Abstract
Dose-dependent interferonogenic activity and pharmacokinetics of cycloferon--a low-molecular inductor of interferon--have been studied in a group of 35 healthy volunteers. It is established that cycloferon induces the production of early alpha-IFN within 24 h from the moment of drug introduction. In a dose of 500 mg, the drug induces production of gamma-IFN by leukocytes in vitro within 24 h from the moment of introduction, with retention of the titer for 48 h. This proves the need for differentiated approach to a choice of the dose of cycloferon, depending on diseases in which complex treatment involving interferon inductors is required. After the introduction of cycloferon (500 mg) in healthy volunteers, the peak of drug concentration in the blood is observed in 40 min, with the subsequent considerable decrease within 2 h. Variation of the cycloferon concentration in the blood correlates with its content in urine, which is evidence for the drug elimination from organism through kidneys.

Abstract
Clinicopathogenetic impact of cycloferon, an endogenous interferon inductor, on the process of Astrakhan rikettsial fever, its complications and outcomes was analysed. The treatment scheme with addition of cycloferon to the complex therapy was optimized. The specificity of the disease clinical process and the level of the interferon status in the patients treated with cycloferon alone or with combination of the standard therapy and cycloferon was shown. It was observed that in the patients with moderate severity of the disease the combined use of the standard therapy and cycloferon was in favour of arresting the disease clinical signs (fever, headache, weakness, eruption, hepatomegaly, arthralgia and myalgia, lymphatic gland inflammation, primary affect) and lowered the hospitalization term vs. the standard therapy alone. In the patients with moderate severity of the disease the levels of the serous interferon-alpha before the treatment were found lower, while those of interferon-gamma were higher. The use of cycloferon in the treatment scheme resulted in increase of the interferon-alpha levels and decrease of the higher levels of interferon-gamma. The standard therapy in combination with cycloferon in the patients with moderate severity of the disease provided changes in the immune status: increase of the relative content of T- and B-lymphocytes and normalization of their absolute number. Normalization of the phagocytic activity and the coefficient of the active phagocytes, as well as increase of the phagocytic index, the levels of immunoglobulins G, A and M and the number of the circulating immune cells were stated. The standard therapy with addition of cycloferon resulted in normalization of the levels not only of succinic denydrogenase, lactate dehydrogenase and glucose-6-dehydrogenase but also of alpha-naphthylacetate esterase and alpha-naphthylbutirate esterase in the neutrophils, as well as of the whole spectrum of the monocyte enzymes, except NAD-diaphorase. The adverse reactions were observed in 2.5% of the cases (9 subjects). All of them were mild and did not require discontinuation of the drugs use.

Abstract
In recent years, both interferons and inductors of endogenous interferon production find increasing use in clinical practice. The latter agents are characterized by high antiviral and immunomodulatory activity in the absence of serious side effects, which makes it possible to prescribe long courses if necessary. One of the most frequently used interferon inductors is cycloferon. Diverse effects of cycloferon on biochemical and cellular cascades (including induction of alpha- and beta-interferon, inhibition ofproapoptotic factors such as tumor necrosis factor and interleukin 1-beta) suggest that it also takes active part in the regulation of apoptosis, one of the most important processes of cell activity that opens up new prospects for the therapeutic use of cycloferon.

