Abstract
Introduction Increasing evidence has shown that coronavirus disease 19 (COVID-19) severity is driven by a dysregulated immunological response. Previous studies have demonstrated that natural killer (NK) cell dysfunction underpins severe illness in COVID-19 patients, but have lacked an in-depth analysis of NK cell markers as a driver of death in the most critically ill patients. Methods We enrolled 50 non-vaccinated hospitalized patients infected with the initial virus or the alpha variant of SARS-CoV-2 with moderate or severe illness, to evaluate phenotypic and functional features of NK cells. Results Here, we show that, consistent with previous studies, evolution NK cells from COVID-19 patients are more activated, with the decreased activation of natural cytotoxicity receptors and impaired cytotoxicity and IFN-γ production, in association with disease regardless of the SARS-CoV-2 strain. Fatality was observed in 6 of 17 patients with severe disease; NK cells from all of these patients displayed a peculiar phenotype of an activated memory-like phenotype associated with massive TNF-α production. Discussion These data suggest that fatal COVID-19 infection is driven by an uncoordinated inflammatory response in part mediated by a specific subset of activated NK cells.

Abstract
For intradermal (ID) immunisation, novel needle-based delivery systems have been proposed as a better alternative to the Mantoux method. However, the penetration depth of needles in the human skin and its effect on immune cells residing in the different layers of the skin has not been analyzed. A novel and user-friendly silicon microinjection needle (Bella-muTM) has been developed, which allows for a perpendicular injection due to its short needle length (1.4-1.8 mm) and ultrashort bevel. We aimed to characterize the performance of this microinjection needle in the context of the delivery of a particle-based outer membrane vesicle (OMV) vaccine using an ex vivo human skin explant model. We compared the needles of 1.4 and 1.8 mm with the conventional Mantoux method to investigate the depth of vaccine injection and the capacity of the skin antigen-presenting cell (APC) to phagocytose the OMVs. The 1.4 mm needle deposited the antigen closer to the epidermis than the 1.8 mm needle or the Mantoux method. Consequently, activation of epidermal Langerhans cells was significantly higher as determined by dendrite shortening. We found that five different subsets of dermal APCs are able to phagocytose the OMV vaccine, irrespective of the device or injection method. ID delivery using the 1.4 mm needle of a OMV-based vaccine allowed epidermal and dermal APC targeting, with superior activation of Langerhans cells. This study indicates that the use of a microinjection needle improves the delivery of vaccines in the human skin.

Abstract
INTRODUCTION Several studies have shown that intradermal vaccination leads to improved immune responses. In addition, lowering vaccine doses will reduce costs and therefore potentially increase coverage. To determine whether intradermal delivery enhances the antibody responses against the 13-valent pneumococcal conjugate vaccine (PCV13), we compared intradermally and intramuscularly vaccinated mice. METHODS Mice were immunized with PCV13, either intradermally or intramuscularly and CFU-counts in the nasal tissue were determined three or seven days after intranasal colonization with a serotype 4 clinical strain. Antibody concentrations against all thirteen polysaccharides were measured in blood and mucosal samples using a fluorescent-bead-based multiplex immunoassay. RESULTS Antibody levels in both serum and mucosal samples were higher in the intramuscularly vaccinated group as compared to the intradermally vaccinated group. No protection against S. pneumoniae intranasal colonization was observed for either vaccination route. CONCLUSIONS Intradermal vaccination was inferior to intramuscular immunization in inducing serotype-specific antibodies.

Abstract
W614A-3S peptide is a modified 3S motif of the HIV-gp41 (mutation W614A). We previously detected the presence of natural neutralizing antibodies directed against W614A-3S peptide (NAbs) in long-term non-progressor HIV+ patients. Here, we compared the efficacy of W614A-3S peptide formulated in either squalene emulsion (SQE) or in aluminum hydroxide (Alum) in inducing broadly-NAbs (bNAbs). Rabbit and mouse models were used to screen the induction of bNAbs following 4 immunizations. SQE was more efficient than Alum formulation in inducing W614A-3S-specific bNAbs with up to 67%-93% of HIV strains neutralized. We then analyzed the quality of peptide-specific murine B cells by single-cell gene expression by quantitative reverse transcription-PCR and single-cell V(D)J sequencing. We found more frequent germinal center B cells in SQE than in Alum, albeit with a different gene expression profile. The V(D)J sequencing of W614A-3S-specific BCR showed significant differences in BCR sequences and validates the dichotomy between adjuvant formulations. All sixteen BCR sequences which were cloned were specific of peptide. Adjuvant formulations of W614A-3S-peptide-conjugated immunogen impact the quantity and quality of B cell immune responses at both the gene expression level and BCR sequence.

