Abstract
Cancer remains one of the leading causes of mortality worldwide, leading to increased interest in utilizing immunotherapy strategies for better cancer treatments. In the past decade, CD103+ T cells have been associated with better clinical prognosis in patients with cancer. However, the specific immune mechanisms contributing toward CD103-mediated protective immunity remain unclear. Here, we show an unexpected and transient CD61 expression, which is paired with CD103 at the synaptic microclusters of T cells. CD61 colocalization with the T cell antigen receptor further modulates downstream T cell antigen receptor signaling, improving antitumor cytotoxicity and promoting physiological control of tumor growth. Clinically, the presence of CD61+ tumor-infiltrating T lymphocytes is associated with improved clinical outcomes, mediated through enhanced effector functions and phenotype with limited evidence of cellular exhaustion. In conclusion, this study identified an unconventional and transient CD61 expression and pairing with CD103 on human immune cells, which potentiates a new target for immune-based cellular therapies.

Abstract
Understanding clonal evolution and cancer development requires experimental approaches for characterizing the consequences of somatic mutations on gene regulation. However, no methods currently exist that efficiently link high-content chromatin accessibility with high-confidence genotyping in single cells. To address this, we developed Genotyping with the Assay for Transposase-Accessible Chromatin (GTAC), enabling accurate mutation detection at multiple amplified loci, coupled with robust chromatin accessibility readout. We applied GTAC to primary acute myeloid leukemia, obtaining high-quality chromatin accessibility profiles and clonal identities for multiple mutations in 88% of cells. We traced chromatin variation throughout clonal evolution, showing the restriction of different clones to distinct differentiation stages. Furthermore, we identified switches in transcription factor motif accessibility associated with a specific combination of driver mutations, which biased transformed progenitors toward a leukemia stem cell-like chromatin state. GTAC is a powerful tool to study clonal heterogeneity across a wide spectrum of pre-malignant and neoplastic conditions.

Abstract
Most existing studies characterizing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific T cell responses are peptide based. This does not allow evaluation of whether tested peptides are processed and presented canonically. In this study, we use recombinant vaccinia virus (rVACV)-mediated expression of SARS-CoV-2 spike protein and SARS-CoV-2 infection of angiotensin-converting enzyme (ACE)-2-transduced B cell lines to evaluate overall T cell responses in a small cohort of recovered COVID-19 patients and uninfected donors vaccinated with ChAdOx1 nCoV-19. We show that rVACV expression of SARS-CoV-2 antigen can be used as an alternative to SARS-CoV-2 infection to evaluate T cell responses to naturally processed spike antigens. In addition, the rVACV system can be used to evaluate the cross-reactivity of memory T cells to variants of concern (VOCs) and to identify epitope escape mutants. Finally, our data show that both natural infection and vaccination could induce multi-functional T cell responses with overall T cell responses remaining despite the identification of escape mutations.

Abstract
NP105-113-B*07:02-specific CD8+ T cell responses are considered among the most dominant in SARS-CoV-2-infected individuals. We found strong association of this response with mild disease. Analysis of NP105-113-B*07:02-specific T cell clones and single-cell sequencing were performed concurrently, with functional avidity and antiviral efficacy assessed using an in vitro SARS-CoV-2 infection system, and were correlated with T cell receptor usage, transcriptome signature and disease severity (acute n = 77, convalescent n = 52). We demonstrated a beneficial association of NP105-113-B*07:02-specific T cells in COVID-19 disease progression, linked with expansion of T cell precursors, high functional avidity and antiviral effector function. Broad immune memory pools were narrowed postinfection but NP105-113-B*07:02-specific T cells were maintained 6 months after infection with preserved antiviral efficacy to the SARS-CoV-2 Victoria strain, as well as Alpha, Beta, Gamma and Delta variants. Our data show that NP105-113-B*07:02-specific T cell responses associate with mild disease and high antiviral efficacy, pointing to inclusion for future vaccine design.

Abstract
The development of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines and therapeutics will depend on understanding viral immunity. We studied T cell memory in 42 patients following recovery from COVID-19 (28 with mild disease and 14 with severe disease) and 16 unexposed donors, using interferon-γ-based assays with peptides spanning SARS-CoV-2 except ORF1. The breadth and magnitude of T cell responses were significantly higher in severe as compared with mild cases. Total and spike-specific T cell responses correlated with spike-specific antibody responses. We identified 41 peptides containing CD4+ and/or CD8+ epitopes, including six immunodominant regions. Six optimized CD8+ epitopes were defined, with peptide-MHC pentamer-positive cells displaying the central and effector memory phenotype. In mild cases, higher proportions of SARS-CoV-2-specific CD8+ T cells were observed. The identification of T cell responses associated with milder disease will support an understanding of protective immunity and highlights the potential of including non-spike proteins within future COVID-19 vaccine design.

Abstract
COVID-19 is an ongoing global crisis in which the development of effective vaccines and therapeutics will depend critically on understanding the natural immunity to the virus, including the role of SARS-CoV-2-specific T cells. We have conducted a study of 42 patients following recovery from COVID-19, including 28 mild and 14 severe cases, comparing their T cell responses to those of 16 control donors. We assessed the immune memory of T cell responses using IFNγ based assays with overlapping peptides spanning SARS-CoV-2 apart from ORF1. We found the breadth, magnitude and frequency of memory T cell responses from COVID-19 were significantly higher in severe compared to mild COVID-19 cases, and this effect was most marked in response to spike, membrane, and ORF3a proteins. Total and spike-specific T cell responses correlated with the anti-Spike, anti-Receptor Binding Domain (RBD) as well as anti-Nucleoprotein (NP) endpoint antibody titre (p<0.001, <0.001 and =0.002). We identified 39 separate peptides containing CD4 + and/or CD8 + epitopes, which strikingly included six immunodominant epitope clusters targeted by T cells in many donors, including 3 clusters in spike (recognised by 29%, 24%, 18% donors), two in the membrane protein (M, 32%, 47%) and one in the nucleoprotein (Np, 35%). CD8+ responses were further defined for their HLA restriction, including B*4001-restricted T cells showing central memory and effector memory phenotype. In mild cases, higher frequencies of multi-cytokine producing M- and NP-specific CD8 + T cells than spike-specific CD8 + T cells were observed. They furthermore showed a higher ratio of SARS-CoV-2-specific CD8 + to CD4 + T cell responses. Immunodominant epitope clusters and peptides containing T cell epitopes identified in this study will provide critical tools to study the role of virus-specific T cells in control and resolution of SARS-CoV-2 infections. The identification of T cell specificity and functionality associated with milder disease, highlights the potential importance of including non-spike proteins within future COVID-19 vaccine design.

