Abstract:
In the Reticulo-Endothelial System (RES), named at present Accessory Immune System (AIS), two chief groups of cells can be recognized: 1--Antigen-presenting cells: Dendritic cells 2--Antigen-processing cells: Macrophages (or Histiocytic cell) True malignant Langerhans cell neoplasm has not been yet clearly demonstrated. Finally, it is important to note that marcrophages and dentritic cells are commonly observed as relative cells in numerous malignant tumors (carcinomas, sarcomas, lymphomas, etc) However, their precise role has yet to be determined.

Lymphoid Cells and Tissues
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
Functions of the Lymphatic and Immune System
The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...
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...
Introduction to Lymphatic and Immune System
The immune responses can be categorized into two types: innate and adaptive. Innate immunity comprises nonspecific defenses we are born...

Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...
