measures against Eimeria parasites of poultry. During one of the sub-plenary sessions, I had the opportunity to present the positive results we have obtained under the SAPHIR project using transgenic Eimeria parasites as vaccines.

The last session of the ICC covered the topic of Host-pathogen interactions, primarily focusing on poultry coccidiosis. Woo H. Kim and Hyun S. Lillehoj (Animal Biosciences and Biotechnology Laboratory, USDA-ARS) discussed several aspects of the host immune response to avian coccidiosis, and SAPHIR member Marie-Hélène Pinard-van der Laan (Institut National de la Recherche Agronomique) described breeding and genetics strategies to improve host resistance to coccidiosis.

Thanks to its excellent organization, participation in the ICC/ASP conference provided a great opportunity to disseminate information on our SAPHIR project with the international scientific community and allowed networking with potential industry partners.

WP9- Translating basic veterinary immunology to innovative vaccines By Artur Summerfield, Gael Auray and Roman Braun - IVI, Switzerland

INTRODUCTION

Infectious diseases are a major cause for animal

suffering and production losses in livestock and

sometimes they also present a serious hazard for

food safety. Combating infectious diseases of

livestock is therefore a top priority. Mass use of

antibiotics, antiparasitic drugs and vaccines have

been employed, but this practice alone was unable to

provide solutions to many of the multifactorial

disease complexes. The increasing thread of

multidrug resistance caused by inappropriate

employment of antibiotics is a serious concern.

Although vaccines are a great success story they are

lacking efficacy against difficult pathogens and

against certain disease complexes caused by multiple

pathogens typically found in the field.

The mammalian immune system has evolved to

control pathogenic infections and in most cases, is

able to perform its tasks with remarkable efficacy.

The immense variety of pathogens has driven the

evolution of a very complex immune system, which

nevertheless follows relatively simple principles. The

immune system needs to recognize invading

BRIDGING THE GAP

Veterinary immunology focuses on the immune system of

the target species of pathogens and is dedicated to

understand the functioning of immunity in pigs, cattle,

small ruminants, chicken and other relevant species. This

research has demonstrated important species-specific

differences in the immune system. In the frame of SAPHIR

we have analysed in detail the biology of antigen presenting

cells, including dendritic cells and B cells in the pig,

presented in more detail below. These cells are central for

the induction of adaptive immune responses and therefore

represent excellent targets for immunostimulation or

immunomodulation to improve vaccines. An important part

of this work was also the identification of ligands which are

particular strong at activating specific cell types. Such

ligands are currently being tested in vaccine formulations of

mammalian immune system. But the amount of new

prophylactic and therapeutics solutions to human

and animal health has been disappointing. While the

murine model is excellent to discover and explain

basic principles of the mammalian immune system,

details in the distribution and functioning of certain

immune cells and immunological receptors and their

ligands can differ. These differences have been driven

by evolution as different species habitat a different

environment with for instance different food and

pathogen exposure. In addition, major anatomical

differences, for example in the skin, the mucosa, and

the gastrointestinal tract, have a strong influence on

the functioning of the immune system. As a

consequence, extrapolations of adjuvant research

performed in the murine model to other species has

often been disappointing.

response of porcine DC subsets to Toll-like receptor (TLR)

ligands, representing a class of PRR, revealed peculiarities

of the porcine immune system. In particular, we found that

pDCs are by far the most important source of TNF-α, IL-

12p40, and of course IFN-α, while cDCs are most efficient in

MHC and costimulatory molecules expression. On one side,

our data demonstrate that extrapolation of data on DC

biology from one species to another has to be done with

care, on the other side it shows how functional details have

differentially evolved in different species. The knowledge

acquired is now employed for the design of new adjuvant

formulations in the frame of SAPHIR.

Considering that TLR triggering of B cells are known to

promote B cell expansion, differentiation of B cells into

attractive to improve animal vaccines. Our study published

in Frontiers in Immunology (10.3389/fimmu.2017.01044)

investigated the response pattern of porcine B cell subsets

to a large collection of TLR ligands and identified ligands

that are particularly efficient at activating B cells. We also

identified differences in the response of various B-cell

subsets in the response to such ligands and describe for the

first time innate-like B subsets representing the mains

source of immunoglobulin M following TLR stimulation.

PORCINE DENDRITIC CELL SUBSET AND

THEIR RESPONSES TO PAMPS

Dendritic cells (DCs) represent a family of

professional antigen presenting cells which are not

only essential for the induction of adaptive immune

responses but also provide an important link between

innate and adaptive immune response, and shape the

immune response depending on the innate signals

received and the exposed tissue microenvironment.

Using a large panel of antibodies in multicolor flow

cytometry, cell sorting and RNA sequencing, our

work published in The Journal of Immunology

(10.4049/jimmunol.1600672) has identified and

characterized in detail porcine plasmacytoid DCs

(pDCs) and conventional DCs (cDCs), the latter being

further divided into a cDC1 subset and a cDC2 subset.

