Abstract
CARD11-associated diseases are monogenic inborn errors of immunity involving immunodeficiency, predisposition to malignancy and immune dysregulation such as lymphoproliferation, inflammation, atopic and autoimmune manifestations. Defects in CARD11 can present as mutations that confer a complete or a partial loss of function (LOF) or contrarily, a gain of function (GOF) of the affected gene product. We report clinical characteristics, immunophenotypes and genotypes of 15 patients from our center presenting with CARD11-associated diseases. Index cases are pediatric patients followed in our immunology division who had access to next generation sequencing studies. Variant significance was defined by functional analysis in cultured cells transfected with a wild type and/or with mutated hCARD11 constructs. Cytoplasmic aggregation of CARD11 products was evaluated by immunofluorescence. Nine index patients with 9 unique heterozygous CARD11 variants were identified. At the time of the identification, 7 variants previously unreported required functional validation. Altogether, four variants showed a GOF effect as well a spontaneous aggregation in the cytoplasm, leading to B cell expansion with NF-κB and T cell anergy (BENTA) diagnosis. Additional four variants showing a LOF activity were considered as causative of CARD11-associated atopy with dominant interference of NF-kB signaling (CADINS). The remaining variant exhibited a neutral functional assay excluding its carrier from further analysis. Family segregation studies expanded to 15 individuals the number of patients presenting CARD11-associated disease. A thorough clinical, immunophenotypical, and therapeutic management evaluation was performed on these patients (5 BENTA and 10 CADINS). A remarkable variability of disease expression was clearly noted among BENTA as well as in CADINS patients, even within multiplex families. Identification of novel CARD11 variants required functional studies to validate their pathogenic activity. In our cohort BENTA phenotype exhibited a more severe and expanded clinical spectrum than previously reported, e.g., severe hematological and extra hematological autoimmunity and 3 fatal outcomes. The growing number of patients with dysmorphic facial features strengthen the inclusion of extra-immune characteristics as part of the CADINS spectrum. CARD11-associated diseases represent a challenging group of disorders from the diagnostic and therapeutic standpoint, especially BENTA cases that can undergo a more severe progression than previously described.

Abstract
Inherited bone marrow failure syndromes (IBMFSs) are a group of disorders typified by impaired production of 1 or several blood cell types. The telomere biology disorders dyskeratosis congenita (DC) and its severe variant, Høyeraal-Hreidarsson (HH) syndrome, are rare IBMFSs characterized by bone marrow failure, developmental defects, and various premature aging complications associated with critically short telomeres. We identified biallelic variants in the gene encoding the 5'-to-3' DNA exonuclease Apollo/SNM1B in 3 unrelated patients presenting with a DC/HH phenotype consisting of early-onset hypocellular bone marrow failure, B and NK lymphopenia, developmental anomalies, microcephaly, and/or intrauterine growth retardation. All 3 patients carry a homozygous or compound heterozygous (in combination with a null allele) missense variant affecting the same residue L142 (L142F or L142S) located in the catalytic domain of Apollo. Apollo-deficient cells from patients exhibited spontaneous chromosome instability and impaired DNA repair that was complemented by CRISPR/Cas9-mediated gene correction. Furthermore, patients' cells showed signs of telomere fragility that were not associated with global reduction of telomere length. Unlike patients' cells, human Apollo KO HT1080 cell lines showed strong telomere dysfunction accompanied by excessive telomere shortening, suggesting that the L142S and L142F Apollo variants are hypomorphic. Collectively, these findings define human Apollo as a genome caretaker and identify biallelic Apollo variants as a genetic cause of a hitherto unrecognized severe IBMFS that combines clinical hallmarks of DC/HH with normal telomere length.

