Factors relating to host (impairment of local immunity) and to M. hominis (essentially selection of immune escape mutants and perturbation of the host cell) have been suggested as a basis for the disruption of the host-pathogen equilibrium and the appearance of clinical disorders [ 25].
Furthermore, the nervous system interacts with the immune system [ 52, 53], suggesting that the local immunity of diabetic patients with neuropathy may be altered.
Without specific, standard methods for measuring mucosal immunoglobulins, immune investigation lacks of basic tools to study and compare local immunity, and HIV research is severely hampered in one of its major aims, i.e. identify and reproduce protective responses to block HIV infection just at virus's major portals of entry.
Little is presently known about the nature and features of the immune response to SFT, and no accurate histological description of local immunity exists for this STS.
Based on our experimental data, we assume that the DNCB combined acetic acid induced pathogenesis of rat UC, led to the destruction of the intestinal mucosa, initiating abnormal changes in the immune system of the intestinal mucosa, and thereby disrupted the balance between local immunity and intestinal flora symbiosis.
Evaluating mucosal humoral immunity is important for understanding local immunity induced by HIV infection or vaccination and designing prophylactic strategies.
In addition, in vivo99mTcO4 – uptake levels of xenografts were not consistent with their in vitro99mTcO4 – uptake levels because various host factors such as vascularity and local immunity might have affected 99mTcO4 – uptake in vivo.
A complex protocol of data and specimen collection was applied, including an interview, pelvic exam for sexually active women, blood for serology and cell-mediated immunity, cervical secretions for local immunity and cells for HPV, Chlamydia trachomatis and gonorrhea testing.
