Abstract
Psoriatic arthritis (PsA) is a chronic inflammatory condition characterized by psoriasis, synovitis, enthesitis, spondylitis, and the possible association with other extra-articular manifestations and comorbidities. It is a multifaceted and systemic disorder sustained by complex pathogenesis, combining aspects of autoinflammation and autoimmunity. Features of PsA autoinflammation include the role of biomechanical stress in the onset and/or exacerbation of the disease; the evidence of involvement of the innate immune response mediators in the skin, peripheral blood and synovial tissue; an equal gender distribution; the clinical course which may encounter periods of prolonged remission and overlapping features with autoinflammatory syndromes. Conversely, the role of autoimmunity is evoked by the association with class I major histocompatibility complex alleles, the polyarticular pattern of the disease which sometimes resembles rheumatoid arthritis and the presence of serum autoantibodies. Genetics also provide important insights into the pathogenesis of PsA, particularly related to class I HLA being associated with psoriasis and PsA. In this review, we provide a comprehensive review of the pathogenesis, genetics and clinical features of PsA that endorse the mixed nature of a disorder at the crossroads of autoinflammation and autoimmunity.

Abstract
OBJECTIVE Most lupus patients produce autoantibodies against small ribonucleoproteins such as Sm/RNP and Ro 60 (containing U1 and Y1-Y5 RNAs, respectively). We undertook this study to investigate whether the RNA components of these antigens, which contain extensive tracts of single- and double-stranded RNA, signatures of viral infection, activate innate immunity. METHODS U1 and Y RNAs were affinity purified from K562 cells. Murine bone marrow-derived dendritic cells (DCs), human HEK 293 cells, and murine RAW264.7 cells were stimulated with U1 RNA and other known Toll-like receptor (TLR) ligands. Expression of the interferon (IFN)-inducible gene Mx1 and other genes was quantified using real-time polymerase chain reaction, and cytokine production was measured by enzyme-linked immunosorbent assay. DC maturation was assessed using flow cytometry. RESULTS Purified U1 and Y1-Y5 RNAs and synthetic stem-loop II of U1 RNA stimulated type I IFN (IFN-I) production by cell lines and murine bone marrow-derived DCs and promoted DC maturation (CD86 expression). U1 RNA-stimulated, but not TLR-3 ligand-stimulated, IFN-I was blocked by bafilomycin A1, indicating that immunostimulation by U1 RNA requires endosomal acidification. Myeloid differentiation factor 88-deficient cells responded poorly to U1 RNA, suggesting that an endosomal TLR, probably TLR-7, mediates the stimulatory effects of U1 RNA. U1 RNA-induced IFN-I and interleukin-6 production also were protein kinase R (PKR) dependent (abrogated by 2-aminopurine and greatly reduced in PKR-/- cells). CONCLUSION We conclude that the RNA components of the Ro 60 (Y1-Y5 RNA) and Sm/RNP (U1 RNA) small ribonucleoproteins act as endogenous adjuvants that could play a role in the pathogenesis of autoimmunity by stimulating DC maturation and IFN-I production.

Abstract
OBJECTIVE To determine a target recognized by anti-Bh autoantibody, found in the serum of a patient with the unusual coexistence of systemic sclerosis (SSc) and psoriatic arthritis (PsA). METHODS Antigens recognized by the anti-Bh serum were characterized by indirect immunofluorescence on HeLa cells, by conventional immunoblotting using nuclear extract or partially purified preparation of heterogenous nuclear RNP (hnRNP) proteins, and by 2-dimensional immunoblotting. For the analysis of cross-reactivity and immunofluorescence patterns, autoantibodies were affinity-purified by blot elution and then retested. RESULTS Comparison of the reactivity of the anti-Bh antibody with the monoclonal antibody 4F4 against both the hnRNP C proteins, together with the determination of biochemical properties of the autoantigens, led to the identification of C1 and C2 core proteins as the targets for the anti-Bh autoantibody. CONCLUSION Several essential components of the spliceosome are targeted by autoantibodies that are present in the sera of patients with systemic rheumatic diseases. We also found that the hnRNP core proteins C1 and C2 are recognized by the autoantibody present in the serum of a patient with SSc and PsA. C1 and C2 hnRNP proteins should be added to the several intracellular autoantigens recently shown to be cleaved by interleukin-1beta-converting enzyme-like enzymes during apoptosis.

