Module Catalogue 2024/25

Pre Requisite Comment

The module builds on basic knowledge of cell biology, the immune system and microbiology as taught in the first two stages of the Biomedical Sciences course and therefore assumes knowledge of basic cellular biology, microbiology, immunology, genetics and physiology as taught in the first and second stages of the Biomedical Sciences BSc Honours course.

Aims

Breathing, feeding and reproduction are all dependent on healthy mucosal surfaces that have evolved over millions of years to mediate simultaneously two fundamentally contradictory functions: facilitating exchanges between the inside and outside of the human body and protect us from infectious diseases. When the balances/homeostasis of these mucosal functions are disrupted important and a broad diversity of pathologies can develop.

The module aims to develop knowledge and understanding of the:

•key features of the human mucosal innate and adaptive immune systems and their dynamic interactions with the microbiota in the digestive, reproductive and respiratory tracts and their roles in health and disease
•molecular and genomic techniques used to investigate the human microbiota including its taxonomic diversity and metabolic capabilities
•complex interplay between the mucosal immune systems, the microbiota and pathogens – including selected viruses, bacteria and microbial eukaryotes (protozoa and fungi)
•clinical importance of selected diseases of the digestive and respiratory tracts
•physiology of the lung, and pathogenesis of a range of lung diseases
•molecular and pathological changes in lung disease and the diagnostic tools and treatments available for these.

Outline Of Syllabus

The module will be structured into 2 strands;

Strand A: Human-microbe interactions in health and disease at mucosal surfaces which will provide;

•introduction to mucosal surfaces including epithelial/immunocyte/microbiota interaction at the different mucosal surfaces in health and disease
•Bacteroidetes and glycan metabolism
•microbiota-bacterial/fungal/protozoa/viral pathogen interactions


Strand B: Respiratory disease which will provide;

•a review of the structure of the lungs, the mechanics of breathing and the techniques applied to the assessment of lung function
•drugs affecting the respiratory system
•obstructive and restrictive lung disease
•occupational and infectious lung disease
•pathophysiology of cystic fibrosis

Intended Knowledge Outcomes

On successful completion of this module the students will be able to:

K1) Describe the fundamental role of the mucosal innate and adaptive immune systems interactions with the microbiota in the digestive, reproductive and respiratory tracts in health and disease.

K2) Recognise the clinical importance of host-microbiota-pathogen interactions in the context of selected infectious diseases, inflammatory bowel diseases and selected lung diseases.

K3) Relate lung structure and function with pathogenesis of a range of lung obstructive and restrictive diseases and infectious diseases.

K4) Describe the current tests used in the diagnosis of respiratory diseases and their corresponding treatment options.

Intended Skill Outcomes

On successful completion of this module the students will be able to:

S1) Critically interpret and synthesise complex information relating to human mucosa-microbiota interactions across the spectrum ranging from health to disease status in the digestive, reproductive and respiratory tracts.

S2) Efficiently search and critically read the literature

S3) Communicate efficiently in writing

Teaching Rationale And Relationship

Lectures and lecture materials will provide students with key information to achieve the learning outcomes of the module. The first seminar session will prepare students for the in course assessment consisting of an extended essay and provide papers and questions to be read in advance of seminars 2 and 3. Seminars 2 (end of strand A) and 3 (end of strand B) will familiarise the students with reading scientific papers and prepare them for the final MCQ style exam questions and increase their understanding of the taught materials through discussion and a Q&A session.

Private study and active learning on the part of the students is essential. These will allow students to extend their knowledge through reading of textbooks, journal articles and other recommended reading.

Assessment Rationale And Relationship

The examination provides evidence of individual knowledge and understanding of the topics. The extended essay supports the students’ development in finding and critically analysing current literature and their written communication skills.
