Perturbation of early development of the immune system by normal adult lymphoid cells
Abstract:
Seven-day-old C57BL/10 mice injected with 3 X 10(6) normal adult lymph node cells (NAL) from syngeneic donors were compared with uninjected littermates when 5 to 7 wk old. The direct PFC response to sheep erythrocytes was suppressed by 60%. Responses to PHA and Con A but not LPS were suppressed by 60 to 90%. Primary and secondary (after skin graft rejection) MLR responses were suppressed by 30 to 40%. Active suppressor cells were demonstrable in these mice. Skin grafts incompatible for H-2 were rejected in normal time. NAL derived from adult mice conferred the effect, but not cells from 7-day-old donors. Mice inoculated with Rous sarcoma virus within the 1st day of life and 3 X 10(6) NAL at 7 days of age displayed up to 5-fold increased incidence of primary sarcomas.

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...
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...

B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
