Cellular mechanisms of necrosis

cellular mechanisms of necrosis Cell death may occur via at least two broadly defined mechanisms: necrosis or apoptosis necrosis is a cell death process generally occurring in response to trauma generated by external factors or overwhelming cellular injury.

Q i can't seem to get the different types of necrosis straight (liquefactive, fibrinoid, etc) any help a there are basically six distinct patterns of necrosis it's important to know about these, because they can give you a clue as to why the tissue died.

  • Cytomas will include a wider array of cellular markers, namely factors that contribute more directly to the highly malignant fea-tures of these tumors, such as tumor necrosis, which leads to poor patient prognosis physiological mechanism of necrosis in glioblastomas necrosis is a hallmark.
  • Apoptosis or necrosis apoptosis and necrosis are two major it is not clear if there is cellular death involving both the molecular mechanisms of apoptosis and those of necrosis cell death induced by removal of a cytokine required for cellular viability leads to the following.
  • Cell damage can occur as a result of an adverse stimulus which disrupts the normal homeostasis of affected cells depending on the extent of injury, the cellular response may be adaptive and where possible the stages of cellular necrosis include pyknosis.
