Cell Death: Apoptosis, Necrosis, and Autophagy
Cell death occurs through distinct mechanisms including apoptosis, necrosis, and autophagy, each with unique molecular pathways and roles in development, homeostasis, and disease.
Cell dynamics Stem Cells and Regenerative Medicine
Stem cells are undifferentiated cells capable of self-renewal and differentiation into specialized cell types, with applications in regenerative medicine, disease modeling, and drug discovery.
Cell dynamics Cell Adhesion and Extracellular Matrix
Cell adhesion molecules and the extracellular matrix provide structural support, mediate cell-cell communication, and regulate tissue organization, migration, and signaling.
Membrane biology The Cytoskeleton: Structure and Dynamics
The cytoskeleton is a dynamic network of protein filaments that provides structural support, enables cell movement, facilitates intracellular transport, and drives cell division.
Cytoskeleton Mitochondria and Cellular Energetics
Mitochondria are double-membrane organelles that generate ATP through oxidative phosphorylation and serve as central hubs for metabolism, calcium homeostasis, and apoptosis regulation.
Organelle biology Cell Membrane Structure and Transport
The cell membrane is a selective permeability barrier composed of a phospholipid bilayer with embedded proteins, controlling the passage of molecules via passive and active transport mechanisms.
Membrane biology The Endomembrane System and Protein Trafficking
The endomembrane system is a network of membrane-bound organelles that synthesize, modify, sort, and transport proteins and lipids throughout the eukaryotic cell.
Organelle biology Cell Cycle and Cell Division
The cell cycle is the ordered series of events leading to cell division, regulated by cyclins, CDKs, and checkpoint mechanisms that ensure genomic integrity.
Cell dynamics Cell Signaling and Signal Transduction
Cell signaling is the process by which cells communicate with each other through signaling molecules, receptors, and intracellular transduction cascades.