Abstract
PURPOSE X-linked inhibitor of apoptosis protein (XIAP) deficiency, also known as the X-linked lymphoproliferative syndrome of type 2 (XLP-2), is a rare immunodeficiency characterized by recurrent hemophagocytic lymphohistiocytosis, splenomegaly, and inflammatory bowel disease. Variants in XIAP including missense, non-sense, frameshift, and deletions of coding exons have been reported to cause XIAP deficiency. We studied three young boys with immunodeficiency displaying XLP-2-like clinical features. No genetic variation in the coding exons of XIAP was identified by whole-exome sequencing (WES), although the patients exhibited a complete loss of XIAP expression. METHODS Targeted next-generation sequencing (NGS) of the entire locus of XIAP was performed on DNA samples from the three patients. Molecular investigations were assessed by gene reporter expression assays in HEK cells and CRISPR-Cas9 genome editing in primary T cells. RESULTS NGS of XIAP identified three distinct non-coding deletions in the patients that were predicted to be driven by repetitive DNA sequences. These deletions share a common region of 839 bp that encompassed the first non-coding exon of XIAP and contained regulatory elements and marks specific of an active promoter. Moreover, we showed that among the 839 bp, the exon was transcriptionally active. Finally, deletion of the exon by CRISPR-Cas9 in primary cells reduced XIAP protein expression. CONCLUSIONS These results identify a key promoter sequence contained in the first non-coding exon of XIAP. Importantly, this study highlights that sequencing of the non-coding exons that are not currently captured by WES should be considered in the genetic diagnosis when no variation is found in coding exons.

Abstract
The noncanonical NF-κB pathway is implicated in diverse biological and immunological processes. Monoallelic C-terminus loss-of-function and gain-of-function mutations of NFKB2 have been recently identified as a cause of immunodeficiency manifesting with common variable immunodeficiency (CVID) or combined immunodeficiency (CID) phenotypes. Herein we report a family carrying a heterozygous nonsense mutation in NFKB2 (c.809G > A, p.W270*). This variant is associated with increased mRNA decay and no mutant NFKB2 protein expression, leading to NFKB2 haploinsufficiency. Our findings demonstrate that bona fide NFKB2 haploinsufficiency, likely caused by mutant mRNA decay and protein instability leading to the transcription and expression of only the wild-type allele, is associated with clinical immunodeficiency, although with incomplete clinical penetrance. Abnormal B cell development, hypogammaglobulinemia, poor antibody response, and abnormal noncanonical (but normal canonical) NF-κB pathway signaling are the immunologic hallmarks of this disease. This adds a third allelic variant to the pathophysiology of NFKB2-mediated immunodeficiency disorders.

Abstract
WHIM syndrome is a primary autosomal dominant immuno deficiency due to CXCR4 mutations characterized by mucocutaneous warts, hypogammaglobulinemia, recurrent bacterial infections and myelokathesis. Treatment consists in prophylactic antibiotics, immunoglobulin replacement and granulocyte or granulocyte/monocyte colony stimulating factors. We present the case of a 21 year old woman who showed leukopenia at 10 months of age and one year later multiple infections with hypogammaglobulinemia requiring intravenous immunoglobulin. During follow up she developed chronic neutropenia. A bone marrow aspiration showed increased myeloid series with predominance of immature elements. On the basis of infections, low levels of IgG, IgA, IgM and lymphopenia with absent memory B cells, a diagnosis of common variable immunodeficiency was made. She started intravenous immunoglobulin replacement and prophylactic antibiotics. At age 20, small warts in hands that progressed to forearms, knees, abdomen and face were recorded. CXCR4 gene sequencing was done detecting a heterozygous p.Arg334STOP mutation, confirming WHIM syndrome. This disease is infrequent and difficult to diagnose.