Abstract
Background: Cancer patients often display dysfunctional antitumor T-cell responses. Because noteworthy benefits of immune checkpoint pathway blockade, such as programmed cell death protein 1 (PD-1) inhibitors, have been achieved in multiple advanced cancers, the next critical question is which mono-blockade or combinatorial blockade regimens may reinvigorate antitumor T-cell immunity in those cancer patients while limiting immune-related adverse effects. Method: This study recruited, in total, 172 primary cancer patients (131 were blood-tumor-matched patients) who were treatment-naïve prior to the surgeries or biopsies covering the eight most prevalent types of cancer. With access to fresh surgical samples, this study simultaneously investigated the ex vivo expression level of eight known immune checkpoint receptors [PD-1, cytotoxic T-lymphocyte antigen-4 [CTLA-4], T-cell immunoglobulin and mucin-domain containing-3 [Tim-3], 2B4, killer cell lectin like receptor G1 [KLRG-1], TIGIT, B- and T-lymphocyte attenuator [BTLA], and CD160] on tumor-infiltrating T cells (TILs) and paired circulating T cells in blood from a 131-patient cohort. Results: We found increased an expression of PD-1 and Tim-3 but a decreased expression of BTLA on TILs when compared with peripheral blood from multiple types of cancer. Moreover, our co-expression analysis of key immune checkpoint receptors delineates "shared" subsets as PD-1+Tim-3+TIGIT+2B4+KLRG-1-CTLA-4- and PD-1+TIGIT+2B4+Tim-3-KLRG-1-CTLA-4- from bulk CD8 TILs. Furthermore, we found that a higher frequency of advanced differentiation stage T cells (CD27-CCR7-CD45RA-) among the "shared" subset (PD-1+Tim-3+TIGIT+2B4+KLRG-1-CTLA-4-) in bulk CD8 TILs was associated with poorly differentiated cancer type in cervical cancer patients. Conclusions: To our knowledge, our study is the first comprehensive analysis of key immune checkpoint receptors on T cells in treatment-naïve, primary cancer patients from the eight most prevalent types of cancer. These findings might provide useful information for future design of mono-blockade/combinatorial blockades and/or genetically modified T-cell immunotherapy.

Abstract
Within the ruminant system, several possibilities exist to generate dendritic cells migrating out from the tissue into the regional draining lymph nodes as afferent lymph dendritic cells (ALDCs). Here, we analyzed toll-like receptor (TLR) 1-10 mRNA expression by using quantitative real-time PCR in highly purified subsets of bovine ALDC. As TLR expression may be influenced by pathogens or vaccines and their adjuvant, it is necessary to understand what TLRs are expressed in a steady-state system to elucidate specific differences and to potentially optimize targeted vaccines. In this study, we have assessed the TLR expression profiles of the four main bovine ALDC subsets [cDC1 and cDC2 (subsets 2-4)]. We demonstrate differences in TLR expression between the four subsets that may reflect the ability of these cells to respond to different pathogens or to respond to adjuvants.

Abstract
Induced pluripotent stem cell (iPSC)-derived cortical neurons potentially present a powerful new model to understand corticogenesis and neurological disease. Previous work has established that differentiation protocols can produce cortical neurons, but little has been done to characterize these at cellular resolution. In particular, it is unclear to what extent in vitro two-dimensional, relatively disordered culture conditions recapitulate the development of in vivo cortical layer identity. Single-cell multiplex reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR) was used to interrogate the expression of genes previously implicated in cortical layer or phenotypic identity in individual cells. Totally, 93.6% of single cells derived from iPSCs expressed genes indicative of neuronal identity. High proportions of single neurons derived from iPSCs expressed glutamatergic receptors and synaptic genes. And, 68.4% of iPSC-derived neurons expressing at least one layer marker could be assigned to a laminar identity using canonical cortical layer marker genes. We compared single-cell RNA-seq of our iPSC-derived neurons to available single-cell RNA-seq data from human fetal and adult brain and found that iPSC-derived cortical neurons closely resembled primary fetal brain cells. Unexpectedly, a subpopulation of iPSC-derived neurons co-expressed canonical fetal deep and upper cortical layer markers. However, this appeared to be concordant with data from primary cells. Our results therefore provide reassurance that iPSC-derived cortical neurons are highly similar to primary cortical neurons at the level of single cells but suggest that current layer markers, although effective, may not be able to disambiguate cortical layer identity in all cells.

