Pathology of Inflammation: Acute vs Chronic Explained: Vascular & Cellular Events + Key Mechanisms

Welcome to this comprehensive 18-minute lecture on *Inflammation* — your all-in-one path to mastering both acute and chronic inflammation, its vascular & cellular events, and the molecular mechanisms behind them. --- 🔍 What You Will Learn In this video, I walk you through: 1. *Definition & Purpose of Inflammation* What inflammation is, and why it’s central to immune defense and tissue repair The difference between *acute inflammation* and *chronic inflammation* 2. *Cardinal Signs & Hallmarks* Redness, heat, swelling, pain, loss of function How they emerge (vasodilation, increased permeability, etc.) 3. *Acute vs Chronic Inflammation – Comparison by Key Dimensions* | Parameter | Acute | Chronic | |----------|--------|---------| | Onset | Rapid | Slow / insidious | | Duration | Hours to days | Weeks, months, years | | Cause | Infection, trauma, toxins | Persistent pathogens, autoimmune, long-term irritants | | Cellular Players | Neutrophils, fluid exudate | Macrophages, lymphocytes, fibroblasts | | Exudate / Features | Exudative, edema, fibrin, purulence | Granulation tissue, fibrosis, scarring | | Outcome | Resolution or abscess formation | Tissue destruction, repair, fibrosis | 4. *Vascular Events in Acute Inflammation* Vasodilation, increased blood flow Increased vascular permeability & leakage Stasis, exudation, effusion 5. *Cellular Events in Acute Inflammation* *Margination & Marginal Flow* *Rolling & Selectin-mediated interactions* *Adhesion & Integrin activation* *Transmigration / Diapedesis* *Chemotaxis* (how cells follow chemical gradients) *Opsonization & Opsonins* *Phagocytosis* (Also touched upon the influence of diabetes on inflammation dynamics) 6. *Outcomes & Resolution* How acute inflammation resolves When it becomes chronic & what drives that Tissue repair, scarring, and pathological sequelae --- 🧠 Why This Matters (Relevance) Inflammation is central to nearly every disease process — from infections, autoimmune disease, cardiovascular disease, diabetes complications, neuroinflammation, cancer, etc. Understanding the *mechanisms* (rolling, chemotaxis, phagocytosis) is critical for medicine, pathology, immunology, research, and clinical reasoning. --- ⏱️ Time-Stamps / Chapters (for convenience & SEO) 00:00 – Introduction & Definitions 01:25 – Cardinal signs of inflammation 02:40 – Acute vs Chronic: comparative table 04:30 – Vascular events in acute inflammation 06:50 – Margination & Rolling 08:10 – Adhesion & Integrin activation 09:30 – Transmigration / Diapedesis 11:00 – Chemotaxis & gradient sensing 12:20 – Opsonization & opsonins 13:40 – Phagocytosis steps 15:20 – Influence of diabetes on inflammation 16:30 – Outcomes, resolution & chronic progression 17:40 – Summary & take-home messages --- ✅ Pro Tips (For You, the Viewer) Use the timestamps above to jump to key sections you’re interested in.
