Abstract
Critically ill patients manifest many of the same immune features seen in coronavirus disease 2019 (COVID-19), including both "cytokine storm" and "immune suppression." However, direct comparisons of molecular and cellular profiles between contemporaneously enrolled critically ill patients with and without severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) are limited. We sought to identify immune signatures specifically enriched in critically ill patients with COVID-19 compared with patients without COVID-19. We enrolled a multisite prospective cohort of patients admitted under suspicion for COVID-19, who were then determined to be SARS-CoV-2-positive (n = 204) or -negative (n = 122). SARS-CoV-2-positive patients had higher plasma levels of CXCL10, sPD-L1, IFN-γ, CCL26, C-reactive protein (CRP), and TNF-α relative to SARS-CoV-2-negative patients adjusting for demographics and severity of illness (Bonferroni P value < 0.05). In contrast, the levels of IL-6, IL-8, IL-10, and IL-17A were not significantly different between the two groups. In SARS-CoV-2-positive patients, higher plasma levels of sPD-L1 and TNF-α were associated with fewer ventilator-free days (VFDs) and higher mortality rates (Bonferroni P value < 0.05). Lymphocyte chemoattractants such as CCL17 were associated with more severe respiratory failure in SARS-CoV-2-positive patients, but less severe respiratory failure in SARS-CoV-2-negative patients (P value for interaction < 0.01). Circulating T cells and monocytes from SARS-CoV-2-positive subjects were hyporesponsive to in vitro stimulation compared with SARS-CoV-2-negative subjects. Critically ill SARS-CoV-2-positive patients exhibit an immune signature of high interferon-induced lymphocyte chemoattractants (e.g., CXCL10 and CCL17) and immune cell hyporesponsiveness when directly compared with SARS-CoV-2-negative patients. This suggests a specific role for T-cell migration coupled with an immune-checkpoint regulatory response in COVID-19-related critical illness.

Abstract
INTRODUCTION/AIM This study was performed to examine the proficiency of mononuclear cells (MNC) and polymorphonuclear cells (PMN) in a whole blood model to expressing interleukin-8 (IL-8) in response to various stimuli. METHODS Isolated cells that had been recombined with heparinized plasma were incubated with lipopolysaccharide (LPS), phorbol myristate acetate (PMA) and tumor necrosis factor (TNF)-alpha. RESULTS IL-8 release by MNC was most potently induced by LPS, reaching significant levels after 2-h incubation in the presence of 0.2 ng/ml LPS. In contrast, 5.0 ng/ml LPS was required for PMN to release significant amounts of the cytokine (P<0.001). When PMN and MNC were coincubated (MNC/PMN), LPS-induced IL-8 release was reduced compared to the release from MNC alone, regardless of the concentration of LPS used. IL-8 release by PMN was much more strongly induced by TNF-alpha, increasing by 1050% in the presence of 10 ng/ml TNF-alpha (P<0.005), whereas MNC or MNC/PMN subjected to this stimulus alone did not significantly enhance their IL-8 release. PMA had no effect on IL-8 release from either cell type. Since a high portion of IL-8 in blood is associated with cells, the IL-8 levels in isolated and lysed cell suspensions were also quantified. Thus, a considerably higher level of IL-8 was found in freshly isolated PMN (0.58+/-0.09 ng/ml) than in MNC (0.010+/-0.007 ng/ml). PMN remained the main source for cell-associated IL-8 after 2-h incubation in the absence of any added stimuli, harbouring a relatively high level of the cytokine (3.37+/-1.38 ng/ml), which was significantly enhanced in the presence of TNF-alpha (8.99+/-1.46 ng/ml, P<0.001). CONCLUSION This study shows that LPS is an effective inducer of IL-8 in MNC, whereas TNF-alpha is a potent agonist for IL-8 release from PMN. The main portion of cell-associated IL-8 is present in PMN when the cells are stimulated in their normal environment of plasma.