Abstract
Tumour necrosis factor alpha (TNF-alpha) is an innate pro-inflammatory cytokine involved in protection against intracellular pathogens. Existing methods for measuring TNF-alpha production and function in ruminants are limited to ELISA and many rely on polyclonal antisera. With a view to developing improved detection methods for bovine (bov) TNF-alpha, monoclonal antibodies (mAb) were produced by immunising mice with a plasmid encoding bov TNF-alpha. Two of the resulting mAb, termed CC327 and CC328, were used to develop a sandwich ELISA capable of detecting both native and recombinant bov TNF-alpha. This ELISA did not detect recombinant ovine (ov) TNF-alpha. A luminometric method was applied to the ELISA to improve sensitivity for detection of native bov TNF-alpha in culture supernatants derived from bovine monocyte-derived dendritic cells (DC) infected with Mycobacterium bovis. Both CC327 and CC328 detected intracytoplasmic expression of TNF-alpha in mitogen-activated bovine T lymphocytes. However, only CC328 detected intracytoplasmic ovine TNF-alpha in transfected cells, explaining the failure of the sandwich ELISA to detect recombinant ov TNF-alpha. These mAbs have generated the capability to study the role of TNF-alpha in host immune protection and disease pathogenesis in ruminants.

Abstract
Natural killer (NK) cells are critical to the innate defence against intracellular infection. High NK cell frequencies have been detected in human neonates, which may compensate for the relative immaturity of the specific immune response. Additionally, phenotypic subsets of NK cells have been identified in humans with different functional properties. In this study, we examined the age distribution and phenotype of NK populations in bovine peripheral blood, including neonatal animals. We found that the NK cell populations defined by the phenotypes CD3(-)CD2(+) and NKp46(+) largely overlapped, so that the majority of NK cells in bovine peripheral blood were CD3(-)CD2(+)NKp46(+). The remainder of the NK-like cells comprised two minor populations, CD3(-)CD2(+)NKp46(-) and CD3(-)CD2(-)NKp46(+); the relative proportions of these varied with age. The lowest frequency of NK cells was recorded in 1-day-old calves, with the highest frequency in day 0 calves. The phenotypic characteristics of CD3(-)CD2(+) and NKp46(+) NK populations were similar; both populations expressed CD45RO, CD45RB, CD11b, CC84, CD8alphaalpha and CD8alphabeta and did not express CD21, WC1, CD14 or gammadelta TCR. Age-related phenotypic differences were apparent. The phenotypic characteristics of three NK subpopulations were described; a significantly greater proportion of the CD3(-)CD2(-)NKp46(+) population expressed CD8alpha compared to CD3(-)CD2(+)NKp46(+) cells. Furthermore, a significantly greater proportion of the CD3(-)CD2(+)NKp46(-) population expressed CD8 compared to total CD3(-)CD2(+) cells. Adult cattle had a significantly higher proportion of perforin(+) cells compared to calves aged </=6 weeks. In this age group, the majority of perforin(+) cells expressed NKp46, while in adults the majority of perforin(+) cells were NKp46(-). However, the proportion of NKp46(+) and CD3(-)CD2(+) cells that expressed perforin was not significantly different in any age group tested.

Abstract
Two monoclonal antibodies (mAbs), CC17 and IL-A67, which are specific for the bovine equivalent of the CD5 antigen, Bo5, were each found to react with the cells of some animals but not others. The cattle tested were all positive for one or both of the mAbs, but the level of expression on cells expressing both determinants was slightly lower than that on cells expressing either of the determinants on their own. Both mAbs precipitated an antigen of 67 kD. However, sequential immunoprecipitation experiments with cells that reacted with both mAbs demonstrated that the determinants are present on two different sets of molecules. These findings suggested that the mAbs recognize two co-dominantly expressed allelic forms of Bo5. This was confirmed in family studies, with groups of full- and half-sibling offspring of sires and dams of defined phenotypes. These experiments also showed that the gene encoding the Bo5 antigen is not linked to the major histocompatibility complex (MHC). The frequencies of the two alleles, which have been designated Bo5.1 and Bo5.2, in the cattle populations tested were 100% and 0%, respectively, in Bos taurus, and 10% and 90%, respectively, in Bos indicus.

Abstract
A panel of 377 commercially available mAbs were submitted to the animal homologue section of the 8th International Workshop on Human Leukocyte Differentiation Antigens (HLDA8, Adelaide, Australia) for cross-reactivity studies on different animal species. In this study we describe the results of testing the mAbs on cattle cells by flow cytometry and Western blot. Eight commercial suppliers participated, providing mAbs to a total of 144 CD antigens plus controls. Fifty-two mAbs were identified as potentially staining cattle cells in the first round screen. In the second phase, 38 mAbs were confirmed as staining cattle cells. This included some that may recognise polymorphic determinants and others with atypical distribution patterns compared to humans. mAb to human CD9, CD11a, CD14, CD18, CD21, CD23, CD29, CD44, CD45R, CD47, CD49d and CD172a cross-reacted with bovine cells and mAb to CD22, CD88, CD119 and CD163 stained CD antigens that have not previously been identified in cattle.

Abstract
AbstractDendritic cells are central to the initiation of primary immune responses. They are the only antigen-presenting cell capable of stimulating naive T cells, and hence they are pivotal in the generation of adaptive immunity. Dendritic cells also interact with and influence the response of cells of the innate immune system. The manner in which dendritic cells influence the responses in cells of both the innate and adaptive immune systems has consequences for the bias of the adaptive response that mediates immunity to infection after vaccination or infection. It also provides an opportunity to intervene and to influence the response, allowing ways of developing appropriate vaccination strategies. Mouse and human studies have identified myeloid, lymphoid and plasmacytoid dendritic cells. Studies in domesticated animals with agents of specific infectious diseases have confirmed the applicability of certain of the generic models developed from mice or from in vitro studies on human cells. In vivo and ex vivo studies in cattle have demonstrated the existence of a number of subpopulations of myeloid dendritic cells. These cells differ in their ability to stimulate T cells and in the cytokines that they produce, observations clearly having important implications for the bias of the T-cell response. Dendritic cells also interact with the innate immune system, inducing responses that potentially bias the subsequent adaptive response.