Abstract
Abstract
Monogenic causes for serious manifestations of common allergic disease inform our mechanistic understanding of the pathogenesis of atopy. However, infections and other syndromic phenotypes often accompany such disorders. We performed next-generation sequencing on a cohort of patients with severe atopic dermatitis with evidence of familial inheritance, regardless of comorbidities. We discovered 9 individuals from 5 families harboring distinct, novel heterozygous mutations in CARD11, a lymphocyte scaffolding protein that facilitates NF-κB and mTOR signaling following antigen receptor (AgR) engagement. Significant infections beyond the skin, and non-immunologic comorbidities, were documented in some but not all patients. Improvement of skin and infectious history were noted in the majority of the patients. Each CARD11 mutant exhibited attenuated AgR-driven signaling to NF-κB and mTORC1, and dominantly interfered with the ability of WT CARD11 to activate these pathways in transfected T cell lines. Primary patient T cells also showed defects in AgR-induced activation of NF-κB and mTORC1, which is critical for promoting Th1 and preventing Th2 responses. Impaired proliferation, mTORC1 signaling and IFN-γ production were partially rescued by supplementing with excess glutamine, which requires CARD11 for import into T cells. In contrast to B cell lymphoproliferative disease associated with gain-of-function CARD11 mutations, and severe combined immunodeficiency associated with null CARD11 mutations, our new findings indicate single hypomorphic mutations in CARD11 can cause potentially correctable cellular defects that lead to severe atopy.

Abstract
BACKGROUND Germline heterozygous mutations in human signal transducer and activator of transcription 1 (STAT1) can cause loss of function (LOF), as in patients with Mendelian susceptibility to mycobacterial diseases, or gain of function (GOF), as in patients with chronic mucocutaneous candidiasis. LOF and GOF mutations are equally rare and can affect the same domains of STAT1, especially the coiled-coil domain (CCD) and DNA-binding domain (DBD). Moreover, 6% of patients with chronic mucocutaneous candidiasis with a GOF STAT1 mutation have mycobacterial disease, obscuring the functional significance of the identified STAT1 mutations. Current computational approaches, such as combined annotation-dependent depletion, do not distinguish LOF and GOF variants. OBJECTIVE We estimated variations in the CCD/DBD of STAT1. METHODS We mutagenized 342 individual wild-type amino acids in the CCD/DBD (45.6% of full-length STAT1) to alanine and tested the mutants for STAT1 transcriptional activity. RESULTS Of these 342 mutants, 201 were neutral, 30 were LOF, and 111 were GOF mutations in a luciferase assay. This assay system correctly estimated all previously reported LOF mutations (100%) and slightly fewer GOF mutations (78.1%) in the CCD/DBD of STAT1. We found that GOF alanine mutants occurred at the interface of the antiparallel STAT1 dimer, suggesting that they destabilize this dimer. This assay also precisely predicted the effect of 2 hypomorphic and dominant negative mutations, E157K and G250E, in the CCD of STAT1 that we found in 2 unrelated patients with Mendelian susceptibility to mycobacterial diseases. CONCLUSION The systematic alanine-scanning assay is a useful tool to estimate the GOF or LOF status and the effect of heterozygous missense mutations in STAT1 identified in patients with severe infectious diseases, including mycobacterial and fungal diseases.

Abstract
BACKGROUND Common variable immunodeficiency (CVID) is a heterogeneous syndrome characterized by impaired immunoglobulin production and usually presents with a normal quantity of peripheral B cells. Most attempts aiming to classify these patients have mainly been focused on T- or B-cell phenotypes and their ability to produce protective antibodies, but it is still a major challenge to find a suitable classification that includes the clinical and immunologic heterogeneity of these patients. OBJECTIVE In this study we evaluated the late stages of B-cell differentiation in a heterogeneous population of patients with pediatric-onset CVID to clinically correlate and assess their ability to perform somatic hypermutation (SHM), class-switch recombination (CSR), or both. METHODS We performed a previously reported assay, the restriction enzyme hotspot mutation assay (IgκREHMA), to evaluate in vivo SHM status. We amplified switch regions from genomic DNA to investigate the quality of the double-strand break repairs in the class-switch recombination process in vivo. We also tested the ability to generate immunoglobulin germline and circle transcripts and to upregulate the activation-induced cytidine deaminase gene through in vitro T-dependent and T-independent stimuli. RESULTS Our results showed that patients could be classified into 2 groups according to their degree of SHM alteration. This stratification showed a significant association between patients of group A, severe alteration, and the presence of noninfectious complications. Additionally, 60% of patients presented with increased microhomology use at switched regions. In vitro activation revealed that patients with CVID behaved heterogeneously in terms of responsiveness to T-dependent stimuli. CONCLUSIONS The correlation between noninfectious complications and SHM could be an important tool for physicians to further characterize patients with CVID. This categorization would help to improve elucidation of the complex mechanisms involved in B-cell differentiation pathways.

