Abstract
Nutrition is emerging as a promising therapeutic tool to modulate the immune system in health and disease. We propose that the timing of dietary interventions is probably what determines their success. In this context, we explore recent research that identifies the early phases of dietary intervention as critical time windows for modulating immunity and optimizing cancer therapy. Furthermore, we highlight how the timing of intervention can yield different outcomes. The data suggest that nutrient availability and absorption over a short period can significantly impact mammalian immune and even non-immune landscapes. This, in turn, can lead to changes in mucosal and systemic immunity, potentially exacerbating or ameliorating inflammation, and perhaps influencing tumor cells and their response to cancer therapies.

Abstract
Omnivorous animals, including mice and humans, tend to prefer energy-dense nutrients rich in fat over plant-based diets, especially for short periods of time, but the health consequences of this short-term consumption of energy-dense nutrients are unclear. Here, we show that short-term reiterative switching to 'feast diets', mimicking our social eating behavior, breaches the potential buffering effect of the intestinal microbiota and reorganizes the immunological architecture of mucosa-associated lymphoid tissues. The first dietary switch was sufficient to induce transient mucosal immune depression and suppress systemic immunity, leading to higher susceptibility to Salmonella enterica serovar Typhimurium and Listeria monocytogenes infections. The ability to respond to antigenic challenges with a model antigen was also impaired. These observations could be explained by a reduction of CD4+ T cell metabolic fitness and cytokine production due to impaired mTOR activity in response to reduced microbial provision of fiber metabolites. Reintroducing dietary fiber rewired T cell metabolism and restored mucosal and systemic CD4+ T cell functions and immunity. Finally, dietary intervention with human volunteers confirmed the effect of short-term dietary switches on human CD4+ T cell functionality. Therefore, short-term nutritional changes cause a transient depression of mucosal and systemic immunity, creating a window of opportunity for pathogenic infection.

Abstract
A role of CD4+ T cells during the progression from nonalcoholic fatty liver disease (NAFLD) to nonalcoholic steatohepatitis (NASH) has been suggested, but which polarization state of these cells characterizes this progression and the development of fibrosis remain unclear. In addition, a gut-liver axis has been suggested to play a role in NASH, but the role of CD4+ T cells in this axis has just begun to be investigated. Combining single-cell RNA sequencing and multiple-parameter flow cytometry, we provide the first cell atlas to our knowledge focused on liver-infiltrating CD4+ T cells in patients with NAFLD and NASH, showing that NASH is characterized by a population of multicytokine-producing CD4+ T cells. Among these cells, only those with a Th17 polarization state were enriched in patients with advanced fibrosis. In parallel, we observed that Bacteroides appeared to be enriched in the intestine of NASH patients and to correlate with the frequency of multicytokine-producing CD4+ T cells. In short, we deliver a CD4+ T cell atlas of NAFLD and NASH, providing the rationale to target CD4+ T cells with a Th17 polarization state to block fibrosis development. Finally, our data offer an early indication to test whether multicytokine-producing CD4+ T cells are part of the gut-liver axis characterizing NASH.

Abstract
The molecular basis of the persistence of experienced T lymphocytes, also known as "memory T lymphocytes," is still enigmatic. We are beginning to understand their considerable heterogeneity and topographic compartmentalization into memory T cells circulating through the body and those residing in a particular tissue. In some tissues, like murine spleen, subpopulations of memory T cells proliferating in the absence of antigen (homeostatic proliferation) have been described. Other populations are maintained resting in terms of transcription, mobility, and proliferation in dedicated survival niches organized by stromal cells. The survival of these memory T cells is conditional on being in such a niche, where they can persist for a lifetime. Circulating memory T lymphocytes of distinct immune responses slowly decline in numbers over time. The rules governing their entry into and exit from blood, as well as their lifestyle outside of the blood and their relation to resident memory T cells are poorly understood. Homeostasis of circulating, proliferating, and resting memory T cells is obviously controlled by different rheostats: tissue-exit and tissue-entry signals for circulating and proliferation-inducing signals for proliferating memory T cells. For tissue-resident, resting memory T cells, it is the availability of their survival niche. Apparently, this mechanism (i.e., the link between memory T cell and stromal cell) is so robust that it provides efficient T-cell memory over a lifetime in tissues such as the bone marrow.