Abstract
Gammadelta T-cell receptor(+) T lymphocytes are an important element of the innate immune system. Early production of interferon (IFN)-gamma by gammadelta T cells may have a role in linking innate and adaptive immune responses and contribute to T helper-1 bias. We investigated the role of cytokines in the activation and induction of IFN-gamma secretion by bovine workshop cluster 1(+) (WC1(+)) gammadelta T cells. The effects of culture with interleukin (IL)-12, IL-18, IL-15 and IL-2 were investigated; these cytokines are known to influence murine and human gammadelta T cells. We report that bovine WC1(+)gammadelta T cells are synergistically stimulated by IL-12 and IL-18 to secrete large quantities of IFN-gamma. Neonatal calves were shown to have significantly higher numbers of circulating WC1(+)gammadelta T cells than adult animals. In addition, the response of peripheral blood WC1(+)gammadelta T cells was significantly higher in neonatal calves compared with adult animals. However, in adult animals the response of lymph node WC1(+)gammadelta T cells to IL-12/IL-18 was more pronounced than that of peripheral blood WC1(+)gammadelta T cells. We hypothesize that the induction of IFN-gamma secretion from WC1(+)gammadelta T cells by IL-12 and IL-18 is likely to be an important element of the innate response to pathogens such as Mycobacterium bovis. The high numbers of WC1(+)gammadelta T cells in neonatal calves, and their inherent ability to respond to inflammatory cytokines, could be a key factor in the enhanced responses seen in calves to BCG vaccination.

Abstract
Mycobacterium bovis is the causative agent of bovine tuberculosis, a disease that is increasing in incidence in United Kingdom cattle herds. In addition to increasing economic losses, the rise in bovine tuberculosis poses a human health risk. There is an urgent requirement for effective strategies for disease eradication; this will likely involve vaccination in conjunction with current test and slaughter policies. A policy involving vaccination would require an accurate diagnosis of M. bovis-infected animals and the potential to distinguish these animals from vaccinates. Currently used diagnostic tests, the skin test and gamma interferon (IFN-gamma) blood test, have a sensitivity of up to 95%. A further complication is that M. bovis BCG-vaccinated animals are also scored positive by these tests. We tested the hypothesis that the quantification of IFN-gamma-producing lymphocytes by flow cytometric analysis of intracellular IFN-gamma expression would provide a more accurate discrimination of M. bovis-infected animals from BCG vaccinates. Significant numbers of IFN-gamma-expressing CD4+ T cells were detected following culture of heparinized blood from M. bovis-infected animals, but not from BCG vaccinates, with purified protein derived from M. bovis (PPD-B) or live mycobacteria. Only 1 of 17 BCG-vaccinated animals had a significant number of CD4+ T lymphocytes expressing IFN-gamma, compared with 21/22 M. bovis-infected animals. This assay could allow an accurate diagnosis of M. bovis and allow the discrimination of BCG-vaccinated cattle from infected cattle.

Abstract
Development of reagents against leukocyte differentiation antigens in veterinary immunology is slower compared to humans and mice. Cross-reactivity studies with monoclonal antibodies (mAb) generated against human molecules represent an excellent approach for the detection of new reagents for the minor characterised species. Three hundred seventy-seven commercially available mAb from different companies were tested for their reactivity with cells from 17 species--including non-human primates, ruminants, swine, horse, carnivores, rabbit, guinea pig, chicken and fish. In a first round of testing by flow cytometry (FCM) 182 mAb showed reactivity with atleast one of the species described above. Most of the cross-reactivity was found against non-human primate leukocytes, but also species in evolutionarily more distant from humans showed in some cases a clear staining pattern in flow cytometry (FCM). In a second round these FCM-results were confirmed by molecular analyses, by immunoprecipitation studies and analyses on transfectants. Interesting was the broad species-overlapping reactivity of mAb directed against CD9 (11 out of 17 species), CD11a (11/17), CD14 (11/17), CD18 (13/17), CD21 (7/17), CD29 (10/17), CD44 (13/17), CD45 (9/17), CD47 (10/17), and CD49d (13/17), CD61 (6/17), CD86 (7/17), CD91 (5/17), and CD172a (10/17), indicating evolutionary highly conserved epitopes on these surface molecules. Our results suggest the suitability of crossreactive mAb for the animal model studies. Moreover, these findings contribute to our understanding of the evolution of the immune system.

Abstract
Recombinant bovine IL-4 (rbo IL-4) was transiently expressed in COS-7 cells. Mice were immunised with a plasmid encoding rbo IL-4 and boosted with rbo IL-4. A number of monoclonal antibodies (mAb) were generated that reacted with rbo IL-4 in an ELISA and these cloned hybridomas were termed CC311, CC312, CC313 and CC314. A pair of mAb (CC313 and CC314) was identified that together could be used to detect both recombinant and native bovine IL-4 by ELISA and a luminometric detection method was applied to the ELISA. Using this method native bovine IL-4 was detected in supernatants of PBMC stimulated with mitogens. In addition, high level secretion of IL-4 by Fasciola hepatica specific Th2 clones, but not by a Babesia bovis specific Th1 clone, was confirmed. The ELISA was also able to detect recombinant ovine IL-4. The pair of mAb used for ELISA could also be used for the detection of IL-4 spot forming cells by ELISPOT. In addition intracytoplasmic expression of IL-4 could be detected. The ability to detect ruminant IL-4 by three methods: ELISA, ELISPOT and by flow cytometric analysis of intracytoplasmic expression will permit studies of the role of this important cytokine in the immunology and pathogenesis of animal diseases.