Abstract
The immunopathological pulmonary mechanisms leading to Coronavirus Disease (COVID-19)-related death in adults remain poorly understood. Bronchoalveolar lavage (BAL) and peripheral blood sampling were performed in 74 steroid and non-steroid-treated intensive care unit (ICU) patients (23-75 years; 44 survivors). Peripheral effector SARS-CoV-2-specific T cells were detected in 34/58 cases, mainly directed against the S1 portion of the spike protein. The BAL lymphocytosis consisted of T cells, while the mean CD4/CD8 ratio was 1.80 in non-steroid- treated patients and 1.14 in steroid-treated patients. Moreover, strong BAL SARS-CoV-2 specific T-cell responses were detected in 4/4 surviving and 3/3 non-surviving patients. Serum IFN-γ and IL-6 levels were decreased in steroid-treated patients when compared to non-steroid treated patients. In the lung samples from 3 (1 non-ICU and 2 ICU) additional deceased cases, a lymphocytic memory CD4 T-cell angiopathy colocalizing with SARS-CoV-2 was also observed. Taken together, these data show that disease severity occurs despite strong antiviral CD4 T cell-specific responses migrating to the lung, which could suggest a pathogenic role for perivascular memory CD4 T cells upon fatal COVID-19 pneumonia.

Abstract
Background Lymphopenia and the neutrophil/lymphocyte ratio may have prognostic value in COVID-19 severity. Objective We investigated neutrophil subsets and functions in blood and bronchoalveolar lavage (BAL) of COVID-19 patients on the basis of patients’ clinical characteristics. Methods We used a multiparametric cytometry profiling based to mature and immature neutrophil markers in 146 critical or severe COVID-19 patients. Results The Discovery study (38 patients, first pandemic wave) showed that 80% of Intensive Care Unit (ICU) patients develop strong myelemia with CD10−CD64+ immature neutrophils (ImNs). Cellular profiling revealed three distinct neutrophil subsets expressing either the lectin‐like oxidized low‐density lipoprotein receptor‐1 (LOX‐1), the interleukin-3 receptor alpha (CD123), or programmed death-ligand 1 (PD-L1) overrepresented in ICU patients compared to non-ICU patients. The proportion of LOX-1- or CD123-expressing ImNs is positively correlated with clinical severity, cytokine storm (IL-1β, IL-6, IL-8, TNFα), acute respiratory distress syndrome (ARDS), and thrombosis. BALs of patients with ARDS were highly enriched in LOX-1-expressing ImN subsets and in antimicrobial neutrophil factors. A validation study (118 patients, second pandemic wave) confirmed and strengthened the association of the proportion of ImN subsets with disease severity, invasive ventilation, and death. Only high proportions of LOX-1-expressing ImNs remained strongly associated with a high risk of severe thrombosis independently of the plasma antimicrobial neutrophil factors, suggesting an independent association of ImN markers with their functions. Conclusion LOX-1-expressing ImNs may help identifying COVID-19 patients at high risk of severity and thrombosis complications.

Abstract
The importance of the adaptive T cell response in the control and resolution of viral infection has been well established. However, the nature of T cell–mediated viral control mechanisms in life-threatening stages of COVID-19 has yet to be determined. The aim of the present study was to determine the function and phenotype of T cell populations associated with survival or death of patients with COVID-19 in intensive care as a result of phenotypic and functional profiling by mass cytometry. Increased frequencies of circulating, polyfunctional CD4+CXCR5+HLA-DR+ stem cell memory T cells (Tscms) and decreased proportions of granzyme B–expressing and perforin-expressing effector memory T cells were detected in recovered and deceased patients, respectively. The higher abundance of polyfunctional PD-L1+CXCR3+CD8+ effector T cells (Teffs), CXCR5+HLA-DR+ Tscms, and anti-nucleocapsid (anti-NC) cytokine-producing T cells permitted us to differentiate between recovered and deceased patients. The results from a principal component analysis show an imbalance in the T cell compartment that allowed for the separation of recovered and deceased patients. The paucity of circulating PD-L1+CXCR3+CD8+ Teffs and NC-specific CD8+ T cells accurately forecasts fatal disease outcome. This study provides insight into the nature of the T cell populations involved in the control of COVID-19 and therefore might impact T cell–based vaccine designs for this infectious disease.

Abstract
Immunomonitoring is the study of an individual's immune responses over the course of vaccination or infection. In the infectious context, exploring the innate and adaptive immune responses will help to investigate their contribution to viral control or toxicity. After vaccination, immunomonitoring of the correlate(s) and surrogate(s) of protection is a major asset for measuring vaccine immune efficacy. Conventional immunomonitoring methods include antibody-based technologies that are easy to use. However, promising sensitive high-throughput technologies allowed the emergence of holistic approaches. This raises the question of data integration methods and tools. These approaches allow us to increase our knowledge on immune mechanisms as well as the identification of key effectors of the immune response. However, the depiction of relevant findings requires a well-rounded consideration beforehand about the hypotheses, conception, organization and objectives of the immunomonitoring. Therefore, well-standardized and comprehensive studies fuel insight to design more efficient, rationale-based vaccines and therapeutics to fight against infectious diseases. Hence, we will illustrate this review with examples of the immunomonitoring approaches used during vaccination and the COVID-19 pandemic.

