The immune system is a complex system of cells and molecules that can provide us with a
basic defense against pathogenic organisms. Like the nervous system, the immune system …

To pathogenic microparasites (viruses, bacteria, protozoa, or fungi), we and other mammals
(living organisms at large) are little more than soft, thin-walled flasks of culture media. Almost …

The T helper (Th) phenotypes, Th1/Th2, are acquired upon interaction of a naive T helper
cell and an antigen presenting cell (APC). Naive T helper cells may differentiate into either …

A major gap in our understanding of the immune response to pathogens and vaccines is
how closely the antigen specificity in the memory phase mimics repertoire that is rapidly …

L'objectif de cette thèse est d'une part l'étude de la stabilité des équilibres de certains
modèles épidémiologiques et d'autre part la construction d'un observateur pour l'estimation …

The phenomenon of immunological memory has been known for a long time. But, the
underlying mechanism is poorly understood. According to the theory of clonal selection the …

Type I hypersensitivity, which functions to protect the organism from parasites, is caused by
binding of antigen to IgE antibodies pre-attached to the cell surface of tissue mast cells and …

Using a variety of expression systems the number of available recombinant ovine cytokines
has increased steadily. This has led to the use of ovine cytokines as adjuvants to modulate …

Purpose. This work examines the effectiveness of synthetic peptide immunogens derived
from immunodominant T-cell epitopes as replacements for their intact parent protein in …

An HIV model incorporating immune response is considered. The basic reproduction
number is exhibited. The global stability of the virus free equilibrium is proved and the …