Abstract
Autoantibodies to Su and anti-nRNP/Sm are common in human and murine systemic lupus erythematosus (SLE), and are also produced by BALB/c mice with SLE-like autoimmunity induced by pristane. Antigen capture ELISAs employing monospecific human autoimmune IgG were developed to quantitate the production of anti-Su and anti-nRNP/Sm autoantibodies in 77 sera from BALB/c mice with pristane-induced autoimmunity. The sensitivity and specificity of the anti-Su antigen capture ELISA were 100% compared with immunoprecipitation of 35S-labeled cellular proteins. All 16 immunoprecipitation positive sera were positive in the anti-nRNP/Sm antigen capture ELISA (100% sensitivity), whereas 55/61 immunoprecipitation negative sera were negative by ELISA (90% specificity). The 6/61 immunoprecipitation negative sera that were ELISA positive were probably true positives because subsequent sera obtained from the same mice were positive by both techniques. Thus, the antigen capture ELISA may be somewhat more sensitive than immunoprecipitation. The titers of anti-Su and anti-nRNP/Sm positive antibodies in the sera were as high as 1:25,000-1:250,000 by ELISA, suggesting that autoantibodies may be produced in pristane-primed BALB/c mice at levels comparable to those seen in spontaneous autoimmune disease. We conclude that antigen capture ELISAs based on human autoimmune sera were highly sensitive and specific for detecting murine anti-Su and anti-nRNP/Sm antibodies. This technique will be useful for quantitating antibodies in murine autoimmune disease models, since antigen capture ELISA avoids the use of denatured or recombinant antigens, permitting antibodies recognizing tertiary and quaternary structures to be detected.

Abstract
This is a single case report of a 56-year-old Caucasian female referred for biofeedback by her dermatologist after seven years of failed standard medical treatment for psoriasis. Patient's presenting complaint was the embarrassing psoriasis lesions on her arms. Following 13 weekly one-hour finger/hand thermal biofeedback treatments, all 11 presenting psoriasis lesions (2-6 cm) had disappeared. Interestingly, any new psoriasis lesions that surfaced during our treatment disappeared without leaving palpable or visible scarring, unlike lesions that were present prior to biofeedback treatment. Patient was unmedicated for psoriasis during our treatment and continues to be unmedicated and asymptomatic at 12-month follow-up.

Abstract
Autoantibodies to RNA polymerases (RNAP) I, II, and III are reported to be highly specific for the diagnosis of scleroderma (systemic sclerosis, SSc). In the present study, the specificity of autoantibodies to RNAP I and III for SSc was confirmed by immunoprecipitation of 35S-labeled proteins. However, we report here the previously unrecognized production of anti-RNAP II autoantibodies by 9-14% of patients with SLE and mixed connective tissue disease/overlap syndrome. 12 out of 32 anti-RNAP II positive sera (group 1) immunoprecipitated a diffuse 220-240-kD band identified as the largest subunit of RNAP II whereas the remaining 20 (group 2) immunoprecipitated preferentially the 240-kD phosphorylated (IIo) form of the large subunit. After pulse labeling, group 1 sera immunoprecipitated only the 220-kD (IIa) RNAP II subunit, whereas the diffuse IIa/IIo band plus the 145-kD second largest RNAP II subunit (IIc) were immunoprecipitated after several hours of cold chase, suggesting that these sera recognized primarily the largest subunit of RNAP II. Group 2 sera recognized the IIc subunit after pulse labeling, and immunoprecipitated the IIc and IIo, but not the IIa, subunits after cold chase. Although it has been suggested that autoantibodies to RNAP II are usually accompanied by anti-RNAP I/III in SSc, all but one of the anti-RNAP II positive sera from SLE or mixed connective tissue disease/overlap syndrome patients, as well as most of the SSc sera, were negative for anti-RNAP I/III. Moreover, in contrast to previous reports suggesting that anti-RNAP antibodies rarely coexist with other SSc subset marker antibodies, anti-RNAP II antibodies were often accompanied by anti-Ku, anti-nRNP, or anti-topoisomerase I autoantibodies in the present study. We conclude that autoantibodies to RNAP II are not a specific marker for SSc, whereas autoantibodies to RNAP I/III are associated primarily with SSc. In addition, we have identified two distinctive patterns of RNAP II antigen recognition by autoantibodies, one of them characterized by specific recognition of the transcriptionally active (phosphorylated) form of RNAP II. The clinical significance of these different patterns remains to be determined.