Abstract
Hyperinflammation contributes to lung injury and subsequent acute respiratory distress syndrome (ARDS) with high mortality in patients with severe coronavirus disease 2019 (COVID-19). To understand the underlying mechanisms involved in lung pathology, we investigated the role of the lung-specific immune response. We profiled immune cells in bronchoalveolar lavage fluid and blood collected from COVID-19 patients with severe disease and bacterial pneumonia patients not associated with viral infection. By tracking T cell clones across tissues, we identified clonally expanded tissue-resident memory-like Th17 cells (Trm17 cells) in the lungs even after viral clearance. These Trm17 cells were characterized by a a potentially pathogenic cytokine expression profile of IL17A and CSF2 (GM-CSF). Interactome analysis suggests that Trm17 cells can interact with lung macrophages and cytotoxic CD8+ T cells, which have been associated with disease severity and lung damage. High IL-17A and GM-CSF protein levels in the serum of COVID-19 patients were associated with a more severe clinical course. Collectively, our study suggests that pulmonary Trm17 cells are one potential orchestrator of the hyperinflammation in severe COVID-19.

Abstract
Isolation of cells from organs and tissues represents a challenge for many researchers. Cell yield, purity, and cell death are common problems associated with it, which greatly affect experimental results in terms of reproducibility and biological observations. Here, we describe state-of-the-art protocols of how to isolate CD4+ T cells from both human and murine organs and tissues, reducing at minimum cell death, while increasing at the same time cell yield and purity.

Abstract
CD4+ T helper (TH) cells are key mediators of immunity, and according to their effector functions, they can be divided into different subsets, namely, TH1, TH2, TH17, and TH22. In order to maintain systemic homeostasis and peripheral tolerance, CD4+ TH cells are counterbalanced by CD4+ T cells with regulatory properties, namely, Foxp3+ regulatory T cells (Foxp3+TREG) and TR1 cells. Here, we describe how to in vitro differentiate murine naïve CD4+ T cells toward helper (TH1, TH2, TH17, and TH22) and regulatory (Foxp3+TREG and TR1) cells.

Abstract
At present, it is not clear how memory B lymphocytes are maintained over time, and whether only as circulating cells or also residing in particular tissues. Here we describe distinct populations of isotype-switched memory B lymphocytes (Bsm) of murine spleen and bone marrow, identified according to individual transcriptional signature and B cell receptor repertoire. A population of marginal zone-like cells is located exclusively in the spleen, while a population of quiescent Bsm is found only in the bone marrow. Three further resident populations, present in spleen and bone marrow, represent transitional and follicular B cells and B1 cells, respectively. A population representing 10-20% of spleen and bone marrow memory B cells is the only one qualifying as circulating. In the bone marrow, all cells individually dock onto VCAM1+ stromal cells and, reminiscent of resident memory T and plasma cells, are void of activation, proliferation and mobility.

Abstract
Abstract
Despite the overall success of T-cell based immunotherapies, the number of patients that benefit is still lower than expected. Invariant Natural Killer T cells (iNKTs) offer an alternative and appealing therapeutic platform owing to their intrinsic features and independence from MHC restriction. In two mouse models, mirroring prostate or colon cancer, iNKTs play strikingly opposite roles, either promoting a TH1-skewed anti-tumor response, or fostering tumor progression with TR1-oriented status. The tepid results of iNKT cell-based therapies could reflect a thus far unappreciated plastic conversion of inflammatory iNKTs into regulatory NKT10 within the tumor’s microenvironment.
This study aims to elucidate the occurrence and the dynamics of the inflammatory-to-regulatory iNKT cell plasticity in solid tumors, to clarify the environmental cues triggering their conversion and the molecular mechanisms that govern it. By employing innovative multi-cytokine reporter and fate mapping mice, we reliably detected iNKTs actively switching from producing IFNγ (exNKT1) to producing IL10, in the context of colon polyposis. Further analyses aim to unravel the molecular mechanisms of iNKT cell plasticity and to investigate the contribution of the tumor-specific microbial component.
The currently incomplete understanding of iNKT cell plasticity is dampening the appropriate use of these powerful cells in therapeutic settings. As such, clinical protocols employing iNKTs for treating cancer have so far achieved only modest results. By addressing the molecular mechanisms underlying NKT10 conversion, we are likely to find pathways that can be targeted to fully unleash the anti-tumor power of these innate-like T cells in immunotherapy.

Abstract
It is a matter of current debate whether the bone marrow is a hub for circulating memory T lymphocytes and/or the home of resident memory T lymphocytes. Here we demonstrate for CD69+ murine CD8+ , and CD69+ murine and human CD4+ memory T lymphocytes of the bone marrow, making up between 30 and 60% of bone marrow memory T lymphocytes, that they express the gene expression signature of tissue-resident memory T lymphocytes. This suggests that a substantial proportion of bone marrow memory T lymphocytes are resident. It adds to previous evidence that bone marrow memory T cells are resting in terms of mobility and proliferation, and maintain exclusive long-term memory to distinct, systemic antigens.

