Abstract
Data are scarce regarding both the safety and immunogenicity of the BNT162b2 mRNA COVID-19 vaccine in patients undergoing immune cell therapy; thus, we prospectively evaluated these two domains in patients receiving this vaccine after allogeneic hematopoietic cell transplantation (HCT; n = 66) or after CD19-based chimeric antigen receptor T cell (CART) therapy (n = 14). Overall, the vaccine was well tolerated, with mild non-hematologic vaccine-reported adverse events in a minority of the patients. Twelve percent of the patients after the first dose and 10% of the patients after the second dose developed cytopenia, and there were three cases of graft-versus-host disease exacerbation after each dose. A single case of impending graft rejection was summarized as possibly related. Evaluation of immunogenicity showed that 57% of patients after CART infusion and 75% patients after allogeneic HCT had evidence of humoral and/or cellular response to the vaccine. The Cox regression model indicated that longer time from infusion of cells, female sex, and higher CD19+ cells were associated with a positive humoral response, whereas a higher CD4+/CD8+ ratio was correlated with a positive cellular response, as confirmed by the ELISpot test. We conclude that the BNT162b2 mRNA COVID-19 vaccine has impressive immunogenicity in patients after allogeneic HCT or CART. Adverse events were mostly mild and transient, but some significant hematologic events were observed; hence, patients should be closely monitored.

Abstract
Posttransplantation lymphoproliferative disease (PTLD) is a potentially fatal disorder arising after solid organ or hematopoietic cell transplantation. Survival rates of PTLD with diffuse large B-cell lymphoma (DLBCL) phenotype have improved due to the introduction of rituximab, however, reports on curative management of refractory PTLD are scarce. Here, we describe successful management of three patients with refractory EBV-negative PTLD with chimeric antigen receptor T-cell (CAR-T) therapy. All patients continued calcineurin inhibitors throughout the whole course of treatment. T-cell immunophenotyping was performed on both the apheresed cells and CAR-T product to investigate the T-cell compartment subpopulations. All three patients responded to a single infusion of tisagenlecleucel and two of them achieved CR. Toxicity profile was similar to other patients with non-PTLD DLBCL treated with CAR-T. No transplanted graft dysfunction was observed during the course of therapy. To our knowledge, this is the first report demonstrating that patients with EBV-negative refractory PTLD may benefit from CAR-T therapy, similarly to other patients with relapse/refractory DLBCL. A larger cohort of patients is needed to further establish proof-of-concept.

Abstract
OBJECTIVES We aimed to determine the impact of washout period in patients with multiple myeloma between bortezomib-based induction regimens and the collection of stem cells. METHODS This was a single-center historical prospective study, including all sequential newly diagnosed patients with myeloma between 2012 and 2017 that were given a first-line bortezomib-based induction therapy (≤6 cycles) followed by stem cell collection (n = 75). RESULTS We found a statistically significant correlation between the days from last dose of bortezomib and both CD34+ cells/kg yield on the first collection day and the overall collected CD34+ cells/kg (r = .466, P < .001, and r = .341, P = .03, respectively). The optimal receiver operating curve's cutoff point was 8.5 days (79% sensitivity and 71% specificity, P = .001). On multivariate analysis, timing of last dose of bortezomib remained statistically significant (P = .01). Based on this, we developed a model to predict the total collected CD34+ cells/kg = 11.76 + 0.13 (timing in days of last dose of bortezomib) -0.1 (age) -1.39 (if female) -0.01 (≥PR) -1.35 (if prior radiation). CONCLUSIONS Timing of last dose of bortezomib may predict a successful collection. A washout period of 9 days is associated with a better collection yield. A prospective validation of this novel finding is required.

