Abstract:
In the past several years our understandings for Hodgkin's lymphoma have significantly progressed, and we can now recognize two fundamental bases of Hodgkin's lymphoma: germinal center B cells as a cellular origin of Hodgkin and Reed-Sternberg (H-RS) cells and constitutively strong NF-kappaB activation as a biological base for H-RS cells. We can also define Hodgkin's lymphoma as being composed of H-RS cells with self-growth-promoting potential as malignant cells by constitutively strong NF-kappaB activation and surrounding reactive cells. Identification of molecules involved in constitutive and strong NF-kappaB activation in H-RS cells is important to understand the pathophysiology as well as transformation and developmental process of Hodgkin's lymphoma. Epstein-Barr virus latent membrane protein (LMP)-1, defective IkappaBalpha, IkappaB kinase activation and ligand-independent signaling by overexpressed CD30 have been clarified in the past several years. Involvement of JunB in overexpression of CD30 has been recently reported. Today, over a century and a half after the first report by Thomas Hodgkin, we at last obtained several keys to solving the mystery of Hodgkin's lymphoma on a biological basis.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
