Most importantly, it should be kept in mind that the large majority of the patients treated with gene therapy for two forms of lethal congenital immunodeficiency are now alive and healthy – thanks to this 'risky' therapy (Aiuti et al, 2009; Hacein-Bey-Abina et al, 2008; Howe et al, 2008).
Failure of osteoclast formation or activity results in osteopetrosis, some forms of which are lethal because of attendant immunodeficiency and increased risk for infection and recurrent fractures.
Passive antibody administration protects severe combined immunodeficiency (SCID) mice against lethal Y. pestis infection (39).
This relationship correlates with protective responses against infectious pathogens including Marek's disease virus leading to lethal tumours in chickens and human immunodeficiency virus infection progressing to AIDS in humans.
We further show that chronic infection with MHV68 rescued HOIL-1, IL-6, Caspase-1 and Caspase-1 Caspase-11-deficient miCaspase-1 Caspase-11-deficiention, thereby masking the genetiCaspase-1 Caspase-11-deficient MHV68-negative miCaspase-1 Caspase-11-deficient
Loss of FOXP3 function leads to a lack of Tregs, resulting in lethal autoaggressive lymphoproliferation, whereas FOXP3 overexpression results in severe immunodeficiency [ 14, 15].
18 This gene plays a crucial role in the generation of CD4+CD25+ Tregs, and the loss of Foxp3 function leads to a lack of Tregs, resulting in lethal autoaggressive lymphoproliferation, whereas overexpression of Foxp3 results in severe immunodeficiency.
The use of highly active antiretroviral therapy (HAART) resulted in a significant decrease in morbidity and mortality in patients with human immunodeficiency virus (HIV) infection [ 1], turning this lethal infection to a chronic ambulatory disease.
CmR: Chloramphenicol-resistant; GUD: Genital ulcer disease; KanR: Kanamycin-resistant; HIV: Human immunodeficiency virus; MIC: Minimum inhibitory concentration; MLC: Minimum lethal concentration; MRSA: Methicillin-resistant Staphylococcus aureus; PcR: Penicillin-resistant; STI: Sexually-transmitted infection; TcR: Tetracycline-resistant; TMPR: Trimethoprim-sulfamethoxazole-resistant.
Primary immune deficient patients such as those with X-linked lymphoproliferative disease and individuals with acquired immune deficiency secondary to immunosuppressive drugs for organ transplantation or individuals infected with human immunodeficiency virus are also at very high risk for lethal LPD.