Abstract
Numerous adults' studies demonstrated that preaphaeresis CD34+ cells significantly correlate with the number of CD34+ cells collected by the aphaeresis procedure. Equivalent studies in children are scarce. We studied retrospectively 92 aphaeresis procedures performed following chemotherapy (44) or in steady state (48) in 60 pediatric patients (40 males, 20 females), median age of 7.5 years. Aphaeresis procedures were performed using a SPECTRA Optica (TERUMOBCT) continuous flow cell separator. CD34+ cell concentrations were assessed using flow cytometry. A highly significant correlation between peripheral CD34 cell count on the day of aphaeresis and CD34 cell yield per kg (R2 = .824, P < .0001) was demonstrated. A higher preaphaeresis CD34 cell count was demonstrated in patients with higher preaphaeresis white blood cell count, in patients with brain tumors, and in patients who received chemotherapy as part of their mobilization protocol. A threshold number of 20 peripheral CD34+ cell/μL was found to predict harvesting of 3 × 106 stem cells/kg, and 30 peripheral CD34+ cell/μL for harvesting of 5 × 106 stem cells/kg. This significant correlation between peripheral CD34 cell count and CD34 cell yield, and the threshold number of peripheral CD34 found to predict adequate harvesting can be useful in planning the optimal time for aphaeresis in children.

Abstract
High-dose therapy followed by autologous hematopoietic cell transplantation (HCT) prolongs overall survival in patients under 65 years old with relapsed aggressive lymphoma. We aimed to explore the toxicity and efficacy of HCT in patients over 65 years with aggressive lymphoma compared with younger patients. We compared the transplantation outcomes between patients ≥ 65 years (n = 58) and 55-64 years (n = 44) with chemosensitive aggressive lymphoma (DLBCL, MCL and TCL) that underwent HCT between 1999 and 2016 in the Tel-Aviv Medical Center. The median age was 68 (range, 65-74) and 61 (range, 55-64) years, respectively. There were no differences in the incidences of grade 3-4 mucositis, documented infections and pulmonary complications between the two groups. There was no difference in the incidences of secondary malignancies, relapse (p = .26), non-relapse mortality, (p = .77) and overall survival (p = .53). Multivariate analysis revealed that smoking was a risk factor for non-relapse mortality, while partial remission and > 2 lines of treatment prior HCT were associated with higher risk for relapse. Psycho-socioeconomic score was associated with prolonged hospitalization after HCT and recurrent hospitalizations. We conclude that patients ≥ 65 years old with aggressive lymphoma, compared to younger counterparts, have similar transplantation outcome. Improving habits and psychosocial factors may further improve outcomes in these patients.

Abstract
PB is a source of HSC, especially for autologous HCT in solid tumors. However, there is a risk of failing to achieve the target number of SC after mobilization with growth factors alone in patients who were heavily pretreated with chemotherapy or those in need for tandem transplants. SC were harvested from seven pediatric patients with solid tumors who were in need of autologous HCT following combination GCSF and plerixafor. Six of them received plerixafor after failing to achieve enough SC with GCSF only, while the seventh patient received the combined protocol upfront. All seven patients achieved the target number of SC according to their treatment protocol. There were no adverse events. All patients underwent autologous HCT using the harvested HSC and achieved full engraftment. A protocol for harvesting autologous HCT using GCSF and plerixafor is feasible and safe in children with solid tumors who had been heavily pretreated with chemotherapy or needed tandem transplants.

Abstract
BACKGROUND Janus kinase-2 (JAK2) is mutated in a high proportion of patients with polycythemia vera and in a smaller number with essential thrombocythemia and primary myelofibrosis. Mutated JAK2 is an important diagnostic marker for myeloproliferative neoplasm (MPN) and may also play a major role in the pathogenesis of MPN. OBJECTIVES To evaluate the prevalence of mutated JAK2 (JAK2-V617F) among patients with major intraabdominal vein thrombosis who had normal blood counts at diagnosis of the initial event. METHODS The medical records of patients who presented with a major intraabdominal venous thrombosis and normal peripheral blood counts were obtained. JAK2-V617F mutation status was determined by real-time polymerase chain reaction. RESULTS Twenty-two patients were available for this analysis and 9 (41%) were found to have JAK2-V617F. Patients with positive JAK2-V617F were younger and had more frequent clinical splenomegaly than those with wild-type JAK2. CONCLUSIONS A high proportion of patients presenting with "idiopathic" major intraabdominal vein thrombosis and normal blood counts carry JAK2-V617F. We recommend searching for the mutation in this clinical setting to detect patients with occult MPN.

