Abstract
Hepatocellular carcinoma (HCC) is a molecularly heterogeneous solid malignancy, and its fitness may be shaped by how its tumor cells evolve. However, ability to monitor tumor cell evolution is hampered by the presence of numerous passenger mutations that do not provide any biological consequences. Here we develop a strategy to determine the tumor clonality of three independent HCC cohorts of 524 patients with diverse etiologies and race/ethnicity by utilizing somatic mutations in cancer driver genes. We identify two main types of tumor evolution, i.e., linear, and non-linear models where non-linear type could be further divided into classes, which we call shallow branching and deep branching. We find that linear evolving HCC is less aggressive than other types. GTF2IRD2B mutations are enriched in HCC with linear evolution, while TP53 mutations are the most frequent genetic alterations in HCC with non-linear models. Furthermore, we observe significant B cell enrichment in linear trees compared to non-linear trees suggesting the need for further research to uncover potential variations in immune cell types within genomically determined phylogeny types. These results hint at the possibility that tumor cells and their microenvironment may collectively influence the tumor evolution process.

Abstract
Clinical applications of precision oncology require accurate tests that can distinguish true cancer-specific mutations from errors introduced at each step of next-generation sequencing (NGS). To date, no bulk sequencing study has addressed the effects of cross-site reproducibility, nor the biological, technical and computational factors that influence variant identification. Here we report a systematic interrogation of somatic mutations in paired tumor-normal cell lines to identify factors affecting detection reproducibility and accuracy at six different centers. Using whole-genome sequencing (WGS) and whole-exome sequencing (WES), we evaluated the reproducibility of different sample types with varying input amount and tumor purity, and multiple library construction protocols, followed by processing with nine bioinformatics pipelines. We found that read coverage and callers affected both WGS and WES reproducibility, but WES performance was influenced by insert fragment size, genomic copy content and the global imbalance score (GIV; G > T/C > A). Finally, taking into account library preparation protocol, tumor content, read coverage and bioinformatics processes concomitantly, we recommend actionable practices to improve the reproducibility and accuracy of NGS experiments for cancer mutation detection.

Abstract
BACKGROUND The frequency of cancer, neurologic degeneration and mortality in xeroderma pigmentosum (XP) patients with defective DNA repair was determined in a four decade natural history study. METHODS All 106 XP patients admitted to the National Institutes of Health from 1971 to 2009 were evaluated from clinical records and follow-up. RESULTS In the 65 per cent (n=69) of patients with skin cancer, non-melanoma skin cancer (NMSC) was increased 10,000-fold and melanoma was increased 2000-fold in patients under age 20. The 9 year median age at diagnosis of first non-melanoma skin cancer (NMSC) (n=64) was significantly younger than the 22 year median age at diagnosis of first melanoma (n=38)-a relative age reversal from the general population suggesting different mechanisms of carcinogenesis between NMSC and melanoma. XP patients with pronounced burning on minimal sun exposure (n=65) were less likely to develop skin cancer than those who did not. This may be related to the extreme sun protection they receive from an earlier age, decreasing their total ultraviolet exposure. Progressive neurologic degeneration was present in 24% (n=25) with 16/25 in complementation group XP-D. The most common causes of death were skin cancer (34%, n=10), neurologic degeneration (31%, n=9), and internal cancer (17%, n=5). The median age at death (29 years) in XP patients with neurodegeneration was significantly younger than those XP patients without neurodegeneration (37 years) (p=0.02). CONCLUSION This 39 year follow-up study of XP patients indicates a major role of DNA repair genes in the aetiology of skin cancer and neurologic degeneration.

Abstract
One of the obstacles of BMT that limits its efficacy is failure to eradicate the original tumor. The incidence of tumor relapse is particularly high after autologous BMT. Natural killer (NK) cells comprise various subsets that can express inhibitory receptors for MHC class I determinants. We have recently demonstrated that blockade of NK-cell inhibitory receptors can augment antitumor effects in vitro and in vivo. However, breakdown of tolerance and autoreactivity may occur as a result of the inhibition of NK-cell inactivation to self MHC determinants. We have utilized F(ab')2 fragments of monoclonal antibody, 5E6, against Ly49C/I inhibitory receptors, which are expressed on 35% to 60% of NK cells in H2b strains of mice and are specific for H2Kb, to investigate the effect of inhibitory-receptor blockade on syngeneic bone marrow cell (BMC) and tumor cell growth. We show that treatment of interleukin 2-activated C57BL/6 (B6, H2b) SCID-mouse NK cells with 5E6 F(ab')2 fragments during 48-hour coculture resulted in autoreactivity against syngeneic BMCs as demonstrated by suppression of myeloid reconstitution on day 14 post-BMT. However, this suppressive effect was transient and normalized by day 21 post-BMT. In contrast, blockade of inhibitory receptors during 24-hour coculture had no adverse effects on myeloid reconstitution after BMT. Furthermore, under the same coculture conditions, NK cell-mediated purging of C1498 leukemia cells contaminating syngeneic BMCs was more effective with inhibitory-receptor blockade, leading to a significantly higher proportion of animals with long-term survival compared to the control recipients. These results demonstrate that short-term in vitro blockade of inhibitory receptors can augment antitumor activity without long-term inhibitory effects on BMCs and thus may be of potential use in the purging of contaminating tumor cells prior to autologous BMT.