Abstract
Dietary habits have a profound impact on intestinal homeostasis and in general on human health. In Western countries, high intake of calories derived from fried products, butter and processed meat is favored over dietary regimens rich in fruits and vegetables. This type of diet is usually referred to as Western-type diet (WTD) and it has been associated with several metabolic and chronic inflammatory conditions of the gastrointestinal tract. In this review, we describe how WTD promotes intestinal and extra-intestinal inflammation and alters mucosal immunity acting on CD4+ T cells in a microbiota-dependent or –independent fashion, ultimately leading to higher susceptibility to infectious and autoimmune diseases. Moreover, summarizing recent findings, we propose how dietary supplementation with fiber and vitamins could be used as a tool to modulate CD4+ T cell phenotype and function, ameliorating inflammation and restoring mucosal homeostasis.

Abstract
In T lymphocytes, expression of miR-148a is induced by T-bet and Twist1, and is specific for pro-inflammatory Th1 cells. In these cells, miR-148a inhibits the expression of the pro-apoptotic protein Bim and promotes their survival. Here we use sequence-specific cholesterol-modified oligonucleotides against miR-148a (antagomir-148a) for the selective elimination of pro-inflammatory Th1 cells in vivo. In the murine model of transfer colitis, antagomir-148a treatment reduced the number of pro-inflammatory Th1 cells in the colon of colitic mice by 50% and inhibited miR-148a expression by 71% in the remaining Th1 cells. Expression of Bim protein in colonic Th1 cells was increased. Antagomir-148a-mediated reduction of Th1 cells resulted in a significant amelioration of colitis. The effect of antagomir-148a was selective for chronic inflammation. Antigen-specific memory Th cells that were generated by an acute immune reaction to nitrophenylacetyl-coupled chicken gamma globulin (NP-CGG) were not affected by treatment with antagomir-148a, both during the effector and the memory phase. In addition, antibody titers to NP-CGG were not altered. Thus, antagomir-148a might qualify as an effective drug to selectively deplete pro-inflammatory Th1 cells of chronic inflammation without affecting the protective immunological memory. Th1 cells expressing miR-148a mediate colitis in a murine model of IBD. Antagomir-148a inhibits colitis by selectively depleting Th1 cells from the colon. Antagomir-148a does not affect the protective immunological memory.

Abstract
OBJECTIVE Malignant ovarian germ cell tumors (MOGCT) carry an excellent prognosis, and the treatment aims to achieve results with the least possible treatment-related morbidity. The aim of this study was to assess the outcomes of pediatric patients with MOGCT. METHODS Patients were treated according to their stage: surgery and surveillance for stage I; a modified bleomycin-etoposide-cisplatin (BEP) regimen for stages II (three cycles), III, and IV (three cycles) with surgery on residual disease. RESULTS Seventy-seven patients were enrolled (median age 11.8 years), 26 with dysgerminoma (Dysg), 13 with immature teratoma and elevated serum alpha-fetoprotein levels (IT + AFP), and 38 with nondysgeminoma (Non-Dysg) staged as follows: 27 stage I, 13 stage II, 32 stage III, 5 stage IV. Among evaluable patients in stage I (5-year event-free survival [EFS] 72.1% [95% CI: 56.4-92.1%]; 5-year overall survival [OS] 100%), seven relapsed (three patients with Dysg and four patients with Non-Dysg) and were rescued with chemotherapy (plus surgery in three patients). Among the evaluable patients with stages II-IV, 48 (98%) achieved complete remission after chemotherapy ± surgery, one (IT + AFP, stage IV) had progressive disease. In the whole series (median follow-up 80 months), the 5-year OS and EFS were 98.5% (95% CI: 95.6-100%) and 84.5% (95% CI: 76.5-93.5%). CONCLUSIONS We confirm the excellent outcome for MOGCT. Robust data are lacking on surgical staging, surveillance for Non-Dysg with stage I, the management of IT + AFP, and the most appropriate BEP regimen. As pediatric oncologists, we support the role of surveillance after proper surgical staging providing cases are managed by experts at specialized pediatric centers.