Abstract
BACKGROUND Recent reports showed that children born with intrauterine growth restriction (IUGR) are at greater risk of experiencing verbal short-term memory span (STM) deficits that may impede their learning capacities at school. It is still unknown whether these deficits are modality dependent. METHODS This long-term, prospective design study examined modality-dependent verbal STM functions in children who were diagnosed at birth with IUGR (n = 138) and a control group (n = 64). Their STM skills were evaluated individually at 9 years of age with four conditions of the Visual-Aural Digit Span Test (VADS; Koppitz, 1981): auditory-oral, auditory-written, visuospatial-oral and visuospatial-written. Cognitive competence was evaluated with the short form of the Wechsler Intelligence Scales for Children--revised (WISC-R95; Wechsler, 1998). RESULTS We found IUGR-related specific auditory-oral STM deficits (p < .036) in conjunction with two double dissociations: an auditory-visuospatial (p < .014) and an input-output processing distinction (p < .014). Cognitive competence had a significant effect on all four conditions; however, the effect of IUGR on the auditory-oral condition was not overridden by the effect of intelligence quotient (IQ). CONCLUSIONS Intrauterine growth restriction affects global competence and inter-modality processing, as well as distinct auditory input processing related to verbal STM functions. The findings support a long-term relationship between prenatal aberrant head growth and auditory verbal STM deficits by the end of the first decade of life. Empirical, clinical and educational implications are presented.

Abstract
Chimerism analysis after allogeneic stem cell transplantation (allo-SCT) is an important diagnostic tool for the documentation of engraftment, early detection of graft failure, and recurrence of the disease. Current assays rely on the genetic polymorphism between the donor and the recipient, and allow semiquantitative or quantitative analysis of chimerism. The most common method in use is based on the amplification of the short tandem repeats (STR). This method, with 1% to 5 sensitivity, is useful for the documentation of engraftment, but is insufficient for the detection of minimal residual disease or early relapse, when medical intervention is urgently needed. Recently, single-nucleotide polymorphism (SNP) has been suggested as an alternative, more accurate system to monitor chimerism. The purpose of our study was to develop an easy, economical, and sensitive method for the detection of chimerism following allo-SCT using the SNP technology. Our approach is based on SNP patient-specific quantitative real-time polymerase chain reaction (PCR) using nonlabeled primers. Our results show that this allele-specific SNP real-time PCR approach is sensitive, relatively cheap, and offers a fast and reliable assay for the monitoring of hematopoietic engraftment and for the detection of minimal residual disease in patients after allo-SCT.

Abstract
Heparanase is a heparan sulfate-degrading endoglycosidase expressed by mature monocytes and myeloid cells, but not by immature hematopoietic progenitors. Heparanase gene expression is upregulated during differentiation of immature myeloid cells. PML-RARalpha and PLZF-RARalpha fusion gene products associated with acute promyelocytic leukemia abrogate myeloid differentiation and heparanase expression. AML-Eto, a translocation product associated with AML FAB M2, also downregulates heparanase gene expression. The common mechanism that underlines the activity of these three fusion gene products involves the recruitment of histone deacetylase complexes to specific locations within the DNA. We found that retinoic acid that dissociates PML-RARalpha from the DNA, and which is used to treat acute promyelocytic leukemia patients, restores heparanase expression to normal levels in an acute promyelocytic leukemia cell line. The retinoic acid effects were also observed in primary acute promyelocytic leukemia cells and in a retinoic acid-treated acute promyelocytic leukemia patient. Histone deacetylase inhibitor reverses the downregulation of heparanase expression induced by the AML-Eto fusion gene product in M2 type AML. In summary, we have characterized a link between leukomogenic factors and the downregulation of heparanase in myeloid leukemic cells.