Abstract
Because of the pivotal role the proteasome plays in apoptosis, inhibitors of this enzyme, such as PS-341, provide a great opportunity for exploring synergy between proteasome inhibition and other apoptosis-inducing agents. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) can selectively induce apoptosis in tumor cells. In overnight assays, combinations of PS-341 and TRAIL were much more effective than either agent alone in promoting apoptosis of a murine myeloid leukemia, C1498, and a murine renal cancer, Renca. For C1498 cells, apoptosis sensitization by PS-341 affected neither the activity of nuclear factor kappaB (NF-kappaB) nor the levels of most antiapoptotic proteins. However, reductions in the antiapoptotic protein c-FLIP in response to PS-341 were observed in both C1498 and Renca cells. Treatment of normal bone marrow mixed with C1498 tumor cells for 18 hours with a combination of PS-341 and TRAIL resulted in a specific depletion of the tumor cells. Upon transfer to irradiated syngeneic recipient mice, mixtures treated with the PS-341 plus TRAIL combination resulted in enhanced long-term tumor-free survival of mice. These data therefore support the targeting of apoptotic pathways in tumor cells, using combinations of agents such as PS-341 and TRAIL that interact synergistically to preferentially promote tumor cell apoptosis.

Abstract
Natural killer (NK) cells are the major effectors of acute rejection of incompatible bone marrow cell (BMC) grafts in lethally irradiated mice. The immunogenetics of BMC rejection are largely controlled by the coexpression (or not) of inhibitory and stimulatory Ly49 receptors whose ligands are class I major histocompatibility complex (MHC) molecules. The majority of the BMC rejection studies involved low numbers of BMCs that were resisted by host NK cells. In the present study, larger numbers of BMCs were given in which rejection was not detected and the role of different Ly49 NK subsets not presumably involved in the rejection of a particular BMC haplotype was examined. Surprisingly, the data show that the removal of NK cell subsets expressing Ly49 inhibitory receptors for donor class I antigens, which would be predicted to have no effect on the BMC rejection capability, resulted in the marked rejection of BMCs where no resistance was normally seen. These results extend the "missing self" hypothesis to suggest that NK Ly49 inhibitory receptors can both inhibit activation and killing by those cells, but also can in some way influence the function of NK cells that do not express that inhibitory receptor in a cell-cell interaction. This suggests that caution must be exercised before removal of host NK cell subset is applied clinically because enhanced BMC rejection may result. Altering the balance of Ly49 NK subsets may also affect other in vivo activities of these cells.

Abstract
Natural killer (NK) cells mediate acute rejection of bone marrow, but not solid tissue, allografts in lethally irradiated mice. Precisely how and why this rejection occurs is still unclear. In allogeneic bone marrow transplantation (BMT), a spectrum of results is possible; one result can be marrow graft failure due to host rejection of the graft by NK and T cells and, at the opposite spectrum, the occurrence of graft-versus-host disease (GVHD). Donor NK cells, however, appear capable of improving donor engraftment without giving rise to GVHD and thus may be of use as an immunotherapy following BMT. As NK-cell inhibitory receptors play a role in bone marrow cell rejection, these same inhibitory receptors may also affect NK responses towards tumor cells. It has been demonstrated that blocking the interaction of inhibitory receptors with MHC determinants on tumor cells can result in greater antitumor effects. Thus, NK cells are capable of mediating both positive and negative effects during BMT depending on whether they are of host versus donor origin and their state of activation. Understanding their role in BMT provides insights as to their physiological roles and points the way to potential clinical uses.