Abstract
AIM We analyzed data from 71 patients with chronic granulomatous disease (CGD) with a confirmed genetic diagnosis, registered in the online Latin American Society of Primary Immunodeficiencies (LASID) database. RESULTS Latin American CGD patients presented with recurrent and severe infections caused by several organisms. The mean age at disease onset was 23.9 months, and the mean age at CGD diagnosis was 52.7 months. Recurrent pneumonia was the most frequent clinical condition (76.8%), followed by lymphadenopathy (59.4%), granulomata (49.3%), skin infections (42%), chronic diarrhea (41.9%), otitis (29%), sepsis (23.2%), abscesses (21.7%), recurrent urinary tract infection (20.3%), and osteomyelitis (15.9%). Adverse reactions to bacillus Calmette-Guérin (BCG) vaccination were identified in 30% of the studied Latin American CGD cases. The genetic diagnoses of the 71 patients revealed 53 patients from 47 families with heterogeneous mutations in the CYBB gene (five novel mutations: p.W361G, p.C282X, p.W483R, p.R226X, and p.Q93X), 16 patients with the common deletion c.75_76 del.GT in exon 2 of NCF1 gene, and two patients with mutations in the CYBA gene. CONCLUSION The majority of Latin American CGD patients carry a hemizygous mutation in the CYBB gene. They also presented a wide range of clinical manifestations most frequently bacterial and fungal infections of the respiratory tract, skin, and lymph nodes. Thirty percent of the Latin American CGD patients presented adverse reactions to BCG, indicating that this vaccine should be avoided in these patients.

Abstract
Wiskott-Aldrich syndrome was first reported clinically in 1937, and in 1954 the classic triad was identified: eccema, recurrent infections and thrombocytopenia with an X-linked transmission. Its incidence is estimated at 1 to 10 in one million live births per year. Wiskott Aldrich syndrome is caused by mutations in a gene in the short arm of chromosome X that encodes the Wiskott-Aldrich syndrome protein (WASp), which identification and sequencing was first performed in 1994, and since then about 300 mutations have been reported. This paper describes the case of a boy with Wiskott-Aldrich syndrome, with clinical and genetic diagnosis, with a considerable diagnostic delay attributable to an atypical presentation misdiagnosed as immune thrombocytopenia.

Abstract
El síndrome de Wiskott Aldrich fue descrito en 1937 y en 1954 se identificó su tríada característica: eccema, infecciones recurrentes y trombocitopenia, con herencia ligada al cromosoma X. Su incidencia se calcula en 1 a 10 por cada millón de recién nacidos vivos por año. Su causa es la mutación del gen localizado en el brazo corto del cromosoma X, que codifica la proteína del síndrome Wiskott-Aldrich (WASp), cuya identificación y secuenciación se realizan desde 1994, lo que ha permitido describir al menos 300 defectos genéticos. Comunicamos un caso de síndrome de Wiskott-Aldrich con diagnóstico clínico y genético, tipo nonsense Q203X, en el exón 7, en un preescolar con ausencia de eccema.

