  • A wave of CD8 T cells follows, with increasing numbers of macrophages, and if a sufficiently high dose of antigen is used for "immunisation," a striking polymorphonuclear leucocyte infiltrate may be observed.
  • polymorphonuclear leukocytes

Examples

  • Cerebrospinal fluid findings, suggestive but not pathognomonic, include polymorphonuclear pleocytosis and increased protein concentration with normal glucose levels.

    Academic text (1998)
  • Researchers found that elevated levels of polymorphonuclear leukocytes are often present during bacterial infections.

  • The connective tissue layer of the treated TMs had been invaded by abundant inflammatory cells, primarily polymorphonuclear leukocytes.

    Academic text (2005)
  • Other angiogenic factors were also involved in the angiogenic action, and inclusion of polymorphonuclear leucocytes attenuated angiogenic action by releasing neutrophil elastase.

    Academic text (2002)
  • In a healthy immune response, polymorphonuclear leukocytes like neutrophils play a crucial role in fighting infections.

  • The laboratory analyzed samples of polymorphonuclear cells to better understand their function in the immune system.

Morphology

polymorphonuclear = nuclear (opaque) = poly + morpho + nucleus + ar

The word is built from recognizable Greek-derived elements, but the specialized medical meaning 'having a nucleus with several lobes' is not easily inferred by an average learner.

Etymology

Polymorphonuclear comes from three parts: poly- 'many', morph- 'shape', and nuclear 'of the nucleus'. So it describes something like a cell whose nucleus has many parts or lobes, which is why doctors use the word for certain white blood cells.