Abstract
Selectin ligands are crucial components in the interaction between endothelial cells and extravasating cancer cells and, thus, play an important role in metastasis formation. Head-and-neck squamous cell carcinoma (HNSCC) variants expressing high levels of E48, a human Ly-6 protein (E48(hi)), expressed higher levels of the fucose-generating FX enzyme and of the fucosylated E-selectin ligand sLe(a) than cells expressing low levels of E48 (E48(lo)). Signaling through E48 upregulated expression levels of these molecules in HNSCC. In this work, we provide further evidence supporting the E48-FX-sLe(a) link by showing that FX antisense oligonucleotides reduced sLe(a) expression levels in HNSCC. We also show that E48 may be causally involved in regulating expression levels in HNSCC of 2 additional enzymes involved in the biosynthesis of sLe(a), namely, ST-30 and FucTIII. Also, selectin-mediated adhesion of E48(hi) variants to activated HUVECs was significantly higher than that of E48(lo) variants. Transfection experiments utilizing sense or antisense E48 cDNA indicated that E48 may be causally involved in this adhesion. Chemokines are involved in the extravasation process of tumor cells. The release of chemoattractants from HNSCC variants differing in E48 expression was therefore analyzed. HNSCC did not release any chemoattractants but induced the release of such factors from HUVECs. Supernatants from E48(hi) variants were significantly more efficient than E48(lo) cells at inducing the release of chemoattractants from HUVECs. Transfection experiments indicated that E48 may be causally involved in the induction of chemoattractant release from HUVECs. Angiogenesis is an important manifestation of cancer-endothelium interactions. We therefore assayed for the presence of angiogenic factors in culture supernatants of HNSCC. Supernatants from E48(lo) variants contained significantly higher amounts of PDGF than E48(hi) cells. Transfection experiments indicated that E48 may be causally involved. Taken together, our results suggest that E48 controls important interaction parameters between HNSCC and endothelial cells.

Abstract
Cells, including cancer cells, communicate with their microenvironment via various types of membrane receptors. An important down-stream effect of such interactions is a change in the molecular phenotype of the cells. The microenvironment-driven molecular evolution of cancer cells may induce either growth arrest or death of the cells or alternatively, boost their malignancy phenotype. In this paper we summarize studies from our own laboratory on interactions of cancer cells with microenvironmental ligands via two types of receptors that are not commonly associated with tumour progression i.e. the receptor for the Fc portion of IgG, and Ly-6 proteins of mouse and human origin. We also review information on interactions of tumour-associated chemokines and chemokine receptors with the corresponding microenvironmental factors. We demonstrate how these interactions may drive the molecular evolution of tumour cells and discuss the possible impact of this evolution on tumour progression.

Abstract
Fucose is an essential constituent of selectin ligands. These molecules mediate the initial contact between extravasating leukocytes and endothelial cells. The generation of GDP-L-fucose by the FX enzyme is the final step of fucose biosynthesis. Recently, we demonstrated that outside-in signaling regulates the expression of the FX enzyme in certain cancer cells. The present study demonstrates that the polyclonal activation of T and B cells significantly up-regulated the expression of the FX enzyme and of the fucosylated selectin ligands sLe-x and CLA. Treatment of T cells with FX antisense oligonucleotides significantly decreased selectin ligand expression upon activation. We conclude that FX is regulated by outside-in signals also in lymphocytes and that this enzyme is involved in the biosynthesis of selectin ligands in such cells. We propose that FX takes part in the cascade of events leading to the extravasation of activated lymphocytes.