Abstract
All interferons display antiviral properties, but gamma-interferon especially has an immunomodulatory effect and may induce autoimmune phenomena. Therefore the formation of autoantibodies was investigated in patients with chronic hepatitis B treated with gamma-interferon. Eleven patients (all HBs-Ag and HBe-Ag positive) were treated for 6 months with recombinant gamma-interferon. The following antibodies were tested: anti-nuclear antibodies, smooth muscle antibodies, anti-actin, anti-mitochondrial antibodies of subgroup anti-M2 and anti-M9 as well as naturally occurring antibodies, antibodies to liver-kidney microsomes, vascular endothelial cell antibodies, sarcolemmal antibodies, parietal cell antibodies, thyroglobulin antibodies and antibodies to laminin and keratin. All patients produced autoantibodies during therapy. The maximum antibody formation and the highest titres were observed in the period between the 3rd and 6th month after therapy began. The cumulative frequencies of the different antibody specificities were as follows: n = 6 anti-nuclear antibodies, n = 7 smooth muscle antibodies, n = 1 anti-actin, n = 12 antibodies to laminin or keratin, n = 6 endothelial cell antibodies/sarcolemmal antibodies, n = 6 anti-mitochondrial antibodies, n = 1 antibodies to liver-kidney microsomes, n = 2 thyroglobulin antibodies, n = 4 parietal cell antibodies. Antibodies persisted in six patients over a period of 3 months (two cases of parietal cell antibodies and one case of antibodies to liver-kidney microsomes) and were still detectable in three patients 6 months after therapy. In three patients new antibody formation occurred 1 month after therapy. So far, clinical signs of an autoimmune disorder have not appeared in any of the patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
OBJECTIVE To identify the fine specificity patterns of maternal anti-SS-A/Ro and anti-SS-B/La antibodies that are associated with the birth of a child with transient or permanent manifestations of neonatal lupus syndromes, and to suggest a predictor algorithm for use in counseling. METHODS Sera were obtained from 4 groups of mothers: 57 whose children had congenital heart block, 12 whose children had transient dermatologic or hepatic manifestations of neonatal lupus but no detectable cardiac involvement, 152 with systemic lupus erythematosus and related autoimmune diseases, who gave birth to healthy infants, and 30 with autoimmune diseases whose pregnancy resulted in miscarriage, fetal death, or early postpartum death unrelated to neonatal lupus. Antibodies to SS-A/Ro and SS-B/La were assessed by enzyme-linked immunosorbent assay (ELISA) and by sodium dodecyl sulfate (SDS)-immunoblot. RESULTS Anti-SS-A/Ro antibodies were identified by ELISA in 100%, 91%, 47%, and 43% of the mothers of infants with heart block, with transient neonatal lupus, healthy infants, and fetal death, respectively. High titers of anti-SS-A/Ro antibodies were present more often in mothers of children with cardiac disease or transient neonatal lupus than in either of the other 2 groups. Maternal antibodies to SS-B/La were detected by ELISA in 76% of the heart block group, 73% of the cutaneous neonatal lupus group, 15% of the group with healthy children, and 7% of the fetal death group. On SDS-immunoblot, sera from 91% of the heart block group mothers who had antibodies to SS-A/Ro but not to SS-B/La recognized at least 1 SS-A/Ro antigen, with significantly greater reactivity against the 52-kd component. In contrast, only 62% of the anti-SS-A/Ro positive, anti-SS-B/La negative responders in the healthy group recognized the 52-kd and/or the 60-kd component. Although there was no profile of anti-SS-A/Ro response unique to the mothers of children with heart block or cutaneous manifestations of neonatal lupus, only 1% of the healthy infants were born to mothers with antibodies directed to both the 52-kd SS-A/Ro and 48-kd SS-B/La antigens and not to the 60-kd SS-A/Ro antigen. CONCLUSION Women with antibodies to both SS-A/Ro and SS-B/La have an increased risk of giving birth to children with neonatal lupus, especially if the anti-SS-A/Ro response identifies the 52-kd component on SDS-immunoblot. Women whose sera contain only anti-SS-A/Ro antibodies in low titer and only recognize determinants that are altered by conditions of SDS-immunoblot have a low risk for giving birth to a child with neonatal lupus. Specific antibody profiles do not distinguish among the manifestations of the neonatal lupus syndromes.