Abstract
Subsets of natural killer (NK) cells are characterized by the expression of inhibitory and/or stimulatory receptors specific for major histocompatibility complex (MHC) class I determinants. In mice, these include the Ly49 family of molecules. One mechanism by which tumor cells may evade NK cell killing is by expressing the appropriate MHC class I and binding inhibitory Ly49 receptors. Therefore, the question of whether blocking the interaction between the Ly49 inhibitory receptors on NK and MHC class I cells on tumor cells augments antitumor activity was investigated. Blockade of Ly49C and I inhibitory receptors using F(ab')(2) fragments of the 5E6 monoclonal antibody (mAb) resulted in increased cytotoxicity against syngeneic tumors and decreased tumor cell growth in vitro. The effect of 5E6 F(ab')(2) was specific for the MHC of the tumor, as the use of F(ab')(2) of the mAb against Ly49G2 failed to increase NK activity. Treatment of leukemia-bearing mice with 5E6 F(ab')(2) fragments or adoptive transfer of NK cells treated ex vivo with the F(ab')(2) resulted in significant increases in survival. These results demonstrate that blockade of NK inhibitory receptors enhances antitumor activity both in vitro and in vivo, suggesting that NK inhibitory receptors can be responsible for diminishing antitumor responses. Therefore, strategies to block inhibitory receptors may be of potential use in increasing the efficacy of immunotherapy. (Blood. 2001;97:3132-3137)

Abstract
Subsets of murine natural killer (NK) cells exist that express the Ly-49 family of molecules that recognize different major histocompatibility complex (MHC) determinants. Bone marrow transplantation studies were performed to examine the in vivo functions of 2 of these subsets. Subsets of Ly-49A and Ly-49G2 NK share specificity for the same MHC class 1 ligand, D(d), binding of which results in an inhibitory signal to the NK cell but allows them to lyse H2(b) targets in vitro. We therefore examined the ability of these subsets to reject H2(b) bone marrow cell allografts in lethally irradiated mice. Surprisingly, depletion of Ly-49A(+) NK cells in BALB/c or B10.D2 mice (both H2(d)) had no effect on the rejection of H2(b) BMC. However, Ly-49A depletion did partially abrogate the ability of B10.BR (H2(k)) mice to reject H2(b) allografts. Although depletion of either Ly-49A(+) or Ly-49G2(+) NK cells alone had no effect on the ability of B10.D2 mice to reject H2(b) BMC, depletion of both subsets dramatically and synergistically abrogated rejection. Studies with various B10 congenic mice and their F(1) hybrids indicate that this synergy between Ly49A and Ly4G2 depletion occurs in every instance. Thus, Ly-49A(+) NK cells appear to play a role in the rejection H2(b) bone marrow allografts, but, in most strains of mice studied, Ly-49G2(+) NK cells must also be eliminated. The putative roles of these NK cell subsets in clinical transplantation remains to be elucidated. (Blood. 2000;95:3840-3844)

Abstract
We present data on the strain distribution and functional characteristics of the Ly-49 receptors A, C/I, D, and G2 on DX5+ natural killer (NK) cells. We have examined tyrosine phosphorylation of the Ly-49 molecules, regulation of NK cytotoxic functions, and in vivo marrow rejection capability. The flow cytometry results demonstrate a diverse and complex pattern of expression of the Ly-49 receptors in the 11 strains examined. The vast majority of NK cells express Ly-49s, although some NK1.1+ CD3+ cells also express these receptors. The results of our functional analysis indicate that H-2Dd was able to inhibit the function of Ly-49G2+ NK cells, not only in B6 mice, but also by NK cells derived from several haplotypes. The examination of Ly-49 receptor tyrosine phosphorylation, which is a biochemical measure of inhibitory function, was consistently observed in the 11 mouse strains examined. In contrast, analysis of Ly-49D function suggests its expression appears to be more restricted and that H-2Dd is an activating ligand for this receptor. In addition, the in vivo examination of both inhibitory (Ly-49G2) and activating (Ly-49D) receptors demonstrated regulatory roles of these class I binding receptors in marrow transplantation.

