Signal Transduction by JAMES KAPIYA 6TH YEAR MEDICAL STUDENT UNZA-SOM - Molecular Biology-unza

Description

This comprehensive academic presentation on signal transduction provides a detailed exploration of cellular communication mechanisms, receptor types, and associated pathways crucial for understanding molecular biology and disease processes. The material explains how cells coordinate through chemical signals, detailing extracellular receptors such as G protein-coupled receptors (GPCRs), receptor tyrosine kinases (RTKs), integrins, toll-like receptors, and ligand-gated ion channels, alongside intracellular receptors for hormones like steroids and thyroid hormones. Key signaling pathways, including cAMP-dependent and MAP kinase cascades, are outlined, with emphasis on their roles in regulating cell growth, differentiation, and immune responses. The presentation also highlights the relevance of signal transduction dysregulation in diseases, particularly cancer, where mutations in pathways involving RAS, JAK-STAT, and PI3K contribute to oncogenesis and drug resistance. This resource is essential for medical students, molecular biology trainees, and researchers in Zambia, offering structured, exam-focused content for mastering cellular signaling concepts within a tertiary medical education context.
