Formation of antibody in the newborn mouse: study of T-cell-independent antibody response
Abstract:
The ontogeny of immune responsiveness, as assayed by antibody formation in vitro, of mouse spleen lymphocytes to thymus-independent antigens is reviewed. Responsiveness to trinitrophenyl (TNP)-lipopolysaccharide and TNP-Brucella abortus appear soon after birth and one to two weeks before TNP-Ficoll or capsular polysaccharide of Streptococcus pneumoniae (SSS-III) elicits significant antibody formation. This hierarchy of responsiveness to antigens is also apparent in the CBA/N mutant mouse strain, which has a bone marrow-derived (B-) cell maturation arrest and fails to respond to either TNP-ficoll or SSS-III. These findings are interpreted to suggest sequential maturation of different populations or lines of B-lymphocytes, each of which can respond to a defined class of thymus-independent antigens. The implication for vaccine use in humans is that a late-appearing subclass of B-cells may be required for adequate immune responses to polyaccharide antigens.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

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...