Abstract
Prolactin (PRL) is a neuroendocrine hormone that influences immune and hematopoietic development. The mechanism of action of this hormone in vivo remains unclear; therefore, we assessed the effects of PRL on hematopoiesis in vivo and in vitro. Normal resting mice were treated with 0, 1, 10, or 100 microg of recombinant human prolactin (rhPRL) for 4 consecutive days and euthanized on the fifth day for analysis of myeloid and erythroid progenitors in the bone marrow and spleen. Both frequencies and absolute numbers of splenic colony-forming unit granulocyte-macrophage (CFU-GM) and burst-forming unit-erythroid (BFU-e) were significantly increased in mice receiving rhPRL compared to the controls that had received saline only. Bone marrow cellularities were not significantly affected by any dose of rhPRL, but the absolute numbers and frequencies of bone marrow CFU-GM and BFU-e were augmented by rhPRL. These results suggest that rhPRL can promote hematopoiesis in vivo. Because rhPRL augments myeloid development in vivo, we examined the potential of the hormone to reverse the anemia and myelosuppression induced by azidothymidine (AZT). Mice were given rhPRL injections concurrent with 2.5 mg/mL AZT in drinking water. rhPRL partially restored hematocrits in the animals after 2 weeks of treatment and increased CFU-GM and BFU-e in both spleens and bone marrow. The experiments with AZT and rhPRL support the conclusion that the hormone increases myeloid and erythroid progenitor numbers in vivo, and they suggest that the hormone is clinically useful in reversing myelosuppression induced by AZT or other myeloablative therapies.

Abstract
Recombinant human growth hormone (rhGH) was administered to mice after syngeneic bone marrow transplantation (BMT) to determine its effect on hematopoietic reconstitution. BALB/c mice were given 10 microg intraperitoneal injections of rhGH every other day for a total of 10 injections following syngeneic BMT. Mice that received rhGH exhibited significant increases in total hematopoietic progenitor cell content (colony-forming unit-culture) in both bone marrow and spleen. Erythroid cell progenitor content (burst-forming unit-erythroid) was also significantly increased after rhGH treatment. Analysis of peripheral blood indicated that administration of rhGH resulted in significant increases in the rate of white blood cell and platelet recovery. Granulocyte marker 8C5+ cells were also increased in the bone marrow and spleens of treated mice. Red blood cell, hematocrit, and hemoglobin levels were increased at all time points after rhGH treatment. No significant pathologic effects or weight gain were observed in mice receiving repeated injections of 10 microg rhGH. Thus, rhGH administration after syngeneic BMT promoted multilineage hematopoietic reconstitution and may be of clinical use for accelerating hematopoiesis after autologous BMT.

Abstract
Natural killer cells mediate the specific rejection of bone marrow cell (BMC) allografts in lethally irradiated mice. The Ly-49 family of molecules present on subsets of murine NK cells appears capable of binding class I MHC molecules, resulting in transmission of an inhibitory signal to the NK cell. These Ly-49 family members have been shown to have an immunoreceptor tyrosine-based inhibitory motif that is responsible for the inhibitory signal. However, a new Ly-49 family member was found that lacks this motif, Ly-49D, and evidence suggests that this may be an activating receptor. We therefore compared the role of the activating Ly-49 member with NK cells bearing inhibitory Ly-49 receptors in BMC rejection. Depletion of Ly-49D+ NK cells in H-2b mice abrogated their ability to reject H-2d BMC allografts. Similarly, Ly-49C+ NK cells also were shown to mediate the specific rejection of H-2d BMC. When both subsets were depleted, an additive enhancement of BMC engraftment was observed, indicating that both subsets play a role in the rejection of allogeneic H-2-homozygous H-2d BMC. However, rejection of H-2b × d or D8 (H-2b, Dd transgene) BMC allografts was unaffected by Ly-49C+ NK cell depletion in H-2b mice. In marked contrast, depletion of Ly-49D+ NK cells in H-2b mice totally abrogated the rejection of H-2b × d heterozygous BMC in support of in vitro data suggesting that Ly-49D+ NK cells receive activating signals. Therefore, NK subsets demonstrate a differential ability to reject H-2 homozygous and heterozygous BMC.

Abstract
The c-erbB-2 gene overexpression plays a major role in the pathogenesis of breast cancer. Binding studies detected a nuclear matrix protein (NMP) in human breast tumor tissues that recognizes a matrix attachment region (MAR) in the immediate vicinity of the c-erbB-2 gene promoter. This NMP is expressed in breast tumor tissues and cell lines along with c-erbB-2, but is not found in corresponding normal tissues. Furthermore, when NMP purified from the breast tumors by its affinity to the MAR sequence is added to nuclear extracts of breast cancer cells, it selectively stimulates the binding of the NF-kappaB transcription factor to DNA. A model is suggested in which the association of the MAR-like sequence with the nuclear matrix raises the local concentration of the specific NMP, which in turn interacts with the nuclear factor NF-kappaB to increase its local level. Such a complex could explain at a molecular level the "increase in NF-kappaB DNA binding activity" often observed in c-erbB-2- and BRCA1-positive human breast tumors. The increased NF-kappaB activity could thereby contribute to breast cancer progression.

