Cell Injury, Repair & Inflammation
25 Previous Year Questions
CELL INJURY & CELL DEATH (Q1-Q12)
- A) Nuclear changes (karyolysis)
- B) Mitochondrial dysfunction
- C) Lysosomal rupture
- D) Plasma membrane disruption
The earliest biochemical change in cell injury is mitochondrial dysfunction leading to decreased ATP generation. Loss of ATP affects the Na+/K+ ATPase pump, resulting in cell swelling - the earliest morphological change. (Robbins Basic Pathology)
- A) Karyorrhexis
- B) Fatty change
- C) Hydropic change (cellular swelling)
- D) Coagulation necrosis
Reduced Na+/K+ ATPase activity (due to ATP depletion) causes sodium and water to accumulate inside the cell, resulting in cellular swelling - the hallmark of early reversible injury. (Robbins Basic Pathology)
- A) Cellular swelling
- B) Fatty change
- C) Plasma membrane blebbing
- D) Mitochondrial densities (flocculent)
Amorphous (flocculent) densities in mitochondria are a morphological feature of IRREVERSIBLE cell injury, signaling the point of no return. Blebs, swelling, and fatty change are reversible. (Robbins Basic Pathology)
- A) 30-40 seconds
- B) 1-2 minutes
- C) 20-30 minutes
- D) 2-3 hours
Myocardial cells become noncontractile after 1-2 minutes of ischemia but may not die until 20-30 minutes. Morphologic features appear by EM within 2-3 hours but are not visible by light microscopy until 6-12 hours after death. (Robbins Basic Pathology)
- A) Liquefactive necrosis
- B) Fat necrosis
- C) Granulomatous inflammation (TB)
- D) Gangrenous necrosis
Caseous necrosis appears as amorphous, granular, cheesy material (grossly). Microscopically, it is acellular with no tissue architecture. It is most classically associated with Mycobacterium tuberculosis. (Robbins Basic Pathology)
- A) Myocardial infarction
- B) Renal infarction
- C) Brain infarction
- D) Splenic infarction
The brain is unique - infarction causes LIQUEFACTIVE necrosis because the brain tissue is rich in lipids and proteolytic enzymes. All other solid organs undergo coagulative necrosis in ischemia, where the cell outline is preserved but the nucleus disappears. (Robbins Basic Pathology)
- A) It always causes inflammation
- B) It involves cell swelling
- C) It is a programmed, regulated process with no inflammation
- D) It is always pathological
Apoptosis is "clean" cell suicide - cells shrink, chromatin condenses, and apoptotic bodies are phagocytosed without eliciting an inflammatory reaction. Necrosis always causes inflammation. Apoptosis can be physiological (e.g., embryonic development). (Robbins Basic Pathology)
- A) DNA damage beyond repair
- B) Accumulation of misfolded proteins
- C) Deprivation of survival signals
- D) Acute hypoxia leading to ATP depletion
Severe ATP depletion from acute hypoxia leads to NECROSIS, not apoptosis. Apoptosis is triggered by DNA damage, loss of survival signals, and ER stress from misfolded proteins. (Robbins Basic Pathology)
- A) Pure apoptosis triggered by caspases
- B) A form of cell death with features of both necrosis and apoptosis, regulated by TNF signaling
- C) Cell death associated with inflammasome activation
- D) Autophagy-driven cell death
Necroptosis is triggered by TNF and shows features of both necrosis and apoptosis but is mechanistically distinct - it does NOT depend on caspases. Pyroptosis (option C) involves inflammasome activation and release of proinflammatory cytokines. (Robbins Basic Pathology)
- A) Cyclooxygenase (COX)
- B) Lipoxygenase
- C) Phospholipase A2
- D) Sphingomyelinase
Phospholipase A2 is activated by inflammatory stimuli and cleaves arachidonic acid from membrane phospholipids. AA is then metabolized by COX (to prostaglandins/thromboxane) or lipoxygenase (to leukotrienes/lipoxins). (Robbins Basic Pathology)
- A) Lipid peroxidation of membranes
- B) Cross-linking of DNA strands
- C) Fragmentation of polypeptides
- D) Increasing intracellular calcium
ROS damage cells by lipid peroxidation (membrane injury), oxidative modification of proteins (fragmentation), and DNA crosslinking/strand breaks. Increased intracellular calcium is a consequence of membrane pump failure from ATP depletion, not a direct ROS mechanism. (Robbins Basic Pathology)
- A) Normal tissue with hypercalcemia
