Abstract

When pre-B cells are isolated from bone marrow and incubated in vitro for several days, they spontaneously differentiate into LPS-reactive B cells. These newly produced B cells do not respond to another B cell mitogen, lipoprotein (Lp). The lack of Lp reactivity of newly produced B cells represents a qualitative difference between these cells and B cells in peripheral tissues that respond equally well to both LPS and Lp. Thus, responsiveness to different mitogens provides unique markers to identify B cells at early stages of development.

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