Abstract
Antibody penetration of viable cells and interaction with intracellular antigens may have major consequences for immunopathological processes in connective tissue diseases. We have reported previously that antibody can penetrate viable human lymphocytes. To assess further the role of antinuclear antibodies in this process, peripheral blood lymphocytes (PBMC) were incubated with FITC-conjugated IgG fractions from sera containing anti-RNP (anti-RNP IgG), Ro(SS-A), La(SS-B) and dsDNA antibodies and control sera for 24 h. Using crystal violet to quench cell surface staining, intracellular fluorescence of viable lymphocytes was quantified on the flow cytometer. It was noted that anti-RNP IgG entered 46.4 +/- 7.2% of lymphocytes which was significantly higher than anti-Ro(SS-A) (29.9 +/- 4.1%, P less than 0.05), La(SS-B) (22.0 +/- 7.5%, P less than 0.01) IgG and control IgG (28.8 +/- 2.1%, P less than 0.05) and not statistically different from anti-dsDNA IgG (32.6 +/- 14.3%). Inhibition experiments showed that the increased number of cells penetrated by anti-RNP IgG was a specific process. Time-course studies showed that anti-RNP IgG entry into cells was different from pooled control IgG. With anti-RNP IgG, positive-staining lymphocytes gradually increased in number from 12 to 24 h incubation, whilst with pooled control IgG, the peak was reached within 5 min. Dual staining experiments suggested that whereas both anti-RNP IgG and pooled control IgG entered B and NK cells, anti-RNP IgG also entered T cells. Using IgG F(ab')2 and Fc fragments from either anti-RNP IgG or pooled control IgG to compete with their FITC-conjugated counterparts indicated that the entry of anti-RNP IgG into-viable cells appeared to involve both F(ab')2 and Fc fragments, and pooled control IgG depended exclusively on the Fc portion of IgG. Further investigation by incubating anti-RNP IgG with 35S-methionine-labelled monocyte-depleted PBMC (MD-PBMC) suggested that anti-RNP IgG might react with the corresponding antigens either on the cell surface or within the cytoplasm.

Abstract
Circulating autoantibodies against a variety of nuclear and nucleolar antigens are characteristic serologic findings in systemic scleroderma. Some of these antibodies correlate with clinical subsets of the disease. We describe three patients with systemic scleroderma and high autoantibody titers against U3 ribonucleoprotein-associated fibrillarin, a recently identified 34 kD nucleolar protein. These patients showed a progressive course with multiple organ and diffuse skin involvement with disseminated telangiectasia.