Abstract
Ruminants are a major reservoir of enterohaemorrhagic Escherichia coli (EHEC), which cause acute gastroenteritis in humans with potentially life-threatening sequelae. The mechanisms underlying EHEC persistence in ruminant hosts are poorly understood. EHEC produce several cytotoxins that inhibit the proliferation of bovine lymphocytes in vitro and influence EHEC persistence in calves, suggesting that bacterial suppression of mucosal inflammation may be important in vivo. In order to address this hypothesis, intraepithelial lymphocytes (IEL) obtained from ligated intestinal loops of five 9-14 day old calves were characterized 12 h after inoculation with E. coli strains. Loops were inoculated with an EHEC O103 : H2 strain, an isogenic Deltastx1 mutant incapable of producing Shiga toxin 1 (Stx1) and a porcine non-pathogenic E. coli strain. The IEL mainly comprised activated CD2(+) CD3(+) CD6(+) CD8alpha(+) T cells and resembled IEL obtained from the intestinal mucosa of orally challenged calves. Forty per cent of all IEL were potentially sensitive to Stx1 in that they expressed the receptor for Stx1. Nevertheless, analysis of IEL from inoculated loops failed to detect a significant effect of the different E. coli strains on proliferative capacity, natural killer cell activity or the cytokine mRNA profile. However, the EHEC wild-type strain reduced the percentage of CD8alpha(+) T cells in the ileal mucosa compared with loops inoculated with the Deltastx1 mutant. This shift in IEL composition was not associated with inhibition of IEL proliferation in situ, since the majority of the IEL from all loops were in the G(0)/G(1) phase of the cell cycle. These studies indicate that the ligated ileal loop model will be a useful tool to dissect the mechanisms underlying suppression of mucosal inflammation by EHEC in the reservoir host.

Abstract
Theileria infection of bovine leucocytes induces uncontrolled proliferation and a transformed phenotype comparable to tumour cells. Infected cells have many characteristics of activated leucocytes and use autocrine loops to augment proliferation. We have shown previously that, in infected B cells, PI3-K controls a granulocyte-macrophage colony-stimulating factor (GM-CSF) autocrine loop to increase both proliferation and activation of the activator protein 1 (AP-1) transcription factor. We show here that the same infected B cells also use a tumour necrosis factor (TNF) alpha autocrine loop that again contributes to proliferation and augments nuclear factor (NF)-kappaB activation. Interestingly, both pharmacological inhibition of TNF synthesis and neutralizing anti-TNF antibodies lead to a reduction in proliferation and a 50% drop in NF-kappaB activation, without inducing apoptosis.

Abstract
The objective of the investigation was to provide data on how a prior exposure of cattle to Mycobacterium avium, used here as a model of exposure to an environmental mycobacterium, affected the cellular immune response that follows vaccination with Mycobacterium bovis BCG. The assessment of cellular immune responses included lymphocyte proliferation assays, the delayed hypersensitivity skin test and IFN-gamma synthesis in whole blood cultures. One group of calves was inoculated subcutaneously with M. avium followed 12 weeks later by M. bovis-BCG. The other group was vaccinated subcutaneously with BCG alone. Calves previously exposed to M. avium responded more rapidly, as assessed in the in vitro assays, to purified protein derivative (PPD) from M. avium (PPD-A) or M. bovis (PPD-B) than did calves inoculated with BCG only, indicating that the exposure to M. avium had primed the immune response in these calves. Following inoculation of BCG the intensity of the in vitro responses and the delayed hypersensitivity skin test to PPD-A was higher for the M. avium-primed animals while the responses to PPD-B were similar in the M. avium-primed and BCG-only groups. The results are consistent with a model in which prior exposure to environmental mycobacteria does not necessarily inhibit the immune response to the vaccine strain, BCG. They suggest that M. avium infection primes the immune system of calves and that the detection of an immune response specific for M. bovis BCG is masked by reactivity to antigens also present in M. avium.

Abstract
Recombinant bovine IL-12 (rbo IL-12) was transiently expressed in COS-7 cells and shown to upregulate the synthesis of IFNgamma by bovine cells stimulated with a suboptimal concentration of mitogen in vitro. Mice were immunised with a plasmid encoding rbo IL-12 and boosted with rbo IL-12 and a number of monoclonal antibodies (mAb) were generated that reacted with rbo IL-12 in an ELISA. Some of these mAb neutralised the ability of rbo IL-12 to induce IFNgamma synthesis by bovine cells. A pair of mAb was identified that together could be used to detect both recombinant and natural bovine IL-12 by ELISA and a luminometric detection method was applied to the ELISA making it more sensitive. Using this method native bovine IL-12 was detected in supernatants of dendritic cells (DC) cultured in vitro with a synthetic lipopeptide known to stimulate secretion of IL-12 by human DC. The ELISA was also able to detect recombinant ovine IL-12 and, less effectively, recombinant human IL-12. In contrast, bovine IL-12 was not detected by a commercial human IL-12 ELISA kit. Intracytoplasmic IL-12 was detected in bovine DC using the antibodies described herein. The ability to detect ruminant IL-12 by three methods: ELISA, bioassay with neutralising mAb and cytoplasmic staining, will permit studies of the role of this important cytokine in the immunology and pathogenesis of animal diseases.

Abstract
The objective of the study was to develop an assay for bovine IL-10 that could be applied to analyses of immune responses and advance understanding of a variety of diseases of cattle. Recombinant bovine IL-10 (rbo IL-10) was transiently expressed in Cos-7 cells and shown to inhibit the synthesis of IFN gamma by bovine cells stimulated with antigen in vitro. Mice were immunised with a plasmid containing a cDNA insert encoding rbo IL-10 and inoculated with rbo IL-10. A number of monoclonal antibodies (mAb) were generated that reacted with rbo IL-10 in an ELISA. Some of these mAb neutralised the ability of rbo IL-10 to inhibit IFN gamma synthesis by antigen-stimulated bovine cells. A pair of mAb was identified that together could be used to detect both recombinant and natural bovine IL-10 present in supernatant of PBMC stimulated with ConA. A luminescent detection method was applied to the ELISA making it more sensitive. Using this method native IL-10 was detected in supernatants of PBMC, diluted blood and undiluted blood from cattle immunised with Mycobacterium bovis BCG or ovalbumin and incubated in vitro with antigen indicating the applicability of the assay to a number of in vitro culture systems.