Abstract
Mutations in the transmembrane activator and calcium-modulating cyclophilin ligand interactor (TACI) were previously found to be associated with hypogammaglobulinemia in humans. It has been shown that proliferation inducing ligand (APRIL) elicits class switch recombination (CSR) by inducing recruitment of MyD88 to a TACI highly conserved cytoplasmic domain (THC). We have identified a patient with hypogammaglobulinemia carrying a missense mutation (S231R) predicted to affect the THC. Aiming to evaluate the relevance of this novel mutation of TACI in CSR induction, we tested the ability of TACI, TLR9, or/and CD40 ligands to trigger CSR in naive B cells and B-cell lines carrying S231R. IgG secretion was impaired when triggered by TACI or/and TLR9 ligands on S231R-naive B cells. Likewise, these stimuli induced less expression of activation-induced cytidine deaminase, I(γ)1-C(μ), and I(γ)1-C(μ), while induction by optimal CD40 stimulation was indistinguishable from controls. These cells also showed an impaired cooperation between TACI and TLR9 pathways, as well as a lack of APRIL-mediated enhancement of CD40 activation in suboptimal conditions. Finally, after APRIL ligation, S231R-mutated TACI failed to colocalize with MyD88. Collectively, these results highlight the requirement of an intact MyD88-binding site in TACI to trigger CSR.

Abstract
Wiskott Aldrich syndrome (WAS) is an X-linked primary immunodeficiency, associated with WASP gene mutation that causes severe immunological abnormalities and alterations in platelet function. A seven year old male patient with WASP, began with acute abdominal pain, fever and knee swelling. The diagnosis of septic arthritis was made, and he was treated with broad-spectrum antibiotics and human gammaglobulin. During treatment he presented digestive tract bleeding with hypovolemic shock; after 72 hours palpable purpura in upper and lower extremities appeared. Then Henoch-Schönlein purpura with abdominal vasculitis was suspected, and later confirmed by histopathology. Methylprednisolone pulses were initiated, showing improvement within 24 hours. The patient had a severe inflammatory reaction, caused by a serious infectious disease, but the clinical evolution suggested an autoimmune disease such as Henoch-Schönlein purpura. Up to 20% of patients with WAS have autoimmune manifestations of vasculitis. An early diagnosis of autoimmunity in WAS is important for a favorable clinical outcome.

Abstract
Common variable immunodeficiency (CVID) is a heterogeneous syndrome characterized by impaired immunoglobulin production. Mutations in the gene encoding TACI (TNFRSF13B) were previously found to be associated with CVID. Previous studies have identified a variety of sequence variants in TACI where A181E and C104R were the most common, with variable frequencies in different ethnic populations. So far, no mutations were identified in the recently reported "TACI highly conserved" (THC) cytoplasmic domain, important for the induction of class switch recombination. Our study evaluated immunological and clinical data on a cohort of 28 Argentinean pediatric CVID patients and allowed the identification of two novel mutations in TNFRSF13B, including one, S231R, affecting the highly conserved THC domain. In contrast, none of the patients presented with A181E and C104R mutations.

Abstract
INTRODUCTION Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease with major diagnostic and therapeutic difficulties, basically comprising two different conditions: primary and secondary forms. Recent advances regarding molecular diagnosis may be useful to distinguish from one another, especially in sporadic cases starting in early infancy. MATERIALS AND METHODS In this report, we evaluated three Argentinean patients with clinical suspicion of HLH, but without family history. We excluded mutations in the perforin gene but identified in the three patients a novel homozygous deletion (c. 581_584delTGCC; p.Leu194ProfsX2) in the gene-encoding syntaxin 11 (STX11), causing a premature termination codon. RESULTS AND CONCLUSION Each parent from the three unrelated families resulted heterozygous for this deletion confirming the diagnosis of familial hemophagocytic lymphohistiocytosis type 4. Patients shared the same single-nucleotide polymorphism profile in STX11 gene, and genotyping at ten microsatellites surrounding this gene support the presence of a single-haplotype block carrying the novel mutation.