Abstract
Background Our previous work has demonstrated the benefits of transcutaneous immunization in targeting Langerhans cells and preferentially inducing CD8 T-cell responses. Methods In this randomized phase Ib clinical trial including 20 HIV uninfected volunteers, we compared the safety and immunogenicity of the MVA recombinant vaccine expressing HIV-B antigen (MVA-B) by transcutaneous and intramuscular routes. We hypothesized that the quality of innate and adaptive immunity differs according to the route of immunization and explored the quality of the vector vaccine-induced immune responses. We also investigated the early blood transcriptome and serum cytokine levels to identify innate events correlated with the strength and quality of adaptive immunity. Results We demonstrate that MVA-B vaccine is safe by both routes, but that the quality and intensity of both innate and adaptive immunity differ significantly. Transcutaneous vaccination promoted CD8 responses in the absence of antibodies and slightly affected gene expression, involving mainly genes associated with metabolic pathways. Intramuscular vaccination, on the other hand, drove robust changes in the expression of genes involved in IL-6 and interferon signalling pathways, mainly those associated with humoral responses, and also some levels of CD8 response. Conclusion Thus, vaccine delivery route perturbs early innate responses that shape the quality of adaptive immunity. Clinical Trial Registration http://ClinicalTrials.gov, identifier PER-073-13.

Abstract
The skin plays a crucial role in host defences against microbial attack and the innate cells must provide the immune system with sufficient information to organize these defences. This unique feature makes the skin a promising site for vaccine administration. Although cellular innate immune events during vaccination have been widely studied, initial events remain poorly understood. Our aim is to determine molecular biomarkers of skin innate reaction after intradermal (i.d.) immunization. Using an ex vivo human explant model from healthy donors, we investigated by NanoLC-MS/MS analysis and MALDI-MSI imaging, to detect innate molecular events (lipids, metabolites, proteins) few hours after i.d. administration of seasonal trivalent influenza vaccine (TIV). This multimodel approach allowed to identify early molecules differentially expressed in dermal and epidermal layers at 4 and 18 h after TIV immunization compared with control PBS. In the dermis, the most relevant network of proteins upregulated were related to cell-to-cell signalling and cell trafficking. The molecular signatures detected were associated with chemokines such as CXCL8, a chemoattractant of neutrophils. In the epidermis, the most relevant networks were associated with activation of antigen-presenting cells and related to CXCL10. Our study proposes a novel step-forward approach to identify biomarkers of skin innate reaction. SIGNIFICANCE: To our knowledge, there is no study analyzing innate molecular reaction to vaccines at the site of skin immunization. What is known on skin reaction is based on macroscopic (erythema, redness…), microscopic (epidermal and dermal tissues) and cellular events (inflammatory cell infiltrate). Therefore, we propose a multimodal approach to analyze molecular events at the site of vaccine injection on skin tissue. We identified early molecular networks involved biological functions such cell migration, cell-to-cell interaction and antigen presentation, validated by chemokine expression, in the epidermis and dermis, then could be used as early indicator of success in immunization.

Abstract
Epidemiological data suggest that influenza vaccination protects against all‐cause mortality in chronic obstructive pulmonary disease (COPD) patients. However, recent work has suggested there is a defect in the ability of some COPD patients to mount an adequate humoral response to influenza vaccination. The aim of our study was to investigate humoral and cell‐mediated vaccine responses to the seasonal trivalent influenza vaccination (TIV) in COPD subjects and healthy controls. Forty‐seven subjects were enrolled into the study; 23 COPD patients, 13 age‐matched healthy controls (HC ≥ 50) and 11 young healthy control subjects (YC ≤ 40). Serum and peripheral blood mononuclear cells (PBMC) were isolated pre‐TIV vaccination and at days 7 and 28 and 6 months post‐vaccine for haemagglutinin inhibition (HAI) titre, antigen‐specific T cell and antibody‐secreting cell analysis. The kinetics of the vaccine response were similar between YC, HC and COPD patients and there was no significant difference in antibody titres between these groups at 28 days post‐vaccine. As we observed no disease‐dependent differences in either humoral or cellular responses, we investigated if there was any association of these measures with age. H1N1 (r = −0·4253, P = 0·0036) and influenza B (r = −0·344, P = 0·0192) antibody titre at 28 days negatively correlated with age, as did H1N1‐specific CD4+ T helper cells (r = −0·4276, P = 0·0034). These results suggest that age is the primary determinant of response to trivalent vaccine and that COPD is not a driver of deficient responses per se. These data support the continued use of the yearly trivalent vaccine as an adjunct to COPD disease management.

Abstract
BACKGROUND Systems vaccinology allows cutting-edge analysis of innate biomarkers of vaccine efficacy. We have been exploring novel strategies to shape the adaptive immune response, by targeting innate immune cells through novel immunization routes. METHODS This randomized phase I/II clinical study (n=60 healthy subjects aged 18-45 years old) used transcriptomic analysis to discover early biomarkers of immune response quality after transcutaneous (t.c.), intradermal (i.d.), and intramuscular (i.m.) administration of a trivalent influenza vaccine (TIV season 2012-2013) (1:1:1 ratio). Safety and immunogenicity (hemagglutinin inhibition (HI), microneutralization (MN) antibodies and CD4, CD8 effector T cells) were measured at baseline Day (D)0 and at D21. Blood transcriptome was analyzed at D0 and D1. RESULTS TIV-specific CD8+GranzymeB+(GRZ) T cells appeared in more individuals immunized by the t.c. and i.d. routes, while immunization by the i.d. and i.m. routes prompted high levels of HI antibody titers and MN against A/H1N1 and A/H3N2 influenza viral strains. The early innate gene signature anticipated immunological outcome by discriminating two clusters of individuals with either distinct humoral or CD8 cytotoxic responses. Several pathways explained this dichotomy confirmed by nine genes and serum level of CXCL10 were correlated with either TIV-specific cytotoxic CD8+GRZ+ T-cell or antibody responses. A logistic regression analysis demonstrated that these nine genes and serum levels of CXCL10 (D1/D0) best foreseen TIV-specific CD8+GRZ+ T-cell and antibody responses at D21. CONCLUSION This study provides new insight into the impact of immunization routes and innate signature in the quality of adaptive immune responses.