Abstract
CD40 is a molecule present on multiple cell types including B lymphocyte lineage cells. CD40 has been shown to play an important role in B cell differentiation and activation in vitro, although little is known concerning the effects of CD40 stimulation in vivo. We therefore examined the effects of CD40 stimulation in mice using a syngeneic bone marrow transplantation (BMT) model in an effort to augment B cell recovery after high dose therapy with hematopoietic reconstitution. After the BMT, mice were treated with or without 2-6 microg of a soluble recombinant murine CD40 ligand (srmCD40L) given intraperitoneally twice a week. A significant increase in B cell progenitors (B220+/ surface IgM-) was observed in the bone marrow of mice receiving the srmCD40L. The treated recipients also demonstrated improved B-cell function with increases in total serum immunoglobulin and increased splenic mitogen responsiveness to LPS being noted. Additionally, srmCD40L treatment promoted secondary lymphoid organ repopulation, accelerating germinal center formation in the lymph nodes. Total B cell numbers in the periphery were not significantly affected even with continuous srmCD40L administration. Lymphocytes obtained from mice treated with the ligand also had increases in T cell mitogen and anti-CD3 mAb responsiveness and acquired the capability to produce IL-4. Surprisingly, treatment with srmCD40L also produced hematopoietic effects in mice, resulting in an increase of BM and splenic hematopoietic progenitor cells in the mice after BMT. Treatment with srmCD40L significantly increased granulocyte and platelet recovery in the peripheral blood. Incubation of BMC with srmCD40L in vitro also resulted in increased progenitor proliferation, demonstrating that the hematopoietic effects of the ligand may be direct. Thus, stimulation of CD40 by its ligand may be beneficial in accelerating both immune and hematopoietic recovery in the setting of bone marrow transplantation.

Abstract
NK cells can mediate the specific rejection of bone marrow but not solid tissue allografts in lethally irradiated mice. NK cells are also responsible for the phenomenon of "hybrid resistance' in which F1 hybrid H-2 heterozygous mice can reject parental H-2 homozygous bone marrow grafts. Ly-49C and Ly-49 G2 are markers identified on subsets of NK cells. While Ly-49C+ NK cells have been demonstrated to mediate the specific rejection of H-2d bone marrow allografts, the role of the Ly-49 G2+ NK subset is unclear because depletion of this subset in vivo did not affect splenic NK activity against tumor targets. Through bone marrow transplantation typing studies, we demonstrate that Ly-49 G2+ NK cells complement Ly-49C+ NK cells in that they specifically mediate the rejection of H-2b bone marrow allografts in lethally irradiated mice. In support of this, depletion of the Ly-49C+ NK subset in vivo also enhanced the ability of the mice to reject H-2b bone marrow cells suggesting that the depletion was augmenting the ability of the Ly-49 G2+ NK cells to reject the marrow allografts. Depletion of Ly-49 G2+ NK cells in F1 hybrid mice abrogated their ability to reject parental H-2b but not H-2d bone marrow grafts. Therefore, Ly-49 G2 denotes a subset of NK cells that appears to play a critical role in the recognition of H-2b bone marrow cells in allogeneic and F1 hybrid mice.

Abstract
NK cells are able to reject bone marrow allografts in lethally irradiated mice. 5E6 is a marker expressed on a subset of NK cells that is responsible for the rejection of H-2d homozygous bone marrow cell (BMC) allografts. This suggests that the 5E6+ NK cell subset somehow recognizes and is deleterious for H-2d BMC. However, unlike Ly-49+ NK cells, 5E6+ cells are not deleted or even down-regulated in H-2d-homozygous mice. We wanted to determine, therefore, the role of the 5E6+ and 5E6- NK cell subsets in the normal physiologic regulation of hematopoiesis in H-2d strains of mice. Surprisingly, both in vivo depletion studies of normal mice and studies in which the subsets were purified and cultured with syngeneic BMC in vitro demonstrated that in H-2d mice, the 5E6+ subset of NK cells did not inhibit, but instead promoted, growth of H-2d BMC. Depletion of the 5E6+ subset also resulted in decreased marrow engraftment after syngeneic bone marrow transplantation in H-2d mice. Analysis of the cell culture supernatants of the purified subsets indicated that the functional effects of the subsets on hematopoiesis correlated with the relative amounts of hematopoietic growth-promoting cytokines produced by the NK cells. These results demonstrate that physiologically relevant subsets of NK cells exist that are involved in the homeostatic regulation of hematopoiesis and that they can be distinguished on the basis of 5E6 expression.