Abstract
AbstractBackground: It has been shown that a high percentage of interleukin-8 (IL-8) in blood is cell associated. Recently, a simple method for determination of cell-associated IL-8 in whole blood after cell lysis has been described. The purpose of this study was to evaluate this method, to examine the influence of preanalytic sample handling, and to establish the concentration range of total IL-8 and its relation to age and sex in healthy subjects.Methods: Total IL-8 content of whole blood was determined after lysing blood cells with Milenia® cell lysis solution. IL-8 in the resulting blood lysate was measured with the IMMULITE® IL-8 immunoassay.Results: When freshly drawn blood was stored up to 48 h on ice, no significant changes in total IL-8 were measured in the subsequently prepared lysate, whereas with storage at room temperature, total IL-8 increased after 3 h from 94 ± 13 ng/L to 114 ± 16 ng/L (n = 10). In lysate stored for 48 h at 4 °C, marginal changes of the IL-8 concentration were noted, with storage at room temperature, only 76% ± 5% (n = 12) of initial concentration was recovered. From lysate frozen at −20 and −80 °C, respectively, 84% ± 4% and 93% ± 2% of initial IL-8 was recovered after 70 days (n = 10). IL-8 was measured with comparable precision in plasma (CV, 3.2–4.2%) and blood lysate (CV, 3.7–4.1%). When plasma was diluted with cell lysis solution, a slightly overestimated recovery (125% ± 3%) was observed; for lysate specimens with a cell lysis solution content ≥75%, the recovery after dilution was 98% ± 2%. In lysate prepared from 12 blood samples with exogenous IL-8 added, IL-8 recovery was 104% ± 2% (recovery from plasma <35%). The median total IL-8 in blood lysates from 103 healthy subjects (22–61 years) was 83 ng/L of blood (2.5–97.5 percentile range, 49–202 ng/L of blood). In females but not in males, total IL-8 increased significantly with advancing age (P <0.002). We found grossly increased total IL-8 in six pregnant women with amniotic infection syndrome.Conclusions: The evaluated method allows the assessment of total IL-8 in blood with good performance when appropriate conditions of sample pretreatment are considered. The values in healthy volunteers all were above the detection limit of the IL-8 assay; therefore, slight changes of total IL-8 could be noted. Thus, the present method is a suitable tool to study the diagnostic relevance of total IL-8 in blood.

Abstract
Abstract
We have previously shown that low dose melphalan (l-phenylalanine mustard; l-PAM) therapy of hitherto immunosuppressed mice bearing a large (20-mm) s.c. MOPC-315 tumor leads to the acquisition of potent CD8+ T cell-mediated antitumor immunity which in turn eradicates the large tumor burden not eradicated by the direct antitumor effects of the drug. Here we show the preferential importance of the B7-2 costimulatory molecule for the curative effectiveness of low dose l-PAM for mice bearing a large MOPC-315 tumor by demonstrating that treatment with anti-B7-2 mAb, but not anti-B7-1 mAb, reduced the percentage of mice cured by the low dose l-PAM. In addition, we show the preferential importance of the B7-2 molecule for the low dose l-PAM-induced acquisition of the ability of tumor-infiltrating lymphocytes from MOPC-315 tumor bearers to secrete IL-2 and IFN-γ as well as to exert an anti-MOPC-315 CTL effect. The preferential importance of the B7-2 molecule may be due to the higher level of B7-2 than of B7-1 expression on B220+ cells and on tumor cells from the s.c. tumor nodule of low dose l-PAM-treated MOPC-315 tumor bearers and the selective up-regulation of the B7-2 molecule in the draining of these mice. Thus, the B7-2 molecule plays a dominant role in the acquisition of T cell-dependent tumor-eradicating immunity in low dose l-PAM-treated mice bearing a large MOPC-315 tumor, suggesting that one of the mechanisms by which chemotherapy may enhance antitumor immunity is through up-regulation of critical costimulatory molecules that enhance antitumor responses.

Abstract
In inflammatory and infectious diseases, the presence of circulating cytokines in plasma strongly suggests, following their exacerbated production, that saturation of specific binding sites has occurred or that an equilibrium between receptor-bound and free cytokines has been reached. In this report, we demonstrate that in addition to circulating interleukin-8 (IL-8), high levels of cell-associated IL-8 were detected in blood samples from patients with sepsis syndrome. The following analysis will reveal that in addition to erythrocytes, which have been dubbed a "sink" for IL-8, peripheral blood mononuclear cells (PBMC) and polymorphonuclear cells (PMN) contributed to the detection of cell-associated IL-8. On a per cell basis, 2,000 to 7,000 times the amount of IL-8 was found associated with PMN than with erythrocytes. In addition, circulating cells may well be the source of the leukocyte-associated form of IL-8. Similarly, in vitro experiments, such as whole-blood stimulation assays or the addition of exogenous IL-8 in blood samples, demonstrated that a large proportion of the IL-8 was associated with leukocytes. This suggests that the trapping of free cytokines onto the cell surface and the internalization of the IL-8 bound to its receptor, occurring both in vitro and in vivo, allows the detection of this cell-associated form. This analysis of cell-associated cytokines was extended to IL-1ra, another component of the inflammatory response, which, in contrast to IL-8, has been demonstrated to exist as an intracellular form. Indeed, cell-associated IL-1ra was also detected in septic patients. The measurement of cell-associated proinflammatory and anti-inflammatory cytokines in patients is clearly a more reliable reflection of their production than is the simple measurement in plasma and may provide useful indication to further understand the inflammatory process.