Abstract
BACKGROUND Cross-talk between skin keratinocytes (KCs) and Langerhans cells (LCs) plays a fundamental role in the body's first line of immunological defences. However, the mechanism behind the interaction between these two major epidermal cells is unknown. Interleukin (IL)-32 is produced in inflammatory skin disorders. We questioned the role of IL-32 in the epidermis. OBJECTIVES We aimed to determine the role of IL-32 produced by KCs on surrounding LCs. METHODS We used an ex vivo human explant model from healthy donors and investigated the role of IL-32 on LC activation using imaging, flow cytometry, reverse transcriptase quantitative polymerase chain reaction and small interfering (si)RNA treatment. RESULTS Modified vaccinia virus ankara (MVA) infection induced KC death alongside the early production of the proinflammatory cytokine IL-32. We demonstrated that IL-32 produced by MVA-infected KCs induced modest but significant morphological changes in LCs and downregulation of adhesion molecules, such as epithelial cell adhesion molecule and very late antigen-4, and CXCL10 production. The treatment of KCs with IL-32-specific siRNA, and anti-IL-32 blocking antibody significantly inhibited LC activation, demonstrating the role of IL-32 in LC activation. We also found that some Toll-like receptor ligands induced a very high level of IL-32 production by KCs, which initiated LC activation. CONCLUSIONS We propose, for the first time, that IL-32 is a molecular link between KCs and LCs in healthy skin, provoking LC migration from the epidermis to the dermis prior to their migration to the draining lymph nodes.

Abstract
The magnitude, quality, and maintenance of immunological memory after infection or vaccination must be considered for future design of effective influenza vaccines. In 2009, the influenza pandemic produced disease that ranged from mild to severe, even fatal, illness in infected healthy adults and led to vaccination of a portion of the population with the adjuvanted, inactivated influenza A(H1N1)pdm09 vaccine. Here, we have proposed a multiparameter quantitative and qualitative approach to comparing adaptive immune memory to influenza 1 year after mild or severe infection or vaccination. One year after antigen encounter, severely ill subjects maintained high levels of humoral and polyfunctional effector/memory CD4⁺ T cells responses, while mildly ill and vaccinated subjects retained strong cellular immunity, as indicated by high levels of mucosal homing and degranulation markers on IFN-γ⁺ antigen-specific T cells. A principal component analysis distinguished 3 distinct clusters of individuals. The first group comprised vaccinated and mildly ill subjects, while clusters 2 and 3 included mainly infected individuals. Each cluster had immune memory profiles that differed in magnitude and quality. These data provide evidence that there are substantial similarities between the antiinfluenza response that mildly ill and vaccinated individuals develop and that this immune memory signature is different from that seen in severely ill individuals.

Abstract
Most vaccines, including those against influenza, were developed by focusing solely on humoral response for protection. However, vaccination activates different adaptive compartments that might play a role in protection. We took advantage of the pandemic 2009 A(H1N1) influenza vaccination to conduct a longitudinal integrative multiparametric analysis of seven immune parameters in vaccinated subjects. A global analysis underlined the predominance of induction of humoral and CD4 T cell responses, whereas pandemic 2009 A(H1N1)-specific CD8 responses did not improve after vaccination. A principal component analysis and hierarchical clustering of individuals showed a differential upregulation of influenza vaccine-specific immunity including hemagglutination inhibition titers, IgA(+) and IgG(+) Ab-secreting cells, effector CD4 or CD8 T cell frequencies at day 21 among individuals, suggesting a fine-tuning of the immune parameters after vaccination. This is related to individual factors including the magnitude and quality of influenza-specific immune responses before vaccination. We propose a graphical delineation of immune determinants that would be essential for a better understanding of vaccine-induced immunity in vaccination strategies.