Abstract
By differential display we demonstrated that antibody-mediated ligation of the GPI-linked protein product of E48, a newly discovered human Ly-6 gene, up-regulates the expression of the FX enzyme in 3 lines of head and neck squamous carcinoma cells. FX is responsible for the last step in the synthesis of GDP-L-fucose. The up-regulation of FX was E48 ligand-specific. 22AWT head and neck squamous carcinoma cells expressing high levels of E48 expressed significantly higher levels of FX than the E48 antisense transfected 22AWT cells (8-3 cells). The former cells also expressed higher levels of two major fucosylated glycans (the selectin ligand, Sialyl Lewis a, and VIM-2) than the E48 antisense transfectants. Conversely, transfection of cells from the 14CWT line expressing very low levels of E48 with E48 cDNA caused an up-regulated expression of FX and of the two fucosylated glycans in the 14C-CMV16 transfectants. Moreover, the expression levels of Sialyl Lewis a was significantly up-regulated on HNSCC upon ligation of E48 by anti-E48 antibodies. The functional significance of the E48-mediated up-regulation of Sialyl Lewis a was demonstrated in rolling experiments on E-selectin bearing surfaces under physiological conditions of shear flow and on tumor necrosis factor alpha-activated human umbilical venous endothelial cells. Only high E48/FX/Sialyl Lewis a expressing 14C-CMV16 cells could roll on purified E-selectin or establish E-selectin dependent rolling on the activated human umbilical venous endothelial cells. Low E48/FX/Sialyl Lewis a expressing 14CWT cells did not roll. These results show that E48 controls the expression of the FX enzyme and of certain fucosylated E-selectin ligands by HNSCC. E48 may thus function as a key regulator of the adhesiveness of these tumor cells to inflamed vessel walls expressing E-selectin.

Abstract
Ly-6E.1 is highly expressed in murine tumor cells with a high malignancy phenotype and may serve as a marker for such a phenotype. In this study, we examined the effects of various growth conditions and stress on the expression levels of Ly-6E.1 by tumor cells. Previous preliminary results have shown that murine DA3 mammary tumor cells expressing high levels of Ly-6E.1 (Ly-6(hi)) are more highly tumorigenic than the same tumor cells expressing low levels of this membrane protein (Ly-6(lo)). In this study, we demonstrate that mice bearing Ly-6(hi) DA3 tumors have a significantly higher burden of spontaneous pulmonary metastasis than mice bearing Ly-6(lo) DA3 tumors. Furthermore, the survival time of the former mice was significantly shorter than that of the latter ones. We further show that certain other members of the Ly-6 gene family such as Ly-6C.1 and Ly-6G.1 are coregulated with Ly-6E.1. This was shown to occur with respect to both DA3 cells as well as A3 tumor cells which are of fibroblast origin. However, these 2 cells differ with respect to regulation of Sca-2 (TSA1, another member of the Ly-6 family) expression on these cells. Levels of Sca-2 on A3 cells appear to be coregulated with Ly-6E.1 (i.e., Ly-6(hi) A3 cells express high levels of Sca-2 and Ly-6(lo) A3 cells express low levels of Sca-2). These 2 Ly-6 proteins were, however, not coregulated on DA3 cells. Both Ly-6(hi) as well as Ly-6(lo) DA3 cells express equal levels of Sca-2. Levels of Thy-1, another glycosylphosphatidylinositol (GPI)-anchored protein expressed by A3 tumor cells, were equally expressed by both Ly-6(hi) and Ly-6(lo) A3 tumor cells. Levels of Ly-6 (but not those of CD44) on A3 tumor cells were upregulated on cells from dense cultures but were not influenced by the position of the cells in the cell cycle. Stress conditions such as serum starvation or heat shock upregulated the expression of Ly-6 by the 2 types of tumor cells but did not induce apoptosis in these cells. The kinetics of the stress-dependent upregulation of Ly-6 expression differed, however, between the epithelial and fibroblastic tumor cells.