Abstract
CD40 ligand (CD40L) deficiency is an X-linked combined immunodeficiency characterized by impaired class switch recombination. We analyzed clinical and molecular findings in 11 Argentinian patients from seven unrelated families. The mean age at onset of symptoms was 1.1 years (0.5-3.0 years) and the 10 alive patients have a median age of 17 years. We identified two nonsense mutations, including R11X reported as a "hypomorphic" defect, four missense mutations, and one point deletion. Although R11X was associated herein with parvovirus B19-anemia and higher Igs levels as previously described, histoplasmosis and Pneumocystis jiroveci pneumonia were also present. Other so-called "milder" mutation, T254M, was present in three related patients clinically and immunologically undistinguishable from the rest of the cohort. Furthermore, 10 of the 11 patients, having heterogeneous mutations, never had persistent neutropenia, none presented Cryptosporidium sp. infection nor developed liver-biliary tract disease, highlighting the debatable concept of "milder" mutations.

Abstract
BACKGROUND Post-transplant lymphoproliferative disease (PTLD) is a frequent and severe Epstein-Barr virus (EBV)-associated complication in transplant recipients that is caused by suppression of T-cell function. OBJECTIVE Evaluation of the diagnostic value of EBV DNA load in non-fractionated whole blood samples (n = 297) from 110 pediatric transplant patients by real-time PCR. RESULTS AND CONCLUSIONS Patients with PTLD had a median viral load of 1.08 x 10(5) copies/ml blood (n = 24), which was significantly higher compared with patients without PTLD (median: 50 copies/ml blood, n = 273, P < 0.0001). From receiver operating characteristic (ROC) curve analysis we obtained a cut-off value of 6215 copies/ml blood with a sensitivity of 95.8%, specificity of 71.4%, negative predictive value (NPV) of 99.5% and positive predictive value (PPV) of 22.8%. Thus, real-time PCR proved to be more useful in ruling out than in indicating the presence of PTLD. Further analysis showed that patients without PTLD but developing a post-transplant EBV-primary infection had associated high viral loads that were indistinguishable from those of the PTLD group (statistically not significant). Similarly, the presence of clinical symptoms of disease in patients without PTLD was associated with higher viral loads than in patients that were asymptomatic (P < 0.0001), but the difference was much less significant when compared with the PTLD group of patients (P = 0.0391). These patients who had a high viral load may benefit from a close follow-up of the viral burden.

Abstract
The block in differentiation from pro-B to pre-B cells results in a selective defect in the humoral immune response characteristic of human X-linked agammaglobulinemia (XLA). Mutations of Bruton tyrosine kinase (BTK) gene have been identified as the cause of XLA. Mutation detection is the most reliable method for making a definitive diagnosis, except when clinical and laboratory findings are distinctive and coupled with history of X-linked inheritance. To provide a definitive diagnosis to 40 families incorporated in the Argentinian Primary Immunodeficiencies Registry we analysed the BTK gene by SSCP analysis as screening method for XLA, followed by direct sequencing. The molecular defect was localized in 45 patients from 34 unrelated families. From the 34 independent mutations identified, 16 were previously undescribed, 31 were unique mutations, 22 were exonic single nucleotide changes (16 missense and 6 nonsense) and four intronic mutations. Because five families had clinical, immunological and inheritance data sufficient for a definitive diagnosis, our study allowed 37 patients from 29 families previously categorized probable/ possible XLA, have now definitive diagnosis leading to appropriate genetic counseling.

Abstract
Wiskott-Aldrich syndrome (WAS), is an X-linked immunodeficiency disease caused by mutations of the WAS protein (WASP) gene, characterized by thrombocytopenia, eczema and recurrent infections. X-linked thrombocytopenia (XLT) is a milder form with only platelet abnormalities. Cumulative mutation data have revealed that WASP genotypes are highly variable among WAS patients. By SSCP analysis, we determined the location of the mutation in 23 WAS patients from 17 unrelated families with variable clinical phenotypes. Direct sequence analysis of genomic DNA showed 9 novel mutations (Q52H, G70W, 393del7, Ex 7 Ex11del, IVS 8+1G-->C, 925delG, 959ins38, 1380del8, and IVS 2+2T-->C) and 8 known mutations distributed throughout the WAS gene. This is the first report of WAS gene mutations from a Latin American country.