- B) Dead/necrotic or damaged tissue with NORMAL serum calcium
- C) Normal parathyroid tissue
- D) Normal serum calcium and normal tissue
Dystrophic calcification occurs in abnormal (necrotic, injured) tissues despite normal serum calcium levels. Metastatic calcification occurs in NORMAL tissues when serum calcium is high. (Robbins Basic Pathology)
INFLAMMATION (Q13-Q22)
- A) Macrophages
- B) Lymphocytes
- C) Neutrophils
- D) Eosinophils
Neutrophils are the first responders in acute inflammation (within 6-24 hours). They are replaced by monocytes/macrophages at 24-48 hours. Neutrophils live 1-2 days and undergo apoptosis at inflammatory sites. (Robbins Basic Pathology)
- A) Bradykinin
- B) Histamine
- C) C3a
- D) Leukotriene B4
Histamine is released from mast cells, basophils, and platelets and is the FIRST mediator released in acute inflammation. It causes vasodilation and increased vascular permeability in the immediate phase (within minutes). (Robbins Basic Pathology)
- A) C3b
- B) C4b
- C) C5a
- D) C1q
C5a is the most potent chemotactic factor derived from the complement system. It also activates mast cells to release histamine, increasing vascular permeability. C3b is the major OPSONIN. (Robbins Basic Pathology)
- A) Random movement
- B) Adhesion to blood vessels
- C) Unidirectional locomotion toward a chemical gradient
- D) Phagocytosis of bacteria
Chemotaxis is defined as unidirectional locomotion of leukocytes along a chemical gradient (chemoattractants). This distinguishes it from random movement (chemokinesis). Key chemotactic agents: C5a, LTB4, IL-8 (CXCL8), and bacterial products (fMLP). (Robbins Basic Pathology)
- A) IL-1
- B) TNF-alpha
- C) Histamine
- D) Prostaglandin E2
Histamine is stored preformed in mast cell granules and is released immediately upon activation. IL-1, TNF-alpha, and prostaglandins are all NEWLY SYNTHESIZED mediators requiring gene transcription or enzymatic activity. (Robbins Basic Pathology)
- A) Slow-reacting substance of anaphylaxis (SRS-A)
- B) Platelet activating factor
- C) Eotaxin
- D) Lipoxins
LTC4, LTD4, and LTE4 together constitute SRS-A (slow-reacting substance of anaphylaxis). They increase vascular permeability and cause bronchoconstriction. LTB4 is the most potent neutrophil chemoattractant among leukotrienes. (Robbins Basic Pathology)
- A) Promote neutrophil recruitment
- B) Increase vascular permeability
- C) Suppress inflammation by inhibiting neutrophil adhesion and chemotaxis
- D) Activate mast cells
Lipoxins are generated from arachidonic acid via the lipoxygenase pathway. Unlike leukotrienes, they have ANTI-INFLAMMATORY actions - they inhibit neutrophil chemotaxis and adhesion to endothelium, helping resolve inflammation. (Robbins Basic Pathology)
- A) Plasma cell
- B) Giant cell (Langhans)
- C) Epithelioid macrophage (activated macrophage)
- D) CD8+ T cell
The epithelioid cell (activated macrophage with abundant pink granular cytoplasm resembling epithelium) is the defining and most important cell of a granuloma. Giant cells (Langhans) are formed by fusion of these activated macrophages. The lymphocytic collar consists of T cells releasing IFN-gamma, which drives macrophage activation. (Robbins Basic Pathology)
- A) IL-4
- B) IL-10
- C) IFN-gamma (Interferon-gamma)
- D) IL-6
IFN-gamma, released by CD4+ Th1 T cells (the lymphocytic collar in granulomas), is the primary mediator that activates macrophages into epithelioid cells and drives granuloma formation. (Robbins Basic Pathology)
- A) Defective opsonization
- B) Delayed umbilical cord separation and recurrent infections (defective chemotaxis/adhesion)
- C) Neutropenia
- D) Defective respiratory burst
LAD is caused by deficiency of beta-2 integrins (CD18), impairing leukocyte adhesion and chemotaxis. Clinically: delayed separation of umbilical cord at birth, recurrent bacterial infections, and absence of pus formation. (Robbins Basic Pathology)
TISSUE REPAIR & WOUND HEALING (Q23-Q25)
- A) Dense collagen and spindle fibroblasts
- B) Proliferation of fibroblasts and thin-walled capillaries in a loose ECM with admixed macrophages
- C) Caseous material with Langhans giant cells
- D) Fibrin deposition with neutrophil infiltration