Abstract
Pre-exposure to environmental mycobacteria and induction of an inappropriately biased immune response may be major factors affecting the efficacy of BCG; vaccination of neonates that have not been exposed to environmental mycobacteria may induce more effective immunity. Responses of neonatal calves to mycobacterial antigens using dendritic cells (DC) as antigen-presenting cells were investigated. In nonvaccinated, immunologically naive calves as young as 1 day old, a population of CD8(+) cells proliferated and produced IFN-gamma in response to BCG-infected DC. CD3(-) CD8(+) NK-like and CD3(+) CD8(+) T cells were evident within the responding CD8(+) population. The response was not MHC-restricted. The NK-like CD3(-) cells were the major population producing IFN-gamma. The presence of mycobacteria-reactive, IFN-gamma-secreting CD8(+) NK cells in neonatal calves may have important consequences for the induction of a Th1-biased immune response.

Abstract
The synthesis of IFN gamma and IL-4 by CD4, CD8 and WC1 gamma delta TCR(+) T cell sub-populations, and T cells stained with activation/memory-sub-set markers has been examined by flow cytometric analysis. Cells from blood, prescapular, bronchial and mesenteric lymph nodes and Peyer's patches were incubated with phorbol 12-myristate 13-acetate (PMA), ionomycin and brefeldin-A before staining. Lymphocytes that stained for cytoplasmic IFN gamma were evident within the CD4 and CD8 populations from all tissues and also in the WC1 population from lymph nodes. IL-4 producing cells were primarily evident within the CD4 population. IFN gamma synthesis was evident within both CD45RO(+) and CD45RB(+) populations, but IL-4 synthesis was predominantly by cells that were CD45RO(+)/CD45RB(-). Expression of CD62L is not related to functional memory in CD4(+) T cells from cattle and CD62L(+) cells, particularly from the lymph nodes draining the skin and the lungs, stained with mAb to IFN gamma and IL-4. The findings indicate that at least for CD4(+) T cells, where CD45 isoform expression is related to functional memory, these two cytokines are produced predominantly by cells with a memory phenotype. The observation that some WC1(+) cells produce IFN gamma implies the presence of distinct sub-sets of this gamma delta TCR(+) population cattle and suggests a functional role.

Abstract
The major subset of dendritic cells (DC) from bovine afferent lymph expresses the SIRP alpha MyD-1 antigen, but not CD11a or the antigen recognized by mAb CC81, and potently stimulates CD4+ and CD8+ T lymphocyte proliferation. The minor subpopulation, that is CD11a+ CC81+ MyD-1-, effectively stimulates CD4+ but not CD8+ T lymphocyte proliferation. CD11a+ CC81+ MyD-1- DC did not induce anergy or death or secrete an inhibitory factor. However, supernatant from cultures of CD8+ T cells with CD11a- CC81- MyD-1+ DC significantly enhanced proliferation of CD8+ T cells in response to CD11a+ CC81+ MyD-1- DC, an effect that was blocked by interleukin (IL)-1alpha, but not IL-1beta, specific mAb. The proliferation of CD8+ T cells with CD11a+ CC81+ MyD-1- DC was also enhanced by adding IL-1alpha. IL-1beta slightly enhanced proliferation, whereas IL-2, IL-6, IL-12, and IL-15 had no effect. We conclude that the failure to stimulate CD8+ T cell proliferation results from the lack of IL-1alpha synthesis by this population, which may have important consequences in vivo.

Abstract
Twelve subpanels of monoclonal antibodies (MAb) included within the 6th International Workshop on Human Leukocyte Differentiation Antigens (6th HLDA) were assayed for reactivity with bovine peripheral blood leukocytes. Sixty-nine of the 807 MAb (8.6%) stained bovine cells. These MAb represented 30 different human CD groups. Nine of the MAb to different human CD antigens (CD19, CD23, CD39, CD47, CD86, CD117, CD120b, CDw149, CD165) potentially recognized antigens on cattle cells that had not previously been identified. These were investigated further by two-colour immunofluorescence to compare the cellular expression of the antigen on cattle cells with that reported for the different CD antigens in humans. Four of the MAb that belonged to CD23, CD39, CD47, and CDw149 stained bovine cells in a manner that indicated an almost identical cellular distribution of the antigen to that reported in humans. This implied that these MAb reacted with the homologous cattle molecules. Further work would be necessary to confirm specificity of CD19, CD86, CD117, CD120b and CD165 MAb. Other cross-reacting MAb either recognized antigens already defined in cattle or antigens not yet clustered in humans. The study has identified valuable new reagents for studies of cattle and confirmed that most common cross-reactive MAb are to epitopes on integrins.

Abstract
Few data are available regarding the induction of memory T-lymphocyte responses in cattle following Bacille Calmette Guérin (BCG) vaccination. Studies of the immune response induced by BCG vaccination provide an insight into the basis of antimycobacterial immunity that could be exploited for the development of more effective vaccination strategies. We used autologous dendritic cells (DC) infected with Mycobacterium bovis Bacille Calmette Guérin (BCG) or pulsed with purified protein derivative from M. bovis (PPD-B) or M. avium (PPD-A) to assess responses of CD4+, CD8+ and WC1+ gammadelta TCR+ lymphocytes from BCG vaccinated and nonvaccinated cattle. Mycobacteria-specific CD4+ and CD8+, but not WC1+ gammadelta TCR+, memory T lymphocytes were demonstrated in BCG-vaccinated cattle. CD4+ and CD8+ lymphocytes proliferated and produced interferon (IFN)-gamma in response to BCG-infected or PPD-B-pulsed DC. Proliferative responses were greater for CD4+ than CD8+ lymphocytes, although secretion of IFN-gamma was higher from the CD8+ T cells. Responses to PPD-A-pulsed DC were lower, with no CD8+ response. Lymphocytes from nonvaccinated calves were also stimulated to proliferate by BCG-infected DC, although the magnitude of proliferation was lower. The findings suggest that immunity to M. bovis induced by BCG vaccination in cattle may involve CD8+ memory T cells which produce IFN-gamma, as well as CD4+ memory T cells.

