The genotype was studied according to the 8 polymorphic genetic systems (Gm, Hp, Tf, Gc, ESD, PGM, ACP and ADA) in 73 children suffering from tuberculosis and 251 healthy children of the Tuvinian nationality.

Infection of mice with Dam(+) Salmonella resulted in the induction of host genes known to be indicators of IFN bioactivity and regulated by either IFN-alpha/beta (Mx1) or IFN-gamma (class II transactivator protein [CIITA] and inducible nitric oxide synthase [iNOS]) or by both IFN-alpha/beta and IFN-gamma (RNA-specific adenosine deaminase [ADAR1] and RNA-dependent protein kinase [PKR]) in a tissue-specific manner compared to uninfected animals.

Since the Mx1 promoter is IFN-alpha/beta specific and the Mx1 gene is not inducible directly by IFN-gamma, these data suggest a role of IFN-alpha/beta in the host response to Salmonella infection.

Finally, although no Dam(-) organisms were recovered from the liver or spleen after oral infection of mice, ADAR, PKR, Mx, and CIITA expression levels were elevated in these tissues relative to those in uninfected mice, suggestive of the distant action of a signaling molecule(s) in the activation of ISG expression.

Examples of new agents are: trastuzumab (Herceptin), a humanized monoclonal antibody that blocks the HER-2/neu proto-oncogene in combination with cytotoxic agents, is used in a percentage of breast cancer patients; signal transduction inhibitor of abl tyrosine kinase STI 571 (Glivec) has been shown to be an active treatment for chronic myeloid leukemia and GISTs; epidermal growth factor receptors in certain tumors have been targeted with agents such as C225 (Cetuximab) and ZD 1839 (IRESSA); an adenosine deaminase analogue of deoxyadenosine, Cladribine (2-chloro-2 deoxy-adenosine) has shown high effectiveness in hairy-cell leukemia and the multitargeted antifolate (Premetrexed) and several vaccines have been studied and are in clinical trials for resistant cancers.

Addition of ADA to the co-cultures resulted in enhanced CD4(+) and CD8(+) T-cell proliferation and robust ADA-induced increase in cytokine production (IFN-gamma, TNF-alpha and IL-6).

As IFN-gamma, TNF-alpha and IL-6 promote the Th1 versus Th2 phenotype and improve T helper proliferation responses and antigen-specific CTL responses ADA may be considered a promising candidate for therapeutic vaccine adjuvant.

Adenosine deaminase acting on RNA 1 (ADAR1) suppresses the induction of interferon by measles virus.
|
12 |
22278222
|
ADAR1, the interferon (IFN)-inducible adenosine deaminase acting on RNA, catalyzes the C-6 deamination of adenosine (A) to produce inosine (I) in RNA substrates with a double-stranded character.
|

|
Because double-stranded RNA is a known inducer of IFN, we tested the role of ADAR1 in IFN induction following virus infection.

|
HeLa cells made stably deficient in ADAR1 (ADAR1(kd)) were compared to vector control (CON(kd)) and protein kinase PKR-deficient (PKR(kd)) cells for IFN-β induction following infection with either parental (wild-type [WT]) recombinant Moraten vaccine strain measles virus (MV) or isogenic knockout mutants deficient for either V (V(ko)) or C (C(ko)) protein expression.
|

|
We observed potent IFN-β transcript induction in ADAR1(kd) cells by all three viruses; in contrast, in ADAR1-sufficient CON(kd) cells, only the C(ko) mutant virus was an effective inducer and the IFN-β RNA induction was amplified by PKR.
|
16 |
22278222
|
The enhanced IFN-β transcript-inducing capacity of the WT and V(ko) viruses seen in ADAR1-deficient cells correlated with the enhanced activation of PKR, IFN regulatory factor IRF3, and activator of transcription ATF2, reaching levels similar to those seen in C(ko) virus-infected cells.
|

|
These results suggest that ADAR1 functions as an important suppressor of MV-mediated responses, including the activation of PKR and IRF3 and the induction of IFN-β RNA.
|
18 |

|
Our findings further implicate a balanced interplay between PKR and ADAR1 in modulating IFN-β protein production following virus infection.

In autologous cocultures of T cells with HIV-1-pulsed dendritic cells, addition of adenosine deaminase led to a significant decrease of HIV-1-induced CD4(+)CD25(hi) forkhead box p3(+) cells and to a significant enhancement of the HIV-1-specific CD4(+) responder T cells.

An increase in the effector response was confirmed by the enhanced production of CD4(+) and CD8(+) CD25(-)CD45RO(+) memory cell generation and secretion of Th1 cytokines, including IFN-γ and IL-15 and chemokines MIP-1α/CCL3, MIP-1β/CCL4, and RANTES/CCL5.