Abstract
While the immunological correlates of hepatitis C virus (HCV)-specific immunity are not well understood, it is now admitted that an effective vaccine against HCV will need to induce both cellular and humoral immune responses and address viral heterogeneity to prevent immune escape. We developed a vaccine platform specifically aimed at inducing such responses against HCV antigens displayed by recombinant retrovirus-based virus-like particles (VLPs) made of Gag of murine leukemia virus. Both ex vivo produced VLPs and plasmid DNA encoding VLPs can be used as vaccines. Here, we report that immunizations with plasmid DNA forming VLPs pseudotyped with HCV E1 and E2 envelope glycoproteins (HCV-specific plasmo-retroVLPs) induce strong T-cell-mediated immune responses that can be optimized by using proper DNA delivery methods and/or genetic adjuvants. Additionally, multigenotype or multi-specific T-cell responses were observed after immunization with plasmids that encode VLPs pseudotyped with E1E2 derived from numerous viral genotypes and/or displaying NS3 antigen in capsid proteins. While homologous prime-boost immunizations with HCV-specific plasmo-retroVLPs or ex vivo produced VLPs induce a low level of specific antibody responses, optimal combination of plasmo-retroVLPs and VLPs was identified for inducing HCV-specific T-cell and B-cell responses as well as neutralizing antibodies. Altogether, these results have important meanings for the development of anti-HCV preventive vaccines and exemplify the flexibility and potential of our retrovirus-based platform in inducing broad cellular and humoral immune responses.

Abstract
BACKGROUND Current conventional vaccination approaches do not induce potent CD8 T-cell responses for fighting mostly variable viral diseases such as influenza, avian influenza viruses or HIV. Following our recent study on vaccine penetration by targeting of vaccine to human hair follicular ducts surrounded by Langerhans cells, we tested in the first randomized Phase-Ia trial based on hair follicle penetration (namely transcutaneous route) the induction of virus-specific CD8 T cell responses. METHODS AND FINDINGS We chose the inactivated influenza vaccine - a conventional licensed tetanus/influenza (TETAGRIP) vaccine - to compare the safety and immunogenicity of transcutaneous (TC) versus IM immunization in two randomized controlled, multi-center Phase I trials including 24 healthy-volunteers and 12 HIV-infected patients. Vaccination was performed by application of inactivated influenza vaccine according to a standard protocol allowing the opening of the hair duct for the TC route or needle-injection for the IM route. We demonstrated that the safety of the two routes was similar. We showed the superiority of TC application, but not the IM route, to induce a significant increase in influenza-specific CD8 cytokine-producing cells in healthy-volunteers and in HIV-infected patients. However, these routes did not differ significantly for the induction of influenza-specific CD4 responses, and neutralizing antibodies were induced only by the IM route. The CD8 cell response is thus the major immune response observed after TC vaccination. CONCLUSIONS This Phase Ia clinical trial (Manon05) testing an anti-influenza vaccine demonstrated that vaccines designed for antibody induction by the IM route, generate vaccine-specific CD8 T cells when administered transcutaneously. These results underline the necessity of adapting vaccination strategies to control complex infectious diseases when CD8 cellular responses are crucial. Our work opens up a key area for the development of preventive and therapeutic vaccines for diseases in which CD8 cells play a crucial role. TRIAL REGISTRATION Clinicaltrials.gov NCT00261001.

Abstract
Vaccinia virus (VV) vaccination is used to immunize against smallpox and historically was considered to have been successful if a skin lesion formed at the vaccination site. While antibody responses have been widely proposed as a correlate of efficacy and protection in humans, the role of cellular and humoral immunity in VV-associated skin lesion formation was unknown. We therefore investigated whether long-term residual humoral and cellular immune memory to VV, persisting 30 years after vaccination, could control VV-induced skin lesion in revaccinated individuals. Here, we have shown that residual VV-specific IFN-gamma+TNF-alpha+ or IFN-gamma+IL-2+ CD4+ lymphocytes but not CD8+ effector/memory lymphocytes expressing a skin-homing marker are inversely associated with the size of the skin lesion formed in response to revaccination. Indeed, high numbers of residual effector T cells were associated with lower VV skin lesion size after revaccination. In contrast, long-term residual VV-specific neutralizing antibody (NAbs) titers did not affect skin lesion formation. However, the size of the skin lesion strongly correlated with high levels of NAbs boosted after revaccination. These findings demonstrate a potential role for VV-specific CD4+ responses at the site of VV-associated skin lesion, thereby providing new insight into immune responses at these sites and potentially contributing to the development of new approaches to measure the efficacy of VV vaccination.

Abstract
Background Obtaining a certain multi-functionality of cellular immunity for the control of infectious diseases is a burning question in immunology and in vaccine design. Early events, including antigen shuttling to secondary lymphoid organs and recruitment of innate immune cells for adaptive immune response, determine host responsiveness to antigens. However, the sequence of these events and their impact on the quality of the immune response remain to be elucidated. Here, we chose to study Modified Vaccinia virus Ankara (MVA) which is now replacing live Smallpox vaccines and is proposed as an attenuated vector for vaccination strategies against infectious diseases. Methodology/Principal findings We analyzed in vivo mechanisms triggered following intradermal (i.d.) and intramuscular (i.m.) Modified Vaccinia virus Ankara (MVA) administration. We demonstrated significant differences in the antigen shuttling to lymphoid organs by macrophages (MΦs), myeloid dendritic cells (DCs), and neutrophils (PMNs). MVA i.d. administration resulted in better antigen distribution and more sustained antigen-presenting cells (APCs) recruitment into draining lymph nodes than with i.m. administration. These APCs, which comprise both DCs and MΦs, were differentially involved in T cell priming and shaped remarkably the quality of cytokine-producing virus-specific T cells according to the entry route of MVA. Conclusions/Significance This study improves our understanding of the mechanisms of antigen delivery and their consequences on the quality of immune responses and provides new insights for vaccine development.