Abstract
The protein tyrosine kinases (PTK) are implicated in cell proliferation processes. Furthermore, a number of viral oncogenes encode constitutively active variants of tyrosine kinases and several growth factor receptors possess intrinsic tyrosine kinase activity. The regulation and biological function of the kinase activity of Src family PTK are not yet well established. However, three of these kinases (src, yes and fgr) have been initially identified as products of viral oncogenes and a fourth (lck) is activated and overexpressed in certain lymphomas. In fact, several biological systems implicate and early and transient activation of Scr family PTK.

Abstract
Abstract
The zeta-subunit of the TCR binds GTP and is a well characterized substrate for a TCR-activated tyrosine kinase. To examine the possible coupling of GTP-binding to zeta with TCR-mediated signal transduction, a mutant (termed J32-3.2) of the T cell line Jurkat (J32) was used. Anti-TCR/CD3 stimulation of the TCR/CD3+ J32-3.2 cells resulted in a weak stimulation of both the phosphatidyl inositol and tyrosine kinase signal transduction pathways, as measured by changes in the level of free intracellular calcium, tyrosine phosphorylation of TCR-zeta, CD3-epsilon and ZAP-70, p56lck, or p59fyn tyrosine kinase activity and IL-2 gene activation. The impaired responsiveness of J32-3.2 cells to anti-TCR/CD3 mAb correlated with a low basal level of GTP-binding to zeta. Furthermore, in J32-3.2 cells TCR activation by antibody ligation caused a weaker increase in GTP-binding to the zeta-chain, as compared with that of wild-type J32 cells, which indicates for the first time that GTP-binding to zeta can be modulated by extracellular signals and suggest that the role of GTP-binding to zeta is to couple the TCR to intracellular signal transduction mechanisms.

Abstract
T cell activation by triggering the T cell receptor (TcR)-CD3 complex leads to a dramatic increase in tyrosine phosphorylation of multiple cellular proteins. To date, there has been no direct evidence on the identity of the tyrosine kinase activity implicated in this signaling pathway. In this study, we demonstrate that activation of human T cells with anti-CD3 monoclonal antibody increases tyrosine kinase activity of p56lck. This extends our previous findings which demonstrated the involvement of p56lck kinase activity in the CD2 signal transduction pathway. The results from peripheral blood lymphocytes and Jurkat cell line showed in both cases an early and transient change in the specific activity of p56lck, followed by a shift to a higher apparent molecular mass. Therefore, to test directly the role of TcR-CD3 in CD2-induced activation of p56lck, we utilized mutant variants of the Jurkat cell line lacking in cell surface TcR-CD3. We found that cell surface expression of TcR-CD3 is not required for the activation of p56lck via CD2 but is necessary for the appearance of the reduced-electrophoretic-mobility form of p56lck observed after CD2 triggering. By isolating CD45- mutants from Jurkat cells, we observed that surface expression of the tyrosine phosphatase CD45 is required in order to increase p56lck activity following CD2 stimulation, while CD4-induced activation of the kinase remained unchanged. These data provide evidence for a specific functional linkage between CD2 and p56lck, in which CD45 may play an essential role.

Abstract
Abstract
Incubation of the human T cells, Jurkat, with two sets of activating anti-CD2 mAb (T11(2) + T11(3), D66 + T11(1)) induced delocalization of p56lck and CD2 receptors from the plasma membrane and increased the tyrosine kinase activity of p56lck. The anti-CD2 mAb combination (T11(2) + T11(3)) that produced the most rapid increase in p56lck kinase activity also induced the most rapid delocalization of the kinase. In stimulated cells, both p56lck and CD2 receptors are detected in cytoplasmic vesicles. The internalization of p56lck in endocytic vesicles was established by confocal microscopy. By double staining it was shown that only part of the p56lck colocalized with the internalized CD2 receptor suggesting distinct sorting processes. Internalization of p56lck appeared to be specific of CD2 stimulation as: 1) in Jurkat cells triggered with an anti-CD3 mAb, p56lck was not internalized whereas CD3 receptors were completely endocytosed; 2) when cells were stimulated via CD4, the kinase and CD4 receptors remained associated with the plasma membrane. In addition, internalization of p56lck upon stimulation of CD2 receptors was not modified in CD2+/CD3-Jurkat cells indicating that CD3 is not involved in this process. The identification of different subcellular localizations of p56lck in resting and stimulated T cells should represent an important step in the definition of its functional activity.