Surprisingly, both in vivo depletion studies of normal mice and studies in which the subsets were purified and cultured with syngeneic BMC in vitro demonstrated that in H-2d mice, the 5E6+ subset of NK cells did not inhibit, but instead promoted, growth of H-2d BMC. Depletion of the 5E6+ subset also resulted in decreased marrow engraftment after syngeneic bone marrow transplantation in H-2d mice. Analysis of the cell culture supernatants of the purified subsets indicated that the functional effects of the subsets on hematopoiesis correlated with the relative amounts of hematopoietic growth-promoting cytokines produced by the NK cells. These results demonstrate that physiologically relevant subsets of NK cells exist that are involved in the homeostatic regulation of hematopoiesis and that they can be distinguished on the basis of 5E6 expression.

Abstract
We examined the proposed role of human chromosome 21 in determining the cellular sensitivity to human alpha, beta, and gamma interferons (HuIFN-alpha, -beta, and -gamma) and the expression of the receptors for the HuIFNs with the use of mouse-human hybrid cells containing human chromosome 21. Hybrid cells (WA17) containing three copies of human chromosome 21 showed specific displaceable binding of 125I-labeled HuIFN-alpha 2 (125I-HuIFN-alpha 2), which was not observed with mouse parent (A9) cells. Crosslinking of 125I-HuIFN-alpha 2 bound to WA17 cells with disuccinimidyl suberate yielded a complex of Mr approximately equal to 150,000 similar to the 125I-HuIFN-alpha 2-receptor complex obtained with human cells as described earlier. Such a complex was not obtained with mouse parent (A9) cells or with hybrid cells containing certain other human chromosomes but not chromosome 21. Mice inoculated with mouse-human hybrid cells containing human chromosome 21 produce antibodies that block the antiviral action of HuIFN-alpha and -beta on human cells. Such antibodies could immunoprecipitate the 125I-HuIFN-alpha 2-receptor complex obtained from human cells but not free 125I-HuIFN-alpha 2, indicating that these antibodies were directed against the receptor. WA17 hybrid cells were highly sensitive to the antiviral action of HuIFN-alpha 2, -alpha (Le) and -beta but were completely insensitive to HuIFN-gamma. Furthermore, 125I-HuIFN-gamma showed specific binding to human WISH cells but not to WA17 hybrid cells or A9 mouse cells. The results indicate that the receptors for HuIFN-alpha and -beta but not for HuIFN-gamma are specified by human chromosome 21. Hybrid cells containing one, two, or three copies of human chromosome 21 were found to be increasingly sensitive to HuIFN-alpha 2, indicating that a chromosome 21-specified component (possibly the HuIFN-alpha receptor) may be a limiting factor in the cellular sensitivity to HuIFN-alpha.

Abstract
Interferon (IFN) action on cells must begin with an interaction with cellular receptors. Binding and cross-linking experiments reported earlier with purified 125I-labeled recombinant human (Hu) IFN-alpha 2 have revealed that IFN-alpha 2 binds to a specific macromolecular receptor on human cells (Joshi et al., J. Biol. Chem. 257, 13884-13887, 1982). Based on indirect evidence such as neutralization of the antiviral action of IFN preparations by gangliosides and binding of IFNs to gangliosides coupled to solid supports, it has been suggested by various investigators that gangliosides may be a part of the IFN-alpha/beta receptors. Experiments presented here indicate that gangliosides could block the antiviral activity of HuIFN-beta, but not of HuIFN-alpha, although both species of IFN bound strongly to gangliosides coupled to poly-L-lysine-agarose. Furthermore, gangliosides did not inhibit the binding of 125I-labeled HuIFN-alpha 2 to specific receptors on human cells, and this binding was competed out by unlabeled HuIFN-alpha 2 and HuIFN-alpha(LE) which were preincubated with gangliosides. However, the capacity of HuIFN-beta to compete for the receptors was abolished by preincubation with gangliosides. These results were confirmed by cross-linking experiments to identify the IFN-receptor complex by gel electrophoresis. The results indicate that at least in the case of HuIFN-alpha species, the ganglioside binding is apparently not at the active site of the IFN molecules required for interaction with the receptors on the cell surface.