Abstract
Dendritic cells are professional antigen presenting cells derived from the bone marrow and distributed throughout body tissues where they are located in sites that are suitable for antigen uptake. They are central to the induction of immune responses in naive animals and thus have become targets in strategies that are aimed at modulating resistance to infection. Studies in cattle have shown that the dendritic cells are phenotypically heterogeneous and that the different phenotypes have different biological properties. The molecular basis for this variation has begun to be investigated and has led to the identification of a member of the SIRPalpha family of signal regulatory proteins (MyD1) on a subset of dendritic cells in afferent lymph. Uptake of antigen by cattle dendritic cells is by a number of mechanisms that can involve endocytosis via clathrin coated pits or via caveolae as well as macropinocytosis.

Abstract
Changes in lymphocyte subsets in the trachea, pulmonary tissue, bronchoalveolar lavage (BAL), peripheral blood and bronchial lymph node (BLN) of gnotobiotic calves infected with bovine respiratory syncytial virus (BRSV) were analysed by flow cytometry. Following BRSV infection, virus titres in the nasopharynx reached a peak between days 5 and 7 and infection was resolving from day 10. Although calves did not develop signs of clinical respiratory disease, there was evidence of gross pneumonia and histological changes typical of BRSV bronchiolitis, which were most extensive from day 710 of infection. Following BRSV infection there was a recruitment of CD8+ T cells into the trachea and lung, which peaked on day 10 after infection. Thus, there were approximately equal numbers of CD8+ and CD4+ T cells in the lung and trachea of uninfected calves, whereas by day 10 of infection, CD8+ cells outnumbered CD4+ cells by 3:1 in the lungs and 6:1 in the trachea of the infected calves. Although the increase in CD4+ T cells into the lungs was less marked than that of CD8+ T cells, changes in expression of CD45R, CD45RO, L-selectin and interleukin-2 receptors all suggested that CD4+ T cells were activated during BRSV infection. Changes in gamma delta T cells were not observed in BRSV-infected calves. There was a marked increase in B cells in the BLN after infection and BLN CD4+ T cells changed from the majority expressing L-selectin and CD45R in uninfected calves to a predominance of L-selectin- CD45R- CD45RO+ phenotype, 10 days after infection. In conclusion, CD8+ T cells constitute the major lymphocyte subpopulation in the respiratory tract of calves recovering from BRSV infection.

Abstract
Immunofluorescent staining and flow cytometric analysis of dendritic cells from cattle afferent lymph has established that within the afferent lymph veiled cells (ALVC) there are two phenotypically distinct, major populations. One is CD11a+, CD5+, CD21- and expresses the bovine WC10 (workshop cluster 10) molecule and the Ag recognized by mAb CC81 but is not recognized by mAbs CC149 and IL-A24. The second ALVC subpopulation is CD11a-, CD5-, CD21+/-, workshop cluster 10- and is not recognized by mAb CC81 but is recognized by mAb CC149. Thus, the two populations, which can be identified by staining for CD11a, are defined by the differential expression of a number of Ag. The ALVC populations had differing capacities to stimulate T cells. CD11a- ALVC were more effective at stimulating proliferative responses in allogeneic CD4+ T cells and CD8+ T cells. This was not related to binding of CTLA4Ig or CD40L fusion proteins, implying similar levels of expression of their ligands, CD80 and CD86 or CD40. Both subsets were able to present OVA to resting memory CD4+ T cells, indicating that both were able to take up and process soluble native protein. In contrast, the CD11a- ALVC were more effective in presenting respiratory syncytial virus Ag to resting CD4+ T cells. Considering the central role of dendritic cells in the initiation of immune responses in naive animals, the two cell types may have different roles in the induction of primary responses induced following infection or immunization.

Thus, the two populations, which can be identified by staining for CD11a, are defined by the differential expression of a number of Ag. The ALVC populations had differing capacities to stimulate T cells. CD11a- ALVC were more effective at stimulating proliferative responses in allogeneic CD4+ T cells and CD8+ T cells. This was not related to binding of CTLA4Ig or CD40L fusion proteins, implying similar levels of expression of their ligands, CD80 and CD86 or CD40. Both subsets were able to present OVA to resting memory CD4+ T cells, indicating that both were able to take up and process soluble native protein. In contrast, the CD11a- ALVC were more effective in presenting respiratory syncytial virus Ag to resting CD4+ T cells. Considering the central role of dendritic cells in the initiation of immune responses in naive animals, the two cell types may have different roles in the induction of primary responses induced following infection or immunization.