Abstract
Parkinson disease (PD) is a neurodegenerative disorder characterized by a loss of dopamine-containing neurons. Mounting evidence suggests that dopaminergic cell death is influenced by the innate immune system. However, the pathogenic role of the adaptive immune system in PD remains enigmatic. Here we showed that CD8+ and CD4+ T cells but not B cells had invaded the brain in both postmortem human PD specimens and in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of PD during the course of neuronal degeneration. We further demonstrated that MPTP-induced dopaminergic cell death was markedly attenuated in the absence of mature T lymphocytes in 2 different immunodeficient mouse strains (Rag1-/- and Tcrb-/- mice). Importantly, similar attenuation of MPTP-induced dopaminergic cell death was seen in mice lacking CD4 as well as in Rag1-/- mice reconstituted with FasL-deficient splenocytes. However, mice lacking CD8 and Rag1-/- mice reconstituted with IFN-gamma-deficient splenocytes were not protected. These data indicate that T cell-mediated dopaminergic toxicity is almost exclusively arbitrated by CD4+ T cells and requires the expression of FasL but not IFNgamma. Further, our data may provide a rationale for targeting the adaptive arm of the immune system as a therapeutic strategy in PD.

Abstract
Induction of T cell responses has become one of the major goals in therapeutic vaccination against viral diseases and cancer. The use of the skin as target organ for vaccine has been spurred by recent implication of epithelial dendritic cells in CD8 cell cross-priming and suggests that vaccination via the transcutaneous (TC) route may be relevant in the induction of cellular immune responses. We have previously shown that TC application of nanoparticles, on human skin explants, allows targeting of epidermal dendritic cells, possibly via hair follicles. In this study, we have investigated cellular immune responses against an influenza protein-based vaccine by TC vaccination, compared with i.m. vaccination in humans. In this study on 11 healthy volunteers, we found that a newly developed protocol based on cyanoacrylate skin surface stripping induced a significant increase in IFN-gamma-producing T cells specific for influenza vaccine by ELISPOT assays. Interestingly, TC vaccination induced both effector CD4 and CD8 T cell responses, whereas i.m. injection induced strong effector CD4 in the absence of CD8 T cells, as assessed by intracellular cytokine staining and tetramer analyses. This study proposes new perspectives for the development of vaccination strategies that trigger T cell immune responses in humans.

Abstract
Upon antigenic stimulation, establishment of adaptive immune responses that determines vaccine efficacy is dependent on efficient T cell priming. Here, single CX3CL1-Ig DNA administration, a unique ligand of CX3CR1, together with viral or tumor antigens induced a strong in vivo antigen-specific T cell proliferation and effector function that was enough efficient to protect against a tumor challenge. We also showed that early expression of CX3CL1-Ig and antigens in muscle and lymphoid organs induces an increased in vivo migration of myeloid CD14+CD11c+ DC but not lymphoid CD8alpha+CD11c+ DC at these sites. Thus, by effectively directing DC toward lymphoid organs to encounter T cells, CX3CL1-Ig become a new candidate that augments T cell priming and increases efficiency of vaccination.

Abstract
CCR6, a homeostatic chemokine receptor, is shown here to characterize subsets of both central and effector memory T cells that secrete high levels of IL-2 and TNF-alpha in response to polyclonal and antigen-specific stimulation. CCR6(+) T lymphocytes disappeared dramatically from the peripheral blood of HIV-infected patients as HIV disease progressed. The capacity of CD4(+)CCR6(+) to secrete multiple cytokines remained intact among HIV-infected long-term nonprogressors but was partially lost from subjects with standard disease progression. CCR6(+) T lymphocytes, regardless of their CCR7 expression, accumulated in the spleen of HIV-infected patients, where they died by apoptosis. Assessment of CCR6 expression allowed us to describe novel memory T-cell subpopulations capable of high cytokine production and provided evidence of a pathologic CCR6-dependent pathway of memory T-cell homing that may participate in the loss of memory response against infections.

Abstract
Different primings with DNA and fowlpox virus (FP) recombinants or FP alone were used in a pre-clinical trial to evaluate and compare immunogenicity and efficacy against HIV/SHIV. Three immunization regimens were tested in three groups of mice in which the SIV gag/pol and HIV-1 env transgenes were separately expressed by DNA and FP vectors, followed by VLP(SHIV) boosting. All of the protocols were effective in eliciting homologous neutralizing antibodies, although the mice immunized with DNA followed by FP recombinants or DNA+FP recombinants showed both high titres of neutralizing antibodies and high frequencies of env-specific IFNgamma-producing T lymphocytes. Vaccine efficacy, as demonstrated by growth control of env-expressing tumours, was obtained in both of these two groups of mice. These results establish a preliminary profile for the combined use of these recombinant vectors in protocols to be tested in the SHIV-macaque model of HIV-1 infection.