Abstract
OBJECTIVE UBE2L3 is associated with susceptibility to systemic lupus erythematosus (SLE) and rheumatoid arthritis in European ancestry populations, and this locus has not been investigated fully in non-European populations. We studied the UBE2L3 risk allele for association with SLE, interferon-α (IFN-α), and autoantibodies in a predominantly African American SLE cohort. METHODS We studied 395 patients with SLE and 344 controls. The UBE2L3 rs5754217 polymorphism was genotyped using Taqman primer-probe sets, and IFN-α was measured using a reporter cell assay. RESULTS The UBE2L3 rs5754217 T allele was strongly enriched in African American patients with anti-La antibodies as compared to controls, and a recessive model was the best fit for this association (OR 2.55, p = 0.0061). Serum IFN-α also demonstrated a recessive association with the rs5754217 genotype in African American patients, and the TT/anti-La-positive patients formed a significantly high IFN-α subgroup (p = 0.0040). Similar nonstatistically significant patterns of association were observed in the European American patients with SLE. Case-control analysis did not show large allele frequency differences, supporting the idea that this allele is most strongly associated with anti-La-positive patients. CONCLUSION This pattern of recessive influence within a subgroup of patients may explain why this allele does not produce a strong signal in standard case-control studies, and subphenotypes should be included in future studies of UBE2L3. The interaction we observed between UBE2L3 genotype and autoantibodies upon serum IFN-α suggests a biological role for this locus in patients with SLE in vivo.

Abstract
AIM Study dynamics of IFNalpha, IFNgamma, TNFalpha cytokines in healthy adults after administration of inactivated subunit monovalent influenza vaccine, A/California/7/2009 (H1N1) strain. MATERIALS AND METHODS Levels of IFNalpha, IFNgamma, TNFalpha cytokines were studied in blood sera of 58 mostly healthy adults aged 18 - 60 years. Kits for enzyme immunoassay determination of cytokine levels (Vector-Best, Novosibirsk) were used in the study. Antibody titers to A/California/7/2009 (H1N1) strain were determined at analogous time by using microneutralization reaction (MNR). RESULTS Changes in the level of IFNalpha, IFNgamma, TNFalpha in healthy volunteers immunized by pandemic influenza vaccine were evaluated. Vaccine was safe. Two immunizations did not result in an increase of TNFalpha level that is an additional evidence of vaccine safety. IFNalpha level had a tendency to increase in vaccinated volunteers. IFNgamma levels in volunteers with normal level of this cytokine (below 10 pg/ml) were increased significantly after the second immunization (from 2.66 +/- 2.48 to 5.21 +/- 2.56). Correlation analysis showed that there is a strong negative association between IFNalpha, IFNgamma and seroconversion.

Abstract
Cytomegalovirus (CMV) infection is a wide-spread disease throw humans and monkeys, which and associated with various diseases. The development of this infection in human organism is much like that in rhesus macaque, which makes CMV-infected monkeys adequate model for studying and elaborating prophylactic and therapeutic measures against this disease in humans. This article presents data on the efficiency of cycloferon action on animals with the M. mulatta CMV infection. Cycloferon stimulated an increase in the IFN-alpha production and promoted the period of remission in CMV-infected animals.

Abstract
New factors that influence the viral response in HCV non-genotype 2/3 patients must be identified in order to optimize anti-HCV treatment. This multicenter prospective study evaluates the influence of HCV variability and pharmacological parameters on the virological response of these patients to pegylated interferon α2a (peg-IFN-α2a: 180 µg/week) and ribavirin (RBV; 800-1,200 mg/day) for 48 weeks. HCV subtypes were identified by sequencing the NS5B region. Serum RBV and peg-IFN-α2a concentrations were measured at weeks 4 and 12. The 115 patients (67 men; median age = 49, range 31-76) included 64 who had never been treated and 27 co-infected with HIV. The mean baseline HCV RNA was 6.30 ± 0.06 log IU/ml and the HCV genotypes were: G1 (n = 93) with 1a (n = 37) and 1b (n = 50), G4 (n = 20) and G5 (n = 2). Most patients (79/108; 73%) had an early virological response. Independent predictors of an early virological response were interferon naive patients (OR= 2.98, 95% CI: 1.15-7.72) and RBV of >2,200 ng/ml at week 12 (OR = 3.41, 95% CI: 1.31-8.90). Forty of 104 patients (38%) had a sustained virological response. The only independent predictors of a sustained virological response were subtype 1b (OR = 6.82, 95% CI: 1.7-26.8), and HCV RNA <15 IU/ml at week 12 (OR = 25, 95% CI: 6.4-97.6). Thus a serum RBV concentration of >2,200 ng/ml was associated with an early virological response and patients infected with HCV subtype 1b had a better chance of a sustained virological response than did those infected with subtype 1a.