Abstract
Thirty-seven subpanels of monoclonal antibodies (mAbs) included within the Vth International Workshop on Human Leucocyte Differentiation Antigens (Vth Workshop) were assayed for reactivity with bovine peripheral blood leucocytes. Sixty-five of the 772 mAbs (8.4%) stained bovine cells. mAbs from each of the 27 different CD groups that contained a mAb reacting with cattle were further investigated to compare the cellular expression of the antigen in cattle with that reported for the different CD antigens in humans. Two-colour immunofluorescence staining of the Vth Workshop mAbs against characterized bovine leucocyte subpopulation markers that identified monocytes, B cells, CD4, CD8 and WC1 +T cells were used for these analyses. Eighteen of the mAbs to different human CD antigens (CD11a, CD14, CD18, CD21, CD27, CD29, CD49a, CD49b, CD49d, CD49e, CD51, CD61, CD62L, CD62P, CD63, CDw78, CD98, CD100) stained bovine antigens with an almost identical cellular distribution to that reported in humans. This implies that these mAb react with the homologous cattle molecules. Nine mAbs (CD35, CD37, CD49c, CD50, CD54, CD66, CD81, CD88, CD102) stained bovine cells but the cellular distribution of the bovine antigen was different to that reported in humans implying either a different cellular distribution for these antigens in cattle or a reaction with a different molecule. The investigation has allowed the identification of several bovine homologues of human CD antigens that have not been previously defined in cattle and the cross-reacting mAbs will be valuable reagents for future investigations of bovine immunology.

Abstract
An in vitro model system has been developed in which freshly isolated resting WC1+ gamma/delta TcR+ T cells proliferate in response to cells transformed by the protozoan parasite Theileria annulata, providing a strategy in which the basis of activation of naive gamma/delta T cells can be investigated. Irradiated parasite-transformed cells stimulate the proliferation, but not cytolytic activity, of autologous peripheral blood mononuclear cells (PBMC) from non-immune animals. The proliferating cells are mainly WC1+ gamma/delta T cells. The majority of WC1+ gamma/delta T cells in freshly isolated PBMC express CD25 at a low level that increases when stimulated with T. annulata-infected cells. Purified WC1+ gamma/delta T cells fail to proliferate when cultured with irradiated T. annulata-infected cells and produce a small proliferative response to IL-2, but proliferate strongly to irradiated or lightly fixed Theileria-infected cells in combination with IL-2. The Theileria-infected cells express cytokine transcripts encoding IL-1 alpha, IL-1 beta, IL-6 and IL-10, but not IFN gamma, IL-2, IL-4 and IL-7. Purified WC1+ gamma/delta T cells stimulated with T. annulata-infected cells with or without IL-2 fail to produce IL-2 transcripts, but do produce those for TNF alpha. These experiments show that WC1+ gamma/delta T cells recognize a surface determinant on T. annulata-infected cells, that together with a second signal, which can be provided by exogenous IL-2, stimulates their proliferation.

Abstract
Dendritic cells were identified in afferent lymph derived by lymphatic cannulation of cattle, stained with monoclonal antibody (mAb) to the bovine workshop cluster 6 (WC6) antigen, which is highly expressed on bovine afferent lymph veiled cells, and sorted with a fluorescence-activated cell sorter. These cells expressed major histocompatibility complex (MHC) class I and II and CD1b but not CD14. They bound human and murine CTLA4-immunoglobulin (CTLA4-Ig) fusion proteins indicating expression of CD80 and or CD86. Dendritic cells induced proliferative responses in allogeneic CD4+ and CD8+ cells sorted from blood but did not induce responses in purified allogeneic WC1+, gamma/delta T cells, which are CD2-, CD4-, CD8- and are the major gamma delta T-cell population in cattle blood, even when interleukin-2 (IL-2) was added to cultures. A WC1-, CD2+ gamma delta T-cell receptor (TCR)+ population predominates in cattle spleens and proliferation of a T-cell line with this phenotype was not induced by allogeneic dendritic cells, with or without added IL-2. The observations imply that the ligand for the gamma delta TCR expressed on the two populations is not present on allogeneic dendritic cells or that the costimulatory molecules expressed on dendritic cells that render them highly effective at stimulating MHC class I- and class II-restricted CD8+ and CD4+ T cells are not recognized by the WC1+ or WC1- gamma/delta T cells. Expression of CD28 by the four cell types was assessed by reverse transcriptase-polymerase chain reaction (RT-PCR). Purified CD4+ and CD8+ cells both produced CD28 transcripts but neither purified WC1+ cells nor the WC1- gamma delta TCR+ cell line did so. The findings indicate that CD80 and or CD86 are involved in the stimulation of CD4+ and CD8+ alpha beta TCR+ T cells but not in the stimulation of either of the two gamma delta TCR+ populations.

Abstract
Eight monoclonal antibodies (mAbs) clustered together in a statistical analysis of data submitted to the Third Workshop on Ruminant Leucocyte Antigens to form provisional cluster (PC) 36. PC36 included the CD45R workshop control mAb CC76. The mAbs were compared by two-colour immunofluorescence with mAbs against other leucocyte subpopulation antigens. The flow cytometry results indicated that all of the mAbs identified CD45R.

Abstract
Six monoclonal antibodies (mAbs) that clustered together in a statistical analysis of data submitted to the Third Workshop on Ruminant Leucocyte Antigens and mAb CC-G33 were tested for ability to stain COS-7 cells transfected with cDNA encoding human CD14. Only mAb CC-G33 recognised the human molecule. The six mAbs were compared with mAb CC-G33 by flow cytometry and three were shown to be directed against bovine CD14.

Abstract
An antigen has been identified, recognized by a novel monoclonal antibody CC45, which is expressed by a subpopulation of bovine gamma/delta T-cell receptor-positive (gamma/delta TCR+) T cells restricted in their distribution to the intestinal epithelium. This subset of intestinal intraepithelial lymphocytes (iIEL) which represented 8-29% of gamma/delta TCR+ T cells in the gut epithelium expressed CD45, CD3 and L-selectin; most of these cells were CD2- and CD8-. Electron microscopic studies of CC45+ cells revealed that they were large mononuclear leucocytes containing numerous mitochondria and smooth vesicles; a proportion of these contained membrane-bound dense granules. Immunoprecipitation of 125I-labelled iIEL analysed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis under reducing and non-reducing conditions revealed polypeptides of 60,000 and 200,000 molecular weights, respectively indicating that the antigen, which appears distinct from molecules described in other species, is expressed on the cell surface as a complex.
