The Cell as a System
Why cell biology — not a parts list — is the operating system of medicine.
Membrane Biophysics & Transport
Lipid bilayers, channels, pumps and the currencies of compartmentalisation.
Protein Structure, Folding & Quality Control
From Anfinsen's dogma to chaperones, the UPS, and the unfolded-protein response.
Organelles & the Secretory Pathway
ER, Golgi, lysosomes, and the COP/clathrin logistics network that keeps a cell alive.
Cytoskeleton & Cell Motility
Actin, microtubules, intermediate filaments — and the motors that walk on them.
Cell Junctions & the Extracellular Matrix
Tight, adherens, desmosomal, gap — and the matrix that holds tissues together.
Bioenergetics & Mitochondrial Cell Biology
Membrane potential, ROS, mitophagy, and the inheritance of mitochondrial disease.
Signal Transduction
GPCRs, RTKs, second messengers, and why most prescription drugs target signalling.
Gene Expression & Chromatin
From nucleosomes to enhancers: how cells choose which genes to read.
RNA Biology & Translation
Splicing, ncRNAs, mRNA capping and the ribosome — and the drugs that reach them.
Cell Cycle & Checkpoints
CDKs, cyclins, restriction point — and the chemotherapy that exploits them.
Cell Death Pathways
Apoptosis, necroptosis, pyroptosis, ferroptosis — and why the difference matters clinically.
DNA Damage & Repair
Lesions, sensors, repair pathways — and the synthetic-lethality oncology revolution.
Cancer Cell Biology
Hallmarks, plasticity, microenvironment, metastasis — beyond mutation lists.
Stem Cells, Development & Regeneration
Pluripotency, niches, organoids, and what cell therapy can — and cannot — yet do.
Cellular Immunology Essentials
Innate sensors, T- and B-cell biology, immune synapses, and the cells we steer with checkpoint blockade.
Methods: Microscopy, Omics & Genome Editing
What you actually need to read a modern cell-biology paper.
Translational Frontier: Cell & Gene Therapy
What cell biology has put in clinic — and what it has promised but not yet delivered.