Abstract
The molecular basis of autoantibody reactivity with components of the SSA/Ro-SSB/La particle exhibited by sera of mothers of infants with severe and permanent manifestations of neonatal lupus (NLE) was investigated using immunoblotting and immunoprecipitation. The characteristics of NLE that were studied included congenital complete heart block (CCHB), second degree heart block, and hepatic fibrosis. Antibodies specific for one or more components of the SSA/Ro-SSB/La particle were found in sera from all 20 mothers of permanently affected infants. However, no antibody specific for a single peptide of this particle was common to all sera. Using tissue extracts from a human cell substrate, 80% of these sera had antibodies to one or more components of the SSA/Ro particle demonstrable by immunoblotting. The predominant antibody response in the NLE group was to the newly recognized 52-kD SSA/Ro peptide component. In contrast, antibodies to the 60-kD SSA/Ro component although present, were the least represented and not significantly increased in frequency among mothers of these infants, compared with a group of 31 mothers with autoimmune diseases such as systemic lupus erythromatosus (SLE) but who had healthy offspring. Antibodies directed to the 48-kD SSB/La antigen were demonstrated in 90% of the NLE mothers often accompanying antibodies against the 52-kD SSA/Ro component. The combination of antibodies to 48- and 52-kD structures was significantly increased in the NLE group, with an odds ratio of 35. The type of cell or tissue substrate was shown to influence detectability of antibodies. The 52-kD SSA/Ro peptide and the 48-kD SSB/La peptide were abundant in cardiac tissues from fetuses aged 18-24 wk, further supporting the possible relevance of these peptides to heart block.

Abstract
The p67 (67 kDa) and A (33 kDa) polypeptides of nRNP/Sm antigen and the B, B' (28 and 29 kda) and D (16 kDa) polypeptides of 'free' Sm antigen were isolated and used in enzyme-linked immunoadsorbent assays (ELISA) for human autoantibodies. ELISA specificity was demonstrated using monoclonal antibodies. The ELISA using HPLC-purified polypeptides was found to be more sensitive than immunoblotting for detecting antibody. 86% of sera with precipitating anti-nRNP antibodies were positive in the ELISA, as were all sera with precipitating anti-Sm antibodies. Patients with rheumatoid arthritis (RA), Sjögrens syndrome (SS) and undifferentiated connective tissue disease (UCTD) had low levels of anti-p67 with a prevalence 11.6% and 18%, respectively, whilst patients with systemic lupus erythematosus (SLE) and mixed connective tissue disease (MCTD) had high levels and prevalence rates of 55.2% and 80%, respectively. Anti-B or anti-D antibodies were detected at high levels in SLE (prevalence 30%) but were found rarely in UCTD and MCTD (prevalence 7% and 10%) and not at all in RA or SS sera.

Abstract
Autoimmunity can be accelerated in several genetically prone murine models and can even be induced in normal mice by treatment with interferon (IFN) or IFN-inducers. Several cases of IFN-induced autoimmune disease in humans also have been observed; however, more striking is the fact that some of the clinical manifestations in autoimmune diseases and many of the immunological aberrations can be mediated or enhanced by IFN. The finding of high levels of circulating IFN in many patients may be highly significant in that respect, and the characterization of the predominant type of IFN as an unusual acid-labile IFN-alpha may indicate an infectious etiologic agent in autoimmunity, since this peculiar IFN was mostly associated with viral infections in vivo or in vitro. The induction of MHC class II antigens on previously HLA-DR or Ia negative cells appears to be caused primarily by IFN-gamma and may have a central role in the pathogenesis of autoimmunity in susceptible individuals. Such aberrant HLA-DR expression on nonlymphoid cells can be detected early in the disease in the target organs of many varied autoimmune conditions and may trigger a cascade of self-directed, uncontrolled immune response in conjunction with other factors.