Abstract
CONTEXT Graves' disease (GD) is a common autoimmune disease that affects the thyroid gland. Its pathogenesis is tightly involved with aberrant proinflammatory cytokine production. Osteopontin (OPN), an extracellular matrix protein of pleiotropic properties, has recently been recognized as a potent inflammatory cytokine in several autoimmune diseases. OBJECTIVE This study sought to explore the pathophysiological role of OPN in GD by comparing OPN levels in initial GD patients and healthy controls. METHODS Seventy-six patients who met criteria for initial GD and sixty-five healthy controls were recruited. OPN and other clinical GD diagnosis parameters were measured. In addition, the coexpression of several OPN receptors as well as various nuclear factor-κB (NF-κB) downstream target genes were examined in peripheral blood mononuclear cells from human subjects. The effect of OPN on NF-κB activation was determined by in vitro assays. RESULTS We demonstrated for the first time that the OPN levels are enhanced in serum from GD patients. OPN levels are strongly associated with clinical serum parameters for GD diagnosis. The coexpression of selective OPN receptors and inflammatory response genes was enhanced in peripheral blood mononuclear cells from GD patients. Furthermore, serum from GD patients activated NF-κB activity in vitro, which was significantly suppressed by OPN monoclonal antibody abrogation. CONCLUSION These data indicated a clinical correlation between serum OPN levels and GD. OPN could affect GD development through NF-κB activation and the subsequent changes in inflammatory milieu. OPN could serve as a novel biomarker for GD as well as a potential target for GD treatment.

Abstract
OBJECTIVES Vitamin D deficiency is widespread and has been associated with many chronic diseases, including autoimmune disorders. A study was undertaken to explore the impact of low vitamin D levels on autoantibody production in healthy individuals, as well as B cell hyperactivity and interferon α (IFNα) activity in patients with systemic lupus erythematosus (SLE). METHODS Serum samples from 32 European American female patients with SLE and 32 matched controls were tested for 25-hydroxyvitamin D (25(OH)D) levels, lupus-associated autoantibodies and serum IFNα activity. Isolated peripheral blood mononuclear cells were tested for intracellular phospho-ERK 1/2 as a measure of B cell activation status. RESULTS Vitamin D deficiency (25(OH)D <20 ng/ml) was significantly more frequent among patients with SLE (n=32, 69%) and antinuclear antibody (ANA)-positive controls (n=14, 71%) compared with ANA-negative controls (n=18, 22%) (OR 7.7, 95% CI 2.0 to 29.4, p=0.003 and OR 8.8, 95% CI 1.8 to 43.6, p=0.011, respectively). Patients with high B cell activation had lower mean (SD) 25(OH)D levels than patients with low B cell activation (17.2 (5.1) vs 24.2 (3.9) ng/ml; p=0.009). Patients with vitamin D deficiency also had higher mean (SD) serum IFNα activity than patients without vitamin D deficiency (3.5 (6.6) vs 0.3 (0.3); p=0.02). CONCLUSIONS The observation that ANA-positive healthy controls are significantly more likely to be deficient in vitamin D than ANA-negative healthy controls, together with the finding that vitamin D deficiency is associated with certain immune abnormalities in SLE, suggests that vitamin D plays an important role in autoantibody production and SLE pathogenesis.