Abstract
BACKGROUND Strong T cell and antibody responses to human immunodeficiency virus (HIV), low virus production, and some genetic traits have been individually associated with nonprogression of HIV infection, but the best correlate with protection against disease progression remains unknown. METHODS We prospectively followed 66 untreated long-term nonprogressors and analyzed relationships between HIV-1-specific CD4 T helper (Th) 1 and CD8 T cell responses and HIV-1-specific antibodies, HIV-1 RNA and proviral DNA loads, host genes, and CD4 Th1 cell counts at entry into the study and 4 years later. RESULTS HIV-1 p24-specific CD4 Th1 cell proliferation, interferon (IFN)- gamma production, and IFN- gamma -producing cell frequencies at entry significantly and negatively correlated with HIV-1 RNA and proviral DNA loads and were independent of CD4 Th1 cell counts and host genes. HIV-1 Gag-specific IFN- gamma -producing CD8 T cell frequencies correlated with HIV-1 proviral DNA loads but not with RNA loads. Only high frequencies of HIV-1 p24-specific CD4 Th1 cells combined with HIV-1 gp41-specific IgG2 antibodies significantly predicted persistence of high CD4 Th1 cell counts. CONCLUSION HIV-1-specific CD4 Th1 responses combined with IgG2 antibodies and IFN- gamma -producing CD4 Th1 cells are better predictors of long-term nonprogression than are virus parameters, host genes, or HIV-1-specific CD4 Th1 or CD8 T cell proliferation.

Abstract
The opportunistic behavior and the potential interactions of human herpesvirus 7 (HHV-7) with human immunodeficiency virus (HIV)-1 in HIV-1-infected patients were investigated in comparison with HHV-6, another human roseolovirus. Roseolovirus DNAs were detected and quantified in peripheral blood mononuclear cells (PBMCs) from 198 HIV-seronegative healthy blood donors, 38 HIV-1-infected patients classified as long-term non-progressors, and 99 HIV-1-infected patients classified as progressors. The rate of HHV-7 DNA detection was higher in healthy donors (78%) than in long-term non-progressors (47%; P = 0.0003) or in progressors (52%; P < 0.0001). HHV-7 cell load was higher in healthy donors (median: 212 EqCop/10(6) PBMCs) and in long-term non-progressors (median: 105 EqCop/10(6) PBMCs) than in progressors (median: 48 EqCop/10(6) PBMCs; P < 0.0001 and P = 0.015, respectively). Among progressors, HHV-7 detection was correlated positively with the CD4(+) T-lymphocyte count (P = 0.028). Neither HHV-7 detection rate nor cell load was correlated with the HIV-1 plasma load. As a whole, HHV-6 detection rate and cell load were lower than the HHV-7 counterparts, albeit exhibiting similar differences between healthy donors, long-term non-progressors, and progressors. In conclusion, HHV-7 infection does not appear to be stimulated by HIV-1 infection, nor interact with it. Rather, HHV-7 detection rate and cell load reflect CD4(+) T-lymphocyte count, with higher values in healthy donors and long-term non-progressors than in progressors.

Abstract
Chemokines participate in the antitumor immune response by regulating the movement and positioning of lymphocytes as well as effector functions and may thus be candidates for use in antitumor therapy. To test whether CCL5, a chemokine involved in the recruitment of a wide spectrum of immunocompetent cells, can control tumor growth, we forced its expression at mouse tumor sites. Tumor growth was reduced in mice with s.c. syngeneic CCL5-EL-4 compared with EL-4-injected mice, whereas both reduced tumor growth and incidence were observed in mice with OVA-expressing EG-7 transfected with CCL5 compared with EG-7-injected mice. Significant antitumor effects were observed soon after intratumoral injection of DNA plasmid coding for chimeric CCL5-Ig. Importantly, quantitative RT-PCR assays showed that the amount of CCL5 expression at the tumor site determined the effectiveness of the antitumor response, which was associated with infiltration of increased numbers of NK, CD4, and CD8 cells at the tumor site. This effect was lost in mice deficient for T/B lymphocytes (RAG-2 knockout) or for CCR5 (CCR5 knockout). Together, these data demonstrate the antitumor activity of intratumoral CCL5 overexpression, due to its recruitment of immunocompetent cells, and the potential usefulness of chimeric CCL5-Ig DNA as an agent in cancer therapy.

Abstract
CX3CR1 has been described previously as a marker of human cytotoxic effector cells. We evaluated the possibility of using its ligand, CX3CL1, to redirect immune response against tumors. When murine lymphoma cell lines (EL4 and its derivative EG7) stably transfected with human-CX3CL1 were injected s.c. into C57BL/6 mice, the tumor growth was severely impaired when compared with the growth of control cell lines. This antitumor effect of CX3CL1 was also found in T- and B-cell-deficient Rag1-/- mice but vanished in natural killer (NK) cell-deficient beige mice and in CX3CR1-/- mice, suggesting the involvement of CX3CR1-expressing NK cells. In addition, increased NK cell infiltration was observed in CX3CL1-producing tumors compared with controls. The effect of CX3CR1 on tumor growth required host cytotoxic effector cell functions because both IFNgamma-/- and perforin-/- mice were resistant to CX3CL1 antitumor effect. Finally, intratumoral injection of DNA plasmid coding for a chimeric immunoglobulin presenting the CX3CL1 chemokine domain provided strong antitumor activity. Together, these data demonstrate that the CX3CL1 can reduce incidence and size of lymphoma in vivo through increased recruitment of activated NK cytotoxic cells. These findings offer the first evidence of the potential of chimeric immunoglobulin-chemokines in anticancer therapy.