Abstract
We identified eight patients whose sera contained autoantibodies to the U2 small nuclear ribonucleoprotein (snRNP), an RNA protein particle involved in the splicing of newly transcribed messenger RNA. Each of these patients had an overlap syndrome that included features of either systemic lupus erythematosus (SLE), scleroderma, and/or polymyositis. We then used these sera to characterize the autoantigenic polypeptides of the U1 and U2 snRNP particles. In immunoblots, all sera contained antibodies to the B" polypeptide of the U2 snRNP. A subset of these sera that more effectively immunoprecipitated the native U2 particle contained an additional antibody system that recognized the A' polypeptide of this snRNP. Antibodies eluted from the B" protein bound the A polypeptide of the U1 snRNP and vice versa. Moreover, antibodies to the B" polypeptide were accompanied by antibodies to the 68K and C polypeptides of the U1 snRNP. Finally, the A' and B" polypeptides remained physically associated after the U2 particle was cleaved with RNase. Thus these sera contain multiple autoantibody systems that, at one level, target two physically associated antigenic polypeptides of the U2 particle and, at another, target two snRNP particles which are associated during the splicing of premessenger RNA. These linked autoantibody sets provide further evidence that intact macromolecular structures are targeted by the immune response in SLE and related diseases.

Abstract
This review presents evidence for the immunopathogenesis of psoriasis. T lymphocytes with human lymphocyte antigen (HLA)-DR molecules and receptors for interleukin 2 were found in the dermis of psoriatic plaques, suggesting the presence of activated T cells in these lesions. Keratinocytes in active plaques demonstrated HLA-DR molecules on their surfaces. These immunologic abnormalities were reversible with medical therapy. Keratinocyte HLA-DR expression was associated with an increased incidence of psoriatic arthritis. We propose that HLA-DR + keratinocytes and Langerhans cells in plaques could activate dermal T cells directly in an autologous mixed leucocyte/epithelial cell reaction. Alternatively, they could present an unknown autologous or exogenous antigen to T lymphocytes. T cell activation would then lead to the release of mediators of inflammation, and possibly of epidermal growth factors. This hypothesis also provides an explanation for the chronicity of psoriasis. Most of the therapies used to treat psoriasis suppress cellular immune function and inflammation. These include ultraviolet irradiation, cyclosporine, corticosteroids, methotrexate, anthralin, and retinoids.

Abstract
Polyadenylation of pre-mRNAs in the nucleus involves a specific endonucleolytic cleavage, followed by the addition of approximately 200 adenylic acid residues. We have assayed HeLa nuclear extracts for the activity that catalyzes the poly(A) addition reaction. The authenticity of the in vitro assay was indicated by the observation that the poly(A) tract added in vitro is approximately 200 nucleotides in length. We have fractionated nuclear extracts in order to define components involved in specific poly(A) addition. No single fraction from DEAE-Sephacel chromatography of a HeLa nuclear extract possessed the specific poly(A) addition activity. However, if the various fractions were recombined, activity was restored, indicating the presence of multiple components. Further fractionation revealed the presence of at least two factors necessary for the poly(A) addition reaction. The reconstituted system retains the characteristics and specificity seen in the crude extract. Additional purification of one of the factors strongly suggests it to be a previously characterized poly(A) polymerase which, when assayed in the absence of the other factor, can add AMP to an RNA terminus but without specificity. Thus, the other component of the reaction may provide specificity to the process. In contrast to the 3' cleavage reaction, the poly(A) addition machinery does not possess an essential RNA component, as assayed by micrococcal nuclease digestion, nor do anti-Sm sera inhibit the reaction. Thus, the total process of formation of a polyadenylated mRNA 3' end is complex and requires the concerted action of distinct nuclear components.