Abstract
An early biochemical event associated with T cell activation is tyrosine phosphorylation. We have previously shown that p56lck, a lymphocyte-specific protein tyrosine kinase, is hyperphosphorylated on serine and tyrosine residues 15 minutes after activation via CD2 with a concomitant shift to a higher molecular mass. We now demonstrate that the tyrosine kinase activity of p56lck is increased within seconds following CD2 triggering. This activity decreases thereafter correlating with the appearance of changes in phosphorylation previously described. These results suggest that p56lck may play an important role in the CD2 activation pathway.

Abstract
p56lck is a src related lymphocyte specific tyrosine protein kinase which undergoes specific changes during T-cell activation, particularly the appearance of slow migrating forms. To analyze these forms, LSTRA cells were treated with vanadate. This resulted in increased phosphorylation of p56lck with the appearance of slow migrating forms. Renaturation of the p56lck bands after gel migration showed that vanadate mostly increased the activity of the lower band of p56lck. The upper bands had a reduced specific activity. In addition, the upper bands from vanadate treated cells displayed additional phosphorylated sites.

Abstract
Human T cells can be activated and induced to proliferate through either the antigen-specific receptor complex (TcR-CD3) or the CD2 surface molecule. Following stimulation, both serine and tyrosine phosphorylation of cellular protein have been demonstrated to occur. p56lck, a protein tyrosine kinase associated to the inner face of the plasma membrane, is almost exclusively expressed in lymphoid cells, especially T cells. Within minutes after activation of a human T cell-derived line (Jurkat) via stimulation of either the TcR-CD3 complex or the CD2 glycoprotein, we observed a hyperphorphosylation of p56lck. A concomitant shift to a higher molecular weight in sodium dodecyl sulfate-polyacrylamide gel was also observed. Similar changes were obtained with phorbol 12-myristate 13-acetate. Tryptic phosphopeptide analysis of the hyperphosphorylated form of p56lck yielded new phosphorylated sites in serine residues and an increased tyrosine phosphorylation. These results suggest that p56lck may be intimately connected to the signaling pathway in T cell activation.

Abstract
Recent studies have suggested a role for extracellular ATP. In this report we show that extracellular labelled ATP crosses the plasma membrane of intact lymphoma cells and peripheral blood lymphocytes and phosphorylates p56lck a tyrosine protein kinase specific of lymphoid cells. Two other phosphoproteins of 92Kd and 35Kd become detectable on alkali treated gels. Phosphorylation occurs within minutes following addition of ATP. ATP, GTP, ADP and an ATP analog prevent phosphorylation but not AMP nor Pi; trypsinization of cells abolishes labelling. The possible involvement of P2 purinergic receptors is discussed.

Abstract
Phosphoproteins phosphorylated in vivo were examined in resting and thrombin-activated human blood platelets. Thrombin-stimulation resulted in an overall increase in labeled proteins containing phosphotyrosine. The most prominent was a protein of 60 Kd. By electroblotting, the 60 Kd protein was identified as the pp60c-src, the normal cellular homolog of the transforming protein of Rous sarcoma virus. We have examined the intracellular distribution of the pp60c-src within platelets. Use of immunoprecipitation and electrotransfer to study isolated membranes, alpha-granules, lysosomes, and dense granules (also termed dense bodies) revealed that pp60c-src was highly enriched in dense bodies. In view of the prominent role of these granules in platelet function, We postulate that protein phosphorylation by activated pp60c-src is involved in early steps of platelet activation.