Abstract
Experimental cerebral malaria (ECM) resulting from Plasmodium berghei ANKA infection involves T lymphocytes. However, the mechanisms of T cell-mediated pathogenesis remain unknown. We found that, in contrast to ECM-susceptible C57BL6 mice, perforin-deficient (PFP-KO) mice were resistant to ECM in the absence of brain lesions, whereas cytoadherence of parasitized erythrocytes and massive accumulation of activated/effector CD8 lymphocytes were observed in both groups of mice. ECM is induced in PFP-KO mice after adoptive transfer of cytotoxic CD8+ cells from infected C57BL6 mice, which were directed to the brain of PFP-KO mice. This specific recruitment might involve chemokine/chemokine receptors, since their expression was up-regulated on activated CD8 cells, and susceptibility to ECM was delayed in CCR5-KO mice. Thus, lymphocyte cytotoxicity and cell trafficking are key players in ECM pathogenesis.

Abstract
Degeneracy of the TCR repertoire might allow for cross-recognition of epitope variants. However, it is unclear how the first encounter with HIV Ags determines recognition of emerging epitope variants. This question remains crucial in the choice of HIV vaccine sequences given the virus variability. In this study, we individualized nine natural mutations within an HIV-Nef(180-189) epitope selected from several HIV-infected individuals. These variants of Nef(180-189) sequence display slightly different HLA-A2 binding capacities and stabilities and we have shown that only two induced a strong CTL response in vivo in HLA-A2 transgenic mice after a single injection. We demonstrated that priming with these two immunogenic variants generated a specific pattern of cross-reactive CTL repertoire directed against poorly immunogenic peptides. Thus, the range of peptide variants recognized by HIV-specific CTL depends upon the Ag encountered during primary immunization of CD8 lymphocytes. These data have practical implications in the development of cross-reactive vaccines against HIV.

Abstract
The involvement of Fas and caspase activation during naive T cell proliferation is still controversial. To explore this paradox, we used antigenic variation of PCC 88-104 peptide to dissect pathways of TCR signaling leading to cell proliferation. We demonstrated that strong TCR stimulation but not weak TCR stimulation induced T cell proliferation and was dependent on IETD- but independent of DEVD-specific caspases. In addition, altered TCR ligand induced T cell proliferation in the absence of IETD-, DEVD-specific caspase activities and Fas ligand expression. However, AND-TCR-transgenic mice in lpr/lpr background generated recently have no defect T cell proliferation after stimulation by the agonist peptide, demonstrating that antigen-induced T cell proliferation is independent of Fas-activation pathways. Thus, Fas-independent caspase activation is tightly regulated by the strength of antigenic stimulation during T cell proliferation. These data reveal a novel facet of antigenic caspase regulation during naive CD4 T cell proliferation and provide insights into the function of caspases during T cell homeostasis.

Abstract
Qualitative and quantitative virological parameters were investigated in 68 long-term nonprogressor (LTNP) HIV-1-infected patients and 9 slow-progressor controls. LTNP status was defined as an asymptomatic HIV infection for at least 8 years, a stability of CD4+ cell counts > or =600 cells/mm3 and no antiretroviral therapy. LTNP subjects exhibited a lower median plasma RNA load than controls (6,000 vs. 40,000 RNA copies/ ml) despite a wide range of values in both groups. When compared to the control group, LTNP subjects also exhibited a lower virus isolation rate (65% vs. 100%) and cell-associated viremia (0.75 vs. 56.8 number of infectious unit/ million cells) when CD8-depleted CD4+ cells were tested. By contrast, no major differences in virus replication properties or cell tropism were observed. After 1 year of follow-up, no major overall changes in the virological parameters was observed in the 50 LTNP subjects evaluated at this time. However, nine patients had started antiretroviral therapy, and six others had increased viral loads. Despite the progression observed during the first year of follow-up, the hypothesis that there is a specific subgroup of LTNP patients who will not develop disease cannot be ruled out as yet.

Abstract
The vigorous CTL response directed against HIV is considered to be important in reducing HIV viral load, although it is unable to stop ongoing viral replication, which generates new antigenic variants. We analyzed the impact of sequential changes in five epitopes of HIV-1 Nef on CTL recognition in four stable patients. A high rate of variation was found, and in all these patients we could detect CTL specific for 32 out of 36 autologous viral variants occurring in 5 HLA-A2- or HLA-B7-restricted Nef epitopes at two time points. Two distinct patterns for dynamics of CTL responses to viral variation were observed: 1) temporary amplification of viral variants followed by expansion of variant-specific CTL, ultimately leading to the disappearance of 12 out of the 14 initial epitope variants within two years. A second set of viral variants that had replaced the initial ones could also stimulate specific CTL precursors in the context of the same or an alternative HLA molecule; and 2) persistence of 2 viral variants in relatively conserved epitopes despite specific CTL recognition. Therefore, a remarkable flexibility of the immune system allows constant adaptation of CTL to multiple HIV variants and thus elimination of HIV variant-producing cells in slow progressors.