Abstract
It is current belief that numbers of CD8+ memory T lymphocytes in the memory phase of an immune response are maintained by homeostatic proliferation. Here, we compare the proliferation of CD8+ memory T lymphocytes, generated by natural infections and by intentional immunization, in spleen and bone marrow (BM). Fifty percent of CD8+ memory T lymphocytes in the spleen are eliminated by cyclophosphamide within 14 days, indicating that numbers of at least 50% of splenic CD8+ memory T lymphocytes are maintained by proliferation. The numbers of CD8+ memory T lymphocytes in the BM, however, were not affected by cyclophosphamide. This stability was independent of circulating CD8+ memory T cells, blocked by FTY720, showing that BM is a privileged site for the maintenance of memory T lymphocytes, as resident cells, resting in terms of proliferation.

Abstract
Conflicting evidence has been provided as to whether induction of intestinal inflammation by adoptive transfer of naïve T cells into Rag-/- mice requires expression of the transcription factor T-bet by the T cells. Here, we formally show that the intestinal microbiota composition of the Rag-/- recipient determines whether or not T-bet-deficient Th cells can induce colitis and we have resolved the differences of the two microbiomes, permissive or non-permissive to T-bet-independent colitis. Our data highlight the dominance of the microbiota over particular T cell differentiation programs in the pathogenesis of chronic intestinal inflammation.

Abstract
INTRODUCTION Despite the broad spectrum of antirheumatic drugs, RA is still not well controlled in up to 30-50 % of patients. Inhibition of JAK kinases by means of the pan-JAK inhibitor tofacitinib has demonstrated to be effective even in difficult-to-treat patients. Here, we discuss whether the efficacy of JAK inhibition can be improved by simultaneously inhibiting SYK kinase, since both kinases mediate complementary and non-redundant pathways in RA. METHODS Efficacy of dual JAK + SYK inhibition with selective small molecule inhibitors was evaluated in chronic G6PI-induced arthritis, a non-self-remitting and destructive arthritis model in mice. Clinical and histopathological scores, as well as cytokine and anti-G6PI antibody production were assessed in both preventive and curative protocols. Potential immunotoxicity was also evaluated in G6PI-induced arthritis and in a 28-day TDAR model, by analysing the effects of JAK + SYK inhibition on hematological parameters, lymphoid organs, leukocyte subsets and cell function. RESULTS Simultaneous JAK + SYK inhibition completely prevented mice from developing arthritis. This therapeutic strategy was also very effective in ameliorating already established arthritis. Dual kinase inhibition immediately resulted in greatly decreased clinical and histopathological scores and led to disease remission in over 70 % of the animals. In contrast, single JAK inhibition and anti-TNF therapy (etanercept) were able to stop disease progression but not to revert it. Dual kinase inhibition decreased Treg and NK cell counts to the same extent as single JAK inhibition but overall cytotoxicity remained intact. Interestingly, treatment discontinuation rapidly reversed such immune cell reduction without compromising clinical efficacy, suggesting long-lasting curative effects. Dual kinase inhibition reduced the Th1/Th17 cytokine cascade and the differentiation and function of joint cells, in particular osteoclasts and fibroblast-like synoviocytes. CONCLUSIONS Concurrent JAK + SYK inhibition resulted in higher efficacy than single kinase inhibition and TNF blockade in a chronic and severe arthritis model. Thus, blockade of multiple immune signals with dual JAK + SYK inhibition represents a reasonable therapeutic strategy for RA, in particular in patients with inadequate responses to current treatments. Our data supports the multiplicity of events underlying this heterogeneous and complex disease.

Abstract
Isolated torsion of fallopian tube, meanwhile uncommon, should be considered in diagnosis of pelvic and lower abdominal pain. US investigation is an useful diagnostic tool. A prompt diagnosis could avoid salpingectomy and preserve fertility. Laparoscopy, as the first approach, should be preferred. We report a case of isolated tubal torsion occurring in a premenarcheal girl successfully managed by laparoscopy.

Abstract
Intestinal atresia type III B (apple peel) and gastroschisis are both congenital malformations who require early surgical correction in neonatal age. Their association is very rare. We present the case of a full term infant with partial apple peel ileal atresia and a small defect of the anterior abdominal wall, complicated by in utero intestinal perforation and subsequent meconial peritonitis. We observed a partial atresia of small intestine, with involvement of terminal ileus savings of jejunum and a large part of the proximal ileum, small anterior abdominal wall defect with herniation of few bowel loops, intestinal malrotation. Paralytic ileus and infections are the main causes of morbidity and mortality at neonatal age. In our case, in spite of the mild phenotype, prognosis has been complicated by the onset of functional bowel obstruction, caused by chemical peritonitis resulting from contact with either amniotic fluid and meconium.