Abstract
BACKGROUND It has been shown that dendritic cells (DCs) and fractalkine play a role in accelerating progression of the inflamed atherosclerotic lesions and plaque rupture. We evaluated the numbers and functional changes of DCs and its subsets in human type 2 diabetes with or without unstable angina pectoris (UAP). METHODS The study population consisted of 39 diabetic patients (DM:18 without CAD; DM + UAP: 21 with UAP), 18 non-diabetic UAP patients (UAP), and 15 healthy control (Normal). Peripheral blood DCs and its subsets were measured by three color flow cytometry. Serum levels of fractalkine, IL-12, and IFN-α were also measured. The functional status of the monocyte-derived DCs was analyzed by flow cytometry and allogeneic mixed T lymphocytes reaction. RESULTS The percent and absolute numbers of DCs and mDC within the total leukocyte population was similar for Normal and DM, while significantly lower in DM + UAP. pDC numbers were not significantly altered. Serum fractalkine in DM + UAP was highest among the four groups (p = 0.04 vs. UAP, p = 0.0003 vs. DM, p < 0.0001 vs. Normal). Circulating mDC inversely correlated with serum fractalkine (r = -0.268, p = 0.01) level. Compared with DM and UAP, the costimulatory molecules CD86 and proliferation of T cells stimulated by DCs were significantly increased in DM + UAP group. CONCLUSIONS Our study suggested that increases in the fractalkine level and the number and functional changes of blood DCs might contribute to diabetic coronary atherosclerosis and plaque destabilization.

Abstract
The aim of the study was to investigate serum levels, as well as the ability to produce in vitro, some pro-inflammatory and anti-inflammatory cytokines in patients with brain tumours (BT). Serum concentrations of IFN-gamma, IFN-alpha, TNF-alpha, IL-4, IL-6, IL-8, and RA IL-1 were determined in 17 patients with brain tumours, and in 21 healthy donors. The results showed that baseline levels of cytokines studied was above normal in most patients (78%) had the highest rates of IFN-gamma. During the whole observation period, slightly higher in patients compared with healthy individuals (t=1.8) was the content of IFN-alpha. Serum concentrations of IL-4 in patients before treatment were significantly higher than in control group (p<0.01), remaining at about the same level, and after treatment. Levels of Rail-1, IL-6 and IL-8 in patients before treatment were within normal limits, while remaining unchanged at the end of the survey. Indicators induced in vitro production of cytokines studied to some extent correlated with their serum levels. Hyperproduction in vitro IFN-gamma was observed in 61% of patients, low production - 28% of patients, and only in 11% of cases, these figures were within normal limits. In patients with malignant brain tumors were identified violations of serum levels and production of cytokines studied. The most significant was the increase of PHA-induced production of IFN-gamma, which was not reduced by the end of treatment. High serum and, in particular, PHA-induced levels of IFN-gamma at the end of treatment may be recommended as an additional criterion for immunodiagnosis in a dynamic laboratory monitoring.

Abstract
Features of the immune response of children with chronic hepatitis C to the antiviral and pathogenetic therapy have been studied. It is shown that the antiviral therapy is accompanied by stimulation of the immune response as manifested by the synthesis of cytokines (IL-4, IFN-alpha, IFN-gamma) with retention of increased production of IFN-a for more than two years after the end of the course of treatment. In children that previously received interferon inductor (cycloferon) for 12 months, high level of IFN-a production is retained, which ensures antiviral protection. Phytotherapy did not influence the production of cytokines.

Abstract
Recent studies indicate that high-mobility group box protein 1 (HMGB1) contributes to the pathogenesis of diverse autoimmune disorders. It induces the production of interferon-alpha (IFN-alpha) and tumor necrosis factor alpha (TNF-alpha) in vitro. In the present study, plasma HMGB1, TNF-alpha, and IFN-alpha were determined with ELISA in 37 patients with systemic lupus erythematosus (SLE) and 39 age- and sex-matched healthy controls (HC). The possible associations of these cytokines with disease activities, autoantibodies, and certain laboratory parameters were also explored. The plasma levels of HMGB1, TNF-alpha, and IFN-alpha were increased in SLE patients compared with those of HC (P < 0.05). Moreover, the levels of HMGB1 and TNF-alpha in the active SLE patients were elevated compared with those in inactive patients and HC. Additionally, plasma HMGB1 was positively correlated with peripheral neutrophils, and plasma TNF-alpha was positively correlated with anti-Sm, ESR and CRP, while plasma IFN-alpha was inversely correlated with the age and platelet level in SLE patients. Our data indicated that increased plasma HMGB1 was associated with disease activity in SLE, which was similar to TNF-alpha. High level of plasma IFN-alpha may be related to nephritis and thrombocytopenia in SLE.

