Can a percentage of total and immediate (hypothetical sub 1 second) T-Cell loss cause death to a typical adult?

What percentage of hypothetical immediate loss would yield rapid death under 1 minute?

What would the most likely cause of death be?

What size is a typical T-Cell in µM^3 ?

Is there an area or organ in the human body which holds the vast majority of T-Cells?

Greatly appreciated.

Here is wikipedia on T-cells.
T-cells function in the immune system which fights infections and cancers (to some degree) in the body.
They don't keep you body alive directly, they fight off attacks upon the body (from disease organisms or cancer).

Their loss would not cause an immediate death (even if they were all gone instantly), because you would have to die of an infection or cancer. That would take a while.

They are (mostly?) made in the thymus (the T in T-cell), but them distribute themselves throughout the body as they patrol around looking for things that should not be there (disease organisms and cancer cells).

Great, what about their size?
 
No.
