About This PhD and Research Opportunity
The University of Cambridge, through its Department of Pathology, is inviting applications for a four-year PhD studentship investigating how the immune systems of different animal species recognise and respond to viruses that can cross species barriers.
The research project, titled Comparative Innate Immune Sensing of Zoonotic Viruses, will be supervised by Professor Brian Ferguson. It is part of the Department of Pathology's funded doctoral research opportunities, with the successful candidate expected to begin in October 2027.
The project addresses an important question in infectious disease research: why do some viruses cause severe illness when they infect a new animal species, while others produce less severe infections or fail to establish themselves?
Viruses that move between animals and humans are known as zoonotic viruses. Their emergence can lead to outbreaks and, in some cases, serious public health threats. However, the outcome of infection is not determined by the virus alone. The immune system of the infected host also plays a major role in determining whether a virus is detected, controlled or able to spread.
This PhD will investigate differences in the early immune-recognition mechanisms of different host species. By comparing how their cells detect viral material and activate immune responses, the researcher will help identify biological factors that influence cross-species infection, viral adaptation and the emergence of zoonotic diseases.
The studentship is particularly relevant to applicants interested in virology, immunology, molecular biology, infectious diseases, host-pathogen interactions and comparative biology.
Important eligibility restriction: The studentship is funded for applicants who qualify for UK Home-rate tuition fees only. Although the project is based in the UK and may be of interest to international researchers, applicants who are required to pay overseas tuition fees are not eligible under this particular funding arrangement.
1. Understanding the research project
When a virus enters an animal or human body, the immune system must recognise that something foreign is present and activate protective responses.
One of the body's earliest defence mechanisms is the innate immune system. Unlike adaptive immunity, which develops more specialised responses after exposure, innate immunity provides an immediate system of defence against invading pathogens.
A central part of this early defence involves proteins called pattern recognition receptors (PRRs).
These receptors recognise molecular features associated with viruses and other pathogens. Once they detect viral material, they activate signalling pathways that help the infected cell and surrounding tissues respond to the infection.
However, these recognition systems are not necessarily identical across animal species.
A virus that is efficiently detected by the immune system of one species may interact differently with the immune system of another. Differences in receptor structure, signalling strength and immune regulation may influence whether the virus can establish an infection, reproduce, evade immune detection or cause severe disease.
The PhD project will investigate these differences using comparative approaches in molecular virology and immunology.
The findings may improve understanding of why certain viruses can cross species barriers and why the severity of infection can vary between hosts.
2. What the researcher will investigate
The project will examine how differences in pattern recognition receptor signalling influence viral infection and host responses across species.
The main research questions include:
How do different species recognise viral infections?
The researcher will compare the pattern recognition receptor pathways involved in detecting viral material in different host species. This will help identify which immune-recognition mechanisms are conserved across species and which show important differences.
How do immune-signalling pathways influence infection outcomes?
After a virus is detected, immune cells activate signalling pathways that regulate antiviral responses. The project will examine how differences in the strength and regulation of these signals affect the outcome of infection.
Why can a virus behave differently in different hosts?
A virus may infect more than one species but produce different disease outcomes. The research will investigate how variations in host immune recognition and downstream responses contribute to these differences.
How do viruses avoid immune detection?
Some viruses have developed mechanisms that interfere with the host's immune response. These mechanisms are often described as viral immune evasion.
The project will investigate how viruses evade or manipulate innate immune responses and whether these strategies work differently depending on the immune system of the host species.
What determines whether a virus can cross a species barrier?
By combining comparative immunology and molecular virology, the research aims to identify biological factors that may help explain why some viruses adapt successfully to new hosts while others do not.
The broader objective is to improve understanding of the molecular interactions that determine the outcome of cross-species viral infections.
3. Main scientific areas covered by the PhD
The project brings together several areas of biomedical and biological research.
A. Innate immunology
The researcher will investigate the body's early defence mechanisms, particularly the processes through which cells recognise viral infections and initiate immune responses.
This includes understanding how pattern recognition receptors detect viral components and activate intracellular signalling pathways.
B. Pattern recognition receptor signalling
Pattern recognition receptors are important components of the innate immune system. Different receptors recognise different molecular features of pathogens.
The research will compare these pathways across host species to determine how differences in receptor activity and downstream signalling affect antiviral responses.
C. Molecular virology
Molecular virology examines viruses at the molecular and cellular levels, including how they enter host cells, replicate, interact with host proteins and influence cellular functions.
This project uses molecular virology to understand the relationship between viral characteristics and the immune systems of different hosts.
D. Host-pathogen interactions
Host-pathogen interaction research examines how infectious organisms and their hosts influence one another.
In this project, the focus is on how host immune systems respond to viral infections and how viruses may adapt to or interfere with those responses.
E. Comparative biology
The comparative approach is important because the research is not limited to one host species. It will examine similarities and differences in immune-recognition pathways across different animals.
Understanding these differences may provide insight into why certain pathogens can infect multiple species and how their behaviour changes when they enter a new host.
4. Why this research matters
Understanding zoonotic viruses is important because emerging infectious diseases can have consequences for human health, animal health, agriculture and global public health.
The ability of a virus to move from one species to another is influenced by several factors, including the compatibility between the virus and the biological systems of its new host.
Innate immune recognition is one of the mechanisms that can determine whether an infection is controlled or progresses.
The research may contribute to:
Better understanding of the early immune responses involved in viral infections.
Identification of differences in immune-recognition mechanisms across animal species.
Improved knowledge of how viruses evade or manipulate host immune defences.
A clearer understanding of the biological factors associated with cross-species viral transmission.
Research that may support future approaches to predicting and preventing the emergence of novel viral pathogens.
The project is fundamental biomedical research. It is not an advertised clinical trial or a direct vaccine-development position. Its primary focus is understanding the molecular and immunological mechanisms behind viral infection and host responses.
5. Funding and financial support
The University of Cambridge describes the Pathology studentships as fully funded opportunities.
For this particular studentship, the advertised financial support covers:
A doctoral maintenance stipend at the current Research Council rate.
