SMAC
Apoptosis both pathways effector
Caspase 3, and 7
Apoptosis extrinsic pathway initiator
FAS ligand
TRAIL Ligand
Apoptosis initiator caspases?
Caspase 8,9,10
Step ladder pattern seen in which process after cell injury
Apoptosis - due to DNA fragmentation
Smear pattern seen in which process after cell injury
Necrosis due to groups of cell bring destroyed
Leucotoxins mainly act by causing
Apoptosis
Also Necrosis but MAINly apoptosis
Coagulative Necrosis shows what kind of cellular appearance
Tomb stone Cells, nuclear death, cell membrane intact
Fibrinoid Necrosis seen in
Rheumatoid arthritis - pan aschoff nodules
AAT is due to which enzyme deficiency
Alpha 1 antitrypsin deficiency
: leads to protein accumulation in lungs and liver(site of a1at production) loss of enzyme production leads to Liver enlargemet, as lungs weaken
Cystic fibrosis pathophysiology
Cause -CTFR defect on chromosome 7, defect in transport of Na, sweat chloride, thick body secretions, sinus lungs mucus filled and have infections, gi obstruction,
Huntington disease is due to deficient
Huntingtin enzyme - leads to memory loss, lack of attention
•age 30 onwards is called = juvenile, seen in old age also, enlarged lateral ventricle on mri, difficult Co ordination, balance
Zenkers waxy degeneration is seen in
Skeletal muscle after infections with High grade fevers like Typhoid
Extracellular hyaline change is normal finding in
Newborn
Examples of dystrophic calcification (RATT)
Rheum arthritis
Atherosclerosis
Tb lymph node
Tumors - papillary tumor thyroid
Metastatic calcification features
RAISED SERUM CALCIUM LEVELS
seen in living tissue
Seen in sarcoidosis. Multiple myeloma, renal failure,
Found in organ which lose acid to have alkaline medium = lungs, kidney, stomach!!
SIRTUINS are responsible for what
Keeping Cells young
List enzymatic antioxidants (3)
1.(SOD) Superoxide dismutase
2.Catalase
3.Glutathione peroxidase
List of non enzymatic antioxidants
Vit e, albumin, transferin, cysteine, glutathione, cerruloplasmin
Light microscopy fixative
10% neutral buffer formalin
Electron microscopy fixative
Glutaraldehyde
PAS stain stains what
Glycogen, fungus
