In Silico Modelling of Toll-Like Receptor Pathways in Human Epidermal Keratinocytes

Abstract

The discovery, that the epithelial surfaces, such as skin, can actively programme systemic immune responses has revolutionized our understanding of human immunity. To fully harness this exciting finding, it is essential to dissect the molecular interactions orchestrating the process of immune programming. Our recent research identified the key molecular networks regulating antigen presentation by human skin immune cells, and documented the power of stochastic modelling for prediction of different functional immunity outcomes (Polak et al, 2017, Nature: Scientific Reports 7:668; Livigni et al Nature Protocols, 2018, in press).

The aim of this PhD project is to identify, reconstruct, and model in vitro and in silico, gene regulatory networks of host-pathogen interactions in human skin, developing a novel platform for in silico investigation of immunity.

Specific objectives:
1. Identification of molecular networks in human skin.
2. Assembling of an in silico representation of the key gene regulatory network.
3. Dynamic modelling of the in silico model to investigate immune responses in human intact epidermis.
4. Targeting human keratinocytes to modulate function.

Title Genetic Algorithm 
Description I have developed a genetic algorithm which is able to estimate parameter values for mathematical models. These parameter values can be utilised to enhance the predictive capabilities of in silico models. 
Type Of Material Computer model/algorithm 
Year Produced 2020 
Provided To Others? No  
Impact This algorithm is still in development, but it appears to be an improvement on current techniques for parameter estimation and we are in the process of submitting a publication.

Results and Impact We ran a Hampshire - wide competition for secondary school pupils. The competition required students to develop their own computer or board game that teaches the player about skin immunology. Participants had to produce a video to explain their game and finally present their games at the grand final in front of the judging panel. We will also be organising a showcase session for the games at a local board game cafe.

Primary Audience Public/other audiences
Results and Impact I attended the New Forest and Hampshire County Show in July 2019. We ran a stall with an activity aimed at educating the public on the importance of skin immunology. Around 100 children plus their parents/carers took part in the activity, where they had to make a model of the skin using salt dough.