Abstract
Non immunohematopoietic murine tumor cells ectopically expressing Fc gamma RIIB1 (B1) were recently shown to express a higher tumorigenicity phenotype than cells not expressing this receptor. Utilizing a genetic approach we studied the possible contribution of a soluble form of B1 to tumor enhancement. A mutated form of the B1, lacking the cleavage site responsible for the generation of soluble B1 was produced using gene splicing by overlap extension PCR. A deletion confirmed by sequence analysis from 172 to 178 residues was generated. Stable transfectants expressed the B1 deleted form (B1 Delta) both as specific RNA and as a membrane protein receptor allowing a low level of ligand binding. The soluble form of B1 was undetectable in tissue culture supernatants of Bib transfected cells while it was present in supernatants of wild type B1-transfectants. Stable B1 Delta transfectants were significantly more tumorigenic than negative control transfectants. Tumor incidence was almost as high as that of intact B1 and lagged in the latency period before the appearance of palpable tumors. It is suggested that the soluble B1 has a minimal contribution to tumor enhancement.

Abstract
In previous studies non-lymphoid murine tumor cells were sorted by flow cytometry, into 2 subpopulations. The one expressed high levels of the T-cell activation protein Ly-6 A/E and the other low levels of this protein. High Ly-6 A/E expression was associated with very high tumorigenicity and metastatic phenotypes. Cells expressing low levels of this protein expressed a significantly reduced malignancy phenotype as compared to unsorted tumor populations. In view of its direct (or indirect) involvement in tumor progression we studied, in the present work, the regulation by microenvironmental factors of Ly-6 A/E expression on A3C polyoma-virus transformed cells. Ligation of membrane Ly-6 A/E by the corresponding monoclonal antibodies resulted in up-regulated expression of this protein. Similar results were obtained by exposing A3C cells to interferon-alpha. In contrast, exposing tumor cells to tumor necrosis factor-alpha or to the extracellular matrix protein laminin resulted in a down-regulation of Ly-6 A/E expression on these cells. These results provide an additional insight into the role microenvironmental factors might play in tumor progression.

Abstract
Murine Ly-6 is a molecule expressed by various cells, including several types of hematopoietic cells such as pluripotent stem cells, and activated T cells. Ly-6 is also expressed on tumor cells originating from a variety of tissues. Preliminary observations suggested that the expression of Ly-6A/E is up-regulated on highly tumorigenic variants of polyoma-virus(PyV)-transformed BALB/c 3T3 cells as compared with weakly tumorigenic variants. On the basis of these observations, we sorted PyV-transformed A3C cells or DA3 mammary adenocarcinoma cells into stable sub-populations expressing high or low levels of membrane or mRNA Ly-6A/E. In vivo studies indicated that the high-Ly-6A/E-expressing cells in both tumor systems expressed a considerably more malignant phenotype (higher efficiency in local tumor production as well as in lung colonization) than low-Ly-6A/E expressors. Since the high-Ly-6A/E expressors did not exhibit any growth advantage in vitro over low Ly-6A/E expressors, we concluded that interactions of the former cells with micro-environmental factors operating in vivo (e.g., Ly-6A/E ligands) conferred upon these cells a highly malignant phenotype. Apart from the difference in Ly-6A/E expression, no other phenotypic characteristics distinguished highly from weakly malignant tumor cells. Similarly to T cells, where antibodies to Ly-6 transduce (or co-transduce) a proliferative signal, antibodies to Ly-6A/E were found to transduce a mitogenic signal to high-Ly-6A/E-expressing tumor cells but not to low-Ly-6A/E expressors. Taken together, these results show that Ly-6A/E expression is directly or indirectly associated in vivo with a highly malignant phenotype of 2 types of non-lymphoid murine tumors.

Abstract
A fundamental new approach of deep drawing processes for uniform wall thickness is suggested and proved experimentally. It is based on imposition of a back-up fluid pressure which is prescheduled to vary with respect to the punch position during the drawing stroke in the hydroforming process. The formula for scheduling this fluid pressure path is generated via the plastic limit analysis and presented in terms of the geometry of the product, the work-hardening of the material, and the friction coefficient. It leads systematically to better results than empirical procedures reported in the current literature and industrial technical reports. Experiments in hydroforming sheets to cups and hemispheres performed on different materials (Al, Cu, and stainless steel) substantiate the improvement suggested. The associated overall punch load is overestimated (at most by 15 percent) with the unique feature of including Coulomb friction into the rigorous upper bound analysis.
