Structural Biology of the Cell
A.Y. 2024/2025
Learning objectives
The course objectives are the knowledge of the cellular mechanisms that regulate survival, proliferation and differentiation of eukaryotic cells, both animal and vegetal. Students will gain competences in understanding experiments and concepts related to the general field of cell biology and the ability to understand modern technologies of relevance to cell biology.
Expected learning outcomes
By the end of the course the student will be have built a strong background in the key cellular mechanisms controlling plant and animal differentiation and knowledge of the experimental approaches that are in different cellular model systems including cutting-edge technologies, and will have learned how to critically evaluate experimental data, and plan simple projects, approaching biological questions with a problem-solving attitude.

Course syllabus
The course will approach cell biology both from the perspective of the animal (Prof. Biffo) and the vegetal cell (Prof. Ezquer). Therefore two different modules will be proposed:
During the lectures of the animal's part, the following arguments will be dealt with: principles regulating actin filament (AFs) and microtubule (MTs) dynamics; the specific roles of AFs and MTs in plant cells with respect to animal cells; MT dynamics as the major determinant of cell wall structure and plant cell shape; protein complexes involved in MT nucleation (model of dispersed MTOcs) and MT dynamics in isodiametrically and tip growing cells; cell Biology in the laboratory; imaging technology and the cytoskeleton; structure and relevance of the cytoskeleton in disease and diagnostics; unconventional signaling through cellular shape; disease and target-oriented cell biology and the functional analysis of gene function by cell biology (data discussion).
In the vegetal cell part, specific structural aspects are introduced concerning the role of the cell wall architecture as well as other cellular components influencing mechanical and biophysical properties in plant tissues. Special emphasis will be placed on technical advances in plant structural biology research: from molecular, cell biology techniques, to advanced microscopy and cell wall analytical techniques. Invited international researchers will provide specific lessons to provide insights into modern technical approaches, career perspectives or new challenges in plant science (climate change, evolutionary aspects of plant development). The student will acquire knowledge regarding advanced techniques used to study cell growth and organ morphogenesis in plant cells.

Prerequisites for admission
The course deals with topics of advanced cell biology, therefore a basic preparation in molecular biology and cytology is highly advised. The plant biology requires basic background in plant botany and plant cell physiology.
Teaching methods
Powerpoint-assisted lectures and pdf documents (with scientific articles/lessons). The active participation of the student will be stimulated by scientific questions and discussions of specific topics during class, thus lecture attendance is highly preferred.
Invited lectures from external researchers working in research centers, academia and biotechnological companies will be included among the lesson program in order to provide career perspectives to students.

Teaching Resources
Lecture presentations, scientific articles and other teaching resources will be provided via the course Ariel website and refer to newly published sources. For a general textbook of Cell Biology the following is suggested: Cell Biology 3rd Edition, ELSEVIER, Editors Pollard, Earnshaw, Lippincott-Schwarts & Johnson (the book is not mandatory).
Assessment methods and Criteria
The evaluation will be done in two separate modules: First part: (Prof Biffo) animal cell part and second part (Prof. Ezquer) plant cell part. Average marks will be obtained from both modules by common evaluation from professors.
In the first part, students will be evaluated by a written exam consisting of multiple choice questions (25%), open questions (25%), recognition of structures (25%) and the conceptual elaboration of a scientific problem of cell biology (25%).
In the plant structural biology part, the exam will consist of 3-4 open questions and optional exercise (homework proposed during one of the lessons) will be taken into consideration.
During the course, past exam examples will be provided. Evaluation criteria are based on the verification of acquired skills (10/30), reasoning ability (10/30) and clarity of the answers (10/30). Examinations will last up to 2 hours.
