Answer:
Non- targeted cell lacks intracellular receptor for these hormone.
Explanation:
Receptors that are found on the cell surface are called cell surface receptor and those which are found inside the cell are called intracellular receptors. Intracellular receptor binds to lipophilic molecules. Each receptor binds specifically to a particular ligand or signal molecule.
So even though testosterone and estrogen can diffuse in every cell they will only affect those cell which have specific receptor which can bind to these hormones and then regulate the transcription of a specific gene in the nucleus.
So only those cells will respond to testosterone and estrogen who have specific intracellular receptors for them.
Lymphocytes or natural killer
is one of the component of innate immune system where it acts as defense
mechanism of the body that are always present to mobilize and fight bacteria,
viruses and microbes at the site of infection.
Moreover, innate immune
system also refers to non-specific recognition of certain molecular
shapes on pathogens. Other components of innate immune system includes physical epithelial
barriers, phagocytic leukocytes, dendritic cells, and circulating plasma
proteins.
