natita [175]

Answer:

Microfilaments, Intermediate filaments and microtubules

Explanation:

Three distinct elements make up the cytoskeleton in eukaryotic cells are:

1. Microfilaments or actin filaments which are composed of actin proteins. The functions of those filaments are: muscle contraction (myosin heads move “walk” on actin filaments), the movement of the cell,  intracellular transport, maintaince of the cell shape..

2. Intermediate filaments which can be made of vimentins, keratin, lamin, desmin… Their functions are: the maintenance of cell shape, anchoring organelles, structural components of the nuclear lamina, cell-cell and cell-matrix junctions…

3. Microtubules are filaments polymers of alpha and beta tubulin. Their roles are in intracellular transport (associated with motor protein dyneins and kinesins),  formation of the axoneme of cilia and flagella, formation of the mitotic spindle.

Once they have penetrated the first line of defense, which microorganisms do natural killer (nk) cells actively attack?
stellarik [79]

Once they have penetrated the first line of defense, NK cells are the principal defenders against only tumor cells or virally infected cells.

<h3>What are NK cells?</h3>

A particular class of immune cell that contains granules, or tiny particles, that contain enzymes that can destroy cancer cells or virus-infected cells. White blood cells, or NK cells, are one type of them. known as NK-LGL and natural killer cell, respectively.

Natural killer (NK) cells are effector lymphocytes of the innate immune system that regulate various tumour types and bacterial infections by preventing their growth and subsequent tissue damage.

Human NK cells are created from hematopoietic stem cells (HSCs), and as they transition from being CD56high to CD56low, KIRs, CD57, and NKG2C are expressed on terminally differentiated NK cells. During this time, NKG2A is gradually lost.
