Yet research on how to strengthen deficient immune responses is seldom reported -- and medications that safely strengthen immunity do exist.
The acute or severe form of the disease is associated with deficient cell immunity, high antibodies (Abs) levels, and preferential secretion of type 2 cytokines [4].
For example, CHH patients, with mutations in the RNA component of the ribonucleoprotein complex RNase MRP, present with disproportionate short stature and deficient cellular immunity [28], [37], reminiscent of the collagen X murine metaphyseal dysplasia and hematopoietic defects.
In an article from the laboratory of the Nobel laureate Zinkernagel (14), the investigators showed that antibody escape variant viruses were more likely to arise in animals with deficient cellular immunity.
Deficient humoral immunity specific for rhinoviruses is associated with AECOPD requiring hospitalisation, and may partly explain why some COPD patients have an increased exacerbation risk following respiratory viral infections.
These immunodeficient mice lack B and T lymphocytes (scid phenotype), and also lack NK cells and are deficient in innate immunity due to knockout of the IL-2Rγ IL-2Rγ
Since mice deficient in specific immunity exhibit similar initial dynamics as wild-type mice it is generally viewed that the initial control of parasite is due to either limitation of resources (RBC) or innate immune responses.
However, since MVA is fully replication deficient, pre-existing immunity is unlikely to affect the immunogenicity of these vector vaccines to a great extent and did not prevent the induction of humoral responses to the expressed protein [35] [37].
Many investigators have noted deficient cell-mediated immunity in advanced cancer patients.
Deaths from measles with pneumonia or ARDS but without rash have been reported but mostly in patients with deficient cell-mediated immunity (2 – 6 ).