While pDCs are particularly important for anti-viral

responses through production of high amounts of

type I interferons (especially IFN-α), cDCs are most

efficient at presenting antigen and activating naïve T

cells. cDC1 are specialized in stimulating CD8 T cells,

whereas cDC2 have been shown to be efficient at

promoting Th17 as well as Th2 immune responses

(Figure 2).

Despite cross-species conserved subset-specific

transcripts, porcine DC differed from the species

WP16- How to prevent viremia rebound in virus infections? Evidence from a data-driven mathematical model for PRRS

By Andrea Doeschl-Wilson , Natacha Go and Suzanne Touzeau

Vaccines can drastically alter the environment in

which pathogens live. Indeed, the goal of vaccination

is not only to protect individuals from disease, but to

decrease the risk and severity of disease outbreaks in

populations, and ultimately to eradicate the disease.

For the porcine reproductive respiratory syndrome

(PRRS), one of the most devastating pig diseases in

the world and endemic in most European countries,

vaccination has so far proven ineffective in

controlling the disease. Indeed, the fast evolving,

highly genetically diverse PRRS virus poses a real

challenge for developing fully protective vaccines

with long-term effectiveness.

Figure 1: Functional diagram of the model representing the within-host immune response to PRRSv infection.

Binding of PRRS viral particles (V) and naive target cells (APC) either result in mature and non-infected cells (APCm) that phagocyte viral particles, or in mature and infected cells (APCi) that allow viral replication and excretion of new viral particles. Viral particles are neutralised by antibodies (Ig); infected cells are cytolised by natural killers (NK) and cytotoxic lymphocytes (CD8+). Mature target cells (ACPm and ACPi) present the viral antigen to naive adaptive effectors (CD4+) which activate the CD8+ and B lymphocytes (B). B cells synthesise antibodies. Cytokines are synthesised by various effectors ( ACPm, ACPi, NK, CD4+, CD8+) and regulate most of the immune mechanisms (phagocytosis, infection, excretion, antigen presentation, cytolysis). Regulations are either activation, amplification or inhibitions.

profiles but also offers, for the first time, insight into

potential causative immune mechanisms for generating

rebound. In particular, contrary to current hypotheses

emerging from genetic analyses, this model reveals that

viremia rebound can occur as a result of between-host

differences in the immune competence alone, without the

commonly hypothesized emergence of viral escape

mutants.

Amongst the identified candidate immune mechanisms,

the data-informed model revealed that rebound is

promoted by high target cell apoptosis, high cell infection

and low cytolysis of infected cells by cytotoxic lymphocytes,

while increasing virus neutralisation efficiently prevents

rebound. The model results suggest that vaccines or

genetic selection promoting strong neutralising and

cytolytic responses, ideally associated with low apoptotic

activity and cell permissiveness, would prevent rebound.

Cytotoxic lymphocytes and neutralising antibodies are

usual targets for vaccine development. However, given the

strain-dependent. In particular, virus load rebound

following a steady phase of viral decline (see Figure 2)

is a common and highly undesirable phenomenon for

PRRSv and other viral infections across a range of

species. These rebounders not only suffer prolonged

infection themselves, but are also likely to maintain

the disease in the herd for longer. What causes some

individuals to experience viremia rebound while

others manage to steadily clear the virus?

To determine whether rebound can be caused by

differences in the immune response alone,

researchers from INRA, Inria, France and The Roslin

Institute, UK created a mathematical model of PRRS

within host infection dynamics (see Figure 1) and

fitted it to a dataset from a large scale experiment

(see Figure 2), in which thousands of genetically

diverse pigs were challenged with a virulent PRRS

virus strain (courtesy of the PRRS Host Genetics

Consortium). This mechanistic infection model, fitted

to the experimental data, not only successfully

reproduced the observed wide range of viremia

high diversity of circulating PRRSv strains, cross-

protection remains a major challenge for PRRSv

vaccination. Consequently, alternative solutions that

target non-specific immunity, in particular those

leading to lower target cell permissiveness and/or

reduced apoptotic activities are particularly relevant.

Non-specific immunity can originate from host

intrinsic, genetically driven, innate immune

responses or from alternatively trained immunity.

This non-specific alternatively trained immunity

could result from attenuated vaccines against other

pathogens, as shown in infants, or could be explicitly

elicited by immunostimulants such as those indicated

by the model (such as TNFα) or others yet to be

defined.

The findings of this theoretical study have profound

consequences for the development of successful

PRRS intervention strategies, as they would imply

that rebound and thus possible prolonged virus

transmission in a pig herd can be prevented by

altering the immune response through vaccines or

other pharmaceuticals. The identified immune

mechanisms for preventing rebound could also help

to identify pig genes associated with prolonged virus

transmission.