Granulation tissue is the hallmark of early repair (NOT the same as a granuloma!). It consists of new capillaries (angiogenesis), fibroblasts, and loose ECM - classically described as pink, granular tissue with a "beefy red" gross appearance. Macrophages are the dominant inflammatory cell here. (Robbins Basic Pathology)
- A) Decreased fibroblast migration
- B) Impaired collagen synthesis (prolyl hydroxylase requires vitamin C)
- C) Reduced angiogenesis
- D) Defective macrophage function
Vitamin C (ascorbic acid) is an essential cofactor for prolyl hydroxylase and lysyl hydroxylase, enzymes required for collagen cross-linking and stabilization. Deficiency leads to weak collagen, impaired healing, and scurvy. (Robbins Basic Pathology)
- A) Adequate vascular supply
- B) Glucocorticoid (steroid) therapy
- C) Vitamin C supplementation
- D) Aseptic surgical technique
Glucocorticoids inhibit TGF-beta production, which is required for collagen deposition by fibroblasts. They are potent anti-inflammatory agents that delay wound healing. Other factors that delay healing include: diabetes, malnutrition (especially protein/Vit C deficiency), infection, and poor perfusion. (Robbins Basic Pathology)

Myocardial cells become non-contractile after only 1-2 minutes of ischemia - this is very early functional loss. But cell DEATH occurs at 20-30 minutes. Morphological changes appear by EM at 2-3 hours and by light microscopy at 6-12 hours. Tip: Function lost → 1-2 min | Cell dies → 20-30 min | EM changes → 2-3 hrs | LM changes → 6-12 hrs
Splenic infarction causes coagulative necrosis (like most solid organs). Brain infarction is the EXCEPTION - it causes liquefactive necrosis because the brain is rich in lipids and proteolytic enzymes, causing the tissue to liquefy. Tip: Brain = Liquefactive. All other solid organs = Coagulative.
That is the property of NECROSIS, not apoptosis. Apoptosis is a clean, programmed death - apoptotic bodies are neatly packaged and phagocytosed by macrophages without triggering inflammation. This is a classic differentiating point. Tip: Necrosis = always inflammation | Apoptosis = NO inflammation
Necroptosis has features of BOTH necrosis and apoptosis but is caspase-independent. It is triggered by TNF via RIPK1/RIPK3 pathway. Pyroptosis (not necroptosis) is associated with inflammasome activation. Tip: Necroptosis = TNF-triggered, caspase-independent, features of both N+A
COX acts AFTER arachidonic acid has already been released. The enzyme that liberates AA from membrane phospholipids is Phospholipase A2. Think of it as the "unlocking" enzyme, and COX/Lipoxygenase as the "processing" enzymes. Tip: Phospholipase A2 → releases AA → COX → Prostaglandins | Lipoxygenase → Leukotrienes

Review Your Mistake
LTB4 is a potent chemotactic agent (attracts neutrophils), NOT the primary mediator of vascular permeability in the immediate phase. Histamine is the FIRST mediator released (preformed, stored in mast cell granules) and is responsible for the immediate transient increase in vascular permeability.
| Phase | Mediator | Timing |
|---|---|---|
| Immediate transient | Histamine | 0-30 min |
| Delayed prolonged | Leukotrienes, Bradykinin | Hours |
| Chemotaxis | LTB4, C5a, IL-8 | - |
Tip: Histamine = First + Fastest. LTB4 = Chemotaxis, not permeability.
C5a is the most potent chemotactic complement fragment. Also remember:
- C3b = best opsonin
- C5a = best chemotactic agent + activates mast cells
- C3a, C4a, C5a = anaphylatoxins
- C5b-9 = Membrane Attack Complex (MAC) → cell lysis

The epithelioid macrophage (activated macrophage) is the defining and most important cell of a granuloma. It gets its name from its resemblance to epithelial cells - abundant pink granular cytoplasm with indistinct cell borders.
| Cell | Role in Granuloma |
|---|---|
| Epithelioid macrophage | Most important cell - central to granuloma |
| Langhans giant cell | Fused epithelioid macrophages (peripheral nuclei) |
| CD4+ T cells | Lymphocytic collar - release IFN-gamma |
| CD8+ T cells | NOT the key cell in granuloma |
Tip: Granuloma = Modified macrophage (epithelioid cell) surrounded by CD4+ T lymphocytes releasing IFN-gamma. CD8+ cells are cytotoxic T cells - not the hallmark of granulomas.