Abstract
Four patients with severe psoriasis have been treated with oral cyclosporine for 6 months. Two had generalized erythroderma and two had extensive plaque-type psoriasis; all had either become unresponsive to or were unable to use other accepted treatments. All four patients responded rapidly and were completely clear of psoriasis within 3 weeks of beginning therapy. Initial doses ranged from 7.5 to 8.5 mg/kg/day. Mild reversible nephrotoxicity occurred in the one patient whose cyclosporine trough level briefly exceeded 200 ng/ml. Cyclosporine may offer an alternative therapeutic modality in the management of erythrodermic or severe resistant plaque-type psoriasis. The effectiveness of cyclosporine in psoriasis underscores the putative role of cell-mediated immune factors in the pathogenesis of psoriasis.

Abstract
A U2 small nuclear RNA-associated protein, designated B'', was recently identified as the target antigen for autoimmune sera from certain patients with systemic lupus erythematosus and other rheumatic diseases. Such antibodies enabled us to isolate cDNA clone lambda HB''-1 from a phage lambda gt11 expression library. This clone appeared to code for the B'' protein as established by in vitro translation of hybrid-selected mRNA. The identity of clone lambda HB''-1 was further confirmed by partial peptide mapping and analysis of the reactivity of the recombinant antigen with monospecific and monoclonal antibodies. Analysis of the nucleotide sequence of the 1015-base-pair cDNA insert of clone lambda HB''-1 revealed a large open reading frame of 800 nucleotides containing the coding sequence for a polypeptide of 25,457 daltons. In vitro transcription of the lambda HB''-1 cDNA insert and subsequent translation resulted in a protein product with the molecular size of the B'' protein. These data demonstrate that clone lambda HB''-1 contains the complete coding sequence of this antigen. The deduced polypeptide sequence contains three very hydrophilic regions that might constitute RNA binding sites and/or antigenic determinants. These findings might have implications both for the understanding of the pathogenesis of rheumatic diseases as well as for the elucidation of the biological function of autoimmune antigens.

Abstract
We describe autoantibodies reactive with the signal-recognition particle (SRP) in serum of a patient with polymyositis. The serum specifically immunoprecipitated the SRP from human erythroleukemia (K562) cell extracts. Analysis of immunoblots revealed that the serum contained autoantibodies specific for the 54-kDa protein of the SRP but had little or no reactivity with its other five proteins. Indirect immunofluorescence of human laryngeal carcinoma (HEp-2) cells confirmed that the ribonucleoprotein immunoprecipitated by this serum is found mainly in the cytoplasm. This autoimmune serum may be useful for studying the function of the 54-kDa subunit of the SRP in binding to signal sequences or in interacting with other components of the translational machinery.

Abstract
We have previously shown that sera from some patients with SLE and related disorders contain autoantibodies to a DNA-binding protein complex designated p70/p80. The present study shows that anti-p70/p80 autoantibodies are frequently accompanied by anti-DNA antibodies and cryoglobulins. When the cryoglobulins were isolated, they were found to be specifically enriched in both anti-p70/p80 and anti-DNA activities. The anti-p70/p80 and anti-DNA antibodies were found to be distinct populations of autoantibodies rather than a single crossreactive species, since they could be separated from one another by chromatography on DNA-cellulose. Certain human anti-DNA mAbs could inhibit the binding of autoimmune polyclonal anti-p70/p80 antibodies to p70/p80, suggesting that anti-DNA antibodies might also associate with the variable regions of some anti-p70/p80 antibodies in the cryoglobulins. Binding of one murine anti-p70/p80 mAb (111-12) also was inhibited by certain human anti-DNA mAbs, but the binding of another murine mAb (162-11) to a different epitope of p70/p80 was not. These studies suggest that certain anti-DNA antibodies may interact with the variable regions of a population of anti-p70/p80 antibodies. The cryoglobulins found in the sera containing both anti-p70/p80 and anti-DNA antibodies may represent immune complexes consisting, in part, of idiotype and antiidiotype.