Abstract
We compared efficacy of combined treatment of males with anogenital warts given intramuscular cycloferon or cycloferon electrophoresis. Patients with manifest HPV infection (n=107) were divided into two groups. Group 1 (n=72) received intramuscular cycloferon (2 ml 12.5% solution each other day for 10 days), group 2 (n=35) received cycloferon electrophoresis on genital region (2 ml 12.5% solution daily in 1-2 days, 5 injections). Measurements were made of local cytokines in urethral secretion, IFN-alpha, IFN-gamma, lactoferrin, sexual hormones (estradiol and testosterone) in blood serum before and after treatment. Focal immunophysiotherapy with cycloferon in combined treatment of males with anogenital warts vs intramuscular cycloferon treatment reduces recurrence rate 2 times, has no negative effect on serum level of sexual hormones, a course dose and duration of immunotherapy decreased 2-fold, is well tolerated, is not painful. Cycloferon electrophoresis has a more potent effect on improvement of local immunity. Thus, local immunophysiotherapy with cycloferon can be a method of choice in the treatment of manifest HPV infection in males.

Abstract
A total of 40 patients with non-gonococcal urethritis (NGU) were divided into two groups. Twenty patients of group 1 received standard antibacterial treatment while 20 patients of group 2 received the same treatment plus an immunotropic drug based on tiloron (lavomax) in a course dose 1.25 g. Patients of group 2 had no recurrences while in group 1 recurrences were seen in 25% patients. Addition of lavomax resulted in clinical and etiological cure and activation of local (secretory IgA) and systemic (interferons alpha and gamma in blood serum) factors in anti-infection defense in NGU patients.

Abstract
Recombinant human interferons (rhIFNs) are broadly used as effective therapeutic agents with antiviral, antitumor, and immune-modulating properties. Advances in protein biochip technology have benefited the medical community greatly, making true parallelism, miniaturization, and high throughput possible. In this study, 5 rhIFN proteins (IFN-alpha1b, IFN-alpha2a, IFN-alpha2b, IFN-beta, and IFN-gamma) were immobilized onto an N-hydroxysuccinimide (NHS)-modified gold-based biochip. The protein biochip was incubated with 6 specific mouse IgG antibodies (AK1, AK2, AK3, AK4, BK1, and CK1) against the human IFNs and then with Cy3-conjugated goat anti-mouse IgG antibody. The results showed that monoclonal antibody AK1 presented a unique binding characteristic to IFN-alpha1b. AK2 reacted in immunoassays equally with IFN-alpha2a and IFN-alpha2b. AK3 detected IFN-alpha1b, IFN-alpha2a, and IFN-alpha2b. AK4 had positive immunological responses directed to both IFN-alpha1b and IFN-alpha2b. Monoclonal antibodies BK1 and CK1 recognized epitope of IFN-beta and IFN-gamma, specifically. The assay specificity of the biochip was further confirmed by enzyme-linked immunosorbent assay (ELISA) and western blotting. Finally, 88 serum samples from patients treated with rhIFN-alpha2b were simultaneously tested on a single biochip. The result demonstrated that 6.8% (6 of 88 cases) presented positive reactions to anti-IFN-alpha2b antibodies, indicating that the patients under rhIFN-alpha2b therapy produced neutralized antibody against the IFN. The biochip format would offer a competitive alternative tool not only for facilitating characterization of IFN subtypes but also potentially for enabling clinical serum detection of corresponding antibodies directed against IFNs.

Abstract
Type I interferon (IFN) protein is a cytokine with pleiotropic biological functions that include induction of apoptosis, inhibition of angiogenesis, and immunomodulation. We have demonstrated that intratumoral injection of an IFN-alpha-expressing adenovirus effectively induces cell death of cancer cells and elicits a systemic tumor-specific immunity in several animal models. On the other hand, reports demonstrated that an elevation of IFN in the serum following an intramuscular delivery of a vector is able to activate antitumor immunity. In this study, we compared the intratumoral and systemic routes of IFN gene transfer with regard to the effect and safety of the treatment. Intratumoral injection of an IFN-alpha adenovirus effectively activated tumor-responsive lymphocytes and caused tumor suppression not only in the gene-transduced tumors but also in distant tumors, which was more effective than the intravenous administration of the same vector. The expression of co-stimulatory molecules on CD11c(+) cells isolated from regional lymph nodes was enhanced by IFN gene transfer into the tumors. Systemic toxicity such as an elevation of hepatic enzymes was much lower in mice treated by intratumoral gene transfer than in those treated by systemic gene transfer. Our data suggest that the intratumoral route of the IFN vector is superior to intravenous administration, due to the effective induction of antitumor immunity and the lower toxicity.

Abstract
AIM Assessment of therapeutic effect and immunologic parameters during use of Immunovac vaccine for complex treatment of chronic forms of pyoderma. MATERIALS AND METHODS Ninety-five patients with different clinical forms of chronic pyoderma (furunculosis, hydradenitis, chronic ulcerative and ulcerative-vegetans pyoderma, folliculitis, impetigo etc.) were studied. Fifty-nine patients received immunotherapy with Immunovac vaccine together with basic therapy and 36 patients comprised control group treated only with basic therapy. Studied immunologic parameters were as follows: assessment of functional activity of lymphocytes, determination of lymphocyte subpopulations by flow cytometry, total immunoglobulins classes A, G, M by radial immunoduffusion, affinity of antibodies by enzyme immunoassay, levels of IFNalpha and IFNgamma. RESULTS Use of Immunovac vaccine in complex treatment of patients with chronic forms of pyoderma enhanced clinical effect of basic therapy, which expressed in decrease of severity and frequency of disease relapses irrespective to clinical form and severity of pyoderma. Therapeutic effect during use of Immunovac vaccine amounted 84.7%, whereas in control group it was 41.6% after 12 months of follow-up. Increase of functional activity of neutrophils, subpopulation of lymphocytes with markers CD4+, CD8+, CD72+, affinity of antibodies as well as induced production of IFNalpha and IFNgamma was revealed. Correction of immunologic parameters correlated with positive results of patients treatment. CONCLUSION Inclusion of bacterial polycomponent vaccine Immunovac in complex treatment of patients with chronic pyoderma promotes enhancement of therapeutic effect of basic therapy and correction of immunologic parameters.

Abstract
The authors have determined blood parameters reflected condition of the non-specific immunologically-mediated resistance (NIR) in workers of the oil industry, including persons directly participated in oil wells exploration and exposed for long period of time to low doses of ionizing radiation. The article presents obtained results of the percentage of neutrophils and natural killer cells as well as the level of alpha-interferon in the blood serum. Obtained results demonstrated that parameters of NIR of oil industry workers were not substantively different from analogous parameters of healthy person living in the same region.

Abstract
Allergic contact dermatitis to cement is a delayed-type hypersensitivity reaction in which cytokines interferon-gamma (IEN-y) and vascular endothelial growth factor(VEGF) may be involved in persisting erythema and oedema. VEGF and IFN-gamma levels in serum and skin lesions were measured in 32 Egyptian building workers with chronic allergic contact dermatitis due to occupational exposure to cement and 20 healthy controls. Dermatitis patients had significantly higher levels of serum and lesional skin VEGF and IFN-gamma than controls. A significant positive correlation was found between tissue VEGF and the eczema area and severity index (EASI) score in dermatitis patients (r = 0.86). VEGF and IFN-gamma may play a role in the pathogenesis of cement allergic contact dermatitis.

Abstract
The study of changes in the immune status of patients with chronic bacterial prostatitis demonstrated changes in immunological parameters reflecting depression of the immune system (subnormal levels of interferon alpha, gamma, sIgA, functional activity of neutrophils, high concentration of IgA, IgG, IgM). Thus, combined treatment of chronic bacterial prostatitis must include administration of immunomodulators.

Abstract
Vaccines currently licensed for the prevention of seasonal influenza induce antibodies against the influenza hemagglutinin (HA) and neuraminidase (NA) contained in the vaccine preparation but require at least 2 weeks after immunization for the development of protective immunity. These vaccines do not induce protective responses quickly enough to blunt the effects of infection when administered after exposure. We have developed a novel vaccine based on recombinant vesicular stomatitis virus which expresses the influenza hemagglutinin (rVSV HA) and protects mice from lethal influenza challenge when the vaccine is administered intramuscularly at least 24h after delivery of the influenza challenge virus. To our knowledge this is the first vaccine that effectively protects animals from lethal influenza challenge when delivered by a systemic route after influenza exposure has occurred. The induction of HA-specific immune responses by the vaccine is necessary for full protection from challenge, because animals immunized with an empty rVSV vector were not protected equally. Our results are consistent with a model in which vaccination induces an immediate antiviral cytokine response, followed by development of humoral and cellular immune responses which act to reduce pulmonary viral loads and accelerate recovery. Consistent with this model, mice vaccinated with the specific vaccine rVSV HA had high levels of IFN-alpha in the serum by 24h after challenge/vaccination, developed serum neutralizing Ab to influenza 2 days prior to control animals, and had detectable anti-HA CD8 T cells present in the peripheral blood 3 days prior to control mice.

Abstract
The type I interferons (IFNs) have antiviral, cytostatic and prominent immunomodulatory effects, which all are of great importance during viral infections. However, prolonged exposure of the immune system to type I IFN can break tolerance and initiate an autoimmune reaction, eventually leading to autoimmune disease. Recent observations in patients with systemic lupus erythematosus (SLE) have revealed that such individuals have endogenous IFN-alpha inducers, causing an ongoing IFN-alpha production and consequently a continuous stimulation of the immune system. These IFN-alpha inducers consist of small immune complexes (IC) containing DNA or RNA and act on the principal IFN-alpha producing cell, the natural IFN-alpha producing cell (NIPC), also termed the plasmacytoid dendritic cell (PDC). The NIPC/PDC is a key cell in both the innate and adaptive immune response but can also, either directly or via produced IFN-alpha, have a pivotal role in autoimmunity. In this review we summarize recent data concerning NIPC/PDC, including their activation, regulation, function and possible role in autoimmune diseases, especially SLE.

Abstract
In this study, pigs were injected with a nonreplicating human adenovirus type 5 vector expressing porcine interferon-alpha (Ad5-pIFN-alpha) and then challenged with porcine reproductive and respiratory syndrome virus (PRRSV) to determine whether the presence of increased levels of IFN-alpha would decrease viral replication and/or disease. Groups of 10 pigs each were inoculated with Ad5-pIFN-alpha and not challenged, Ad5-pIFN-alpha and challenged with PRRSV 1 d later, or inoculated with a control adenovirus that does not express IFN-alpha (Ad5-null) and challenged 1 d later with PRRSV. IFN-alpha levels in all pigs inoculated with the Ad5-pIFN-alpha were elevated the day of challenge (1 d after inoculation), but were undetectable by 3 d after inoculation in the pigs that were not challenged with PRRSV. Pigs inoculated with Ad5-pIFN-alpha and challenged with PRRSV had lower febrile responses, a decreased percentage of lung involvement at 10 d post-infection, delayed viremia and antibody response, and higher serum IFN-alpha levels as a result of PRRSV infection, compared to pigs inoculated with Ad5-null and challenged with PRRSV. These results indicate that IFN-alpha can have protective effects if present during the time of infection with PRRSV.