Abstract
BACKGROUND Despite the large number of children with reflux, management among urologists is still controversial. One of the most debated aspects is the choice between observation treatment or surgical treatment. METHODS We assessed the natural course of children with vesico-ureteral reflux in the period 1990-1995, to correlate factors and identify patients with high risk of renal damage. We retrospectively reviewed the clinical course of 80 children with vesicoureteral reflux. Thirty-two were diagnosed during prenatal ultrasound scan. In the other cases urologic evaluation was requested because of urinary tract infections. The following data were analyzed: medical records, diagnostic and follow-up cystogram, renal imaging, medical therapy or surgical treatment carried out according to the reflux grade, diagnostic age, congenital reflux nephropathy or postnatal acquired scarring, voiding patterns, spontaneous resolution during medical management. Follow up ranged from 5 to 10 years. RESULTS Vesicoureteral reflux resolved spontaneously in 29 patients: 25 were affected from moderate reflux, 4 from IV grade reflux. Surgical correction was carried out in 32 patients. Endoscopic treatment was performed in 25. Twenty-two children are still receiving prophylaxis and 12 were lost to follow-up. Congenital renal pathology correlate with poor outcome. CONCLUSIONS The conclusion is drawn that there is a wide clinical variability in children with vescicoureteral reflux. The most important is host's susceptibility to urinary tract infection, but the severity of reflux, age of patients and congenital reflux nephropathy influence prognosis and long-term outcome.

Abstract
BACKGROUND AND OBJECTIVES Fibrosarcoma is a rare soft tissue sarcoma (STS) that has two peaks of incidence in pediatric patients: one in infants and young children (infantile fibrosarcoma), another in older children ("adult type" fibrosarcoma). The purpose of this study was to describe the clinical features and the treatment results in patients affected by fibrosarcoma enrolled in two consecutive studies run by the STS-Italian Cooperative Group (ICG) between 1979 and 1995. PATIENTS AND METHODS Twenty-five evaluable patients were grouped according the intergroup rhabdomyosarcoma staging (IRS) system: 12 Gr I, 5 Gr II, 8 Gr III. The cut-off point between the two forms was considered the age of 2 years: 14 patients were affected by infantile and 11 by adult type of fibrosarcoma. The therapeutic guidelines were not strict and not different for the two forms: patients with initial macroscopic excision (Gr I-II) were given IVA or VAC; Gr III had VAC or VAIA and subsequent excision, if feasible. Radiation therapy (RT) was delivered in patients > 3 years with microscopic (42 Gy) and macroscopic (54 Gy) residuals. RESULTS Thirteen patients are alive without evidence of disease: 10 in first complete remission (CR), 7 Gr I, 1 Gr II, 2 Gr III, 3 in second CR after local relapse (LR) (2 Gr I, 1 Gr II). Two Gr I patients are alive with metastatic relapse. Nine patients died: six of progressive disease (PD) (three Gr II, three Gr III), two because of a second tumor (one Gr I, one Gr III) and one because of other causes (Gr III). One Gr III patient was lost at follow up, 2 years from diagnosis. The 10 years overall survival (OS) is 67.4% and the progression-free survival (PFS) is 52.2%. The OS for patients < 2 years is 78.6% (11 of 14), versus 51% for patients > 2 years (5 of 11). CONCLUSIONS The complete excision at diagnosis was the treatment of choice and was related to the best outcome. Microscopical residuals were difficult to treat with chemo-radiotherapy in both forms of fibrosarcoma. Neoadjuvant chemotherapy (CT) obtained a partial remission (PR) only in three of eight cases, while no conclusions concerning the efficacy of CT for infantile forms are possible. Patients < 2 years had a better outcome than the older ones: most of them had a tumor on extremities which was excised at diagnosis.

Abstract
PURPOSE To determine whether resection of primary tumor has a favorable influence on outcome of infants (age 0 to 11 months) with stage IV-S neuroblastoma. PATIENTS AND METHODS Between March 1976 and December 1993, 97 infants with previously untreated neuroblastoma diagnosed in 21 Italian institutions were classified as having stage IV-S disease. Seventy percent were younger than 4 months. Adrenal was the primary tumor site in 64 of 85 patients with a recognizable primary tumor. Liver was the organ most often infiltrated by the tumor (82 patients), followed by bone marrow and skin. RESULTS The overall survival (OS) rate at 5 years in 80% and event-free survival (EFS) rate 68%. In 24 infants, the effect of resection of primary tumor could not be evaluated because of rapidly fatal disease progression (n = 8), absence of a primary tumor (n = 12), or partial resection (n = 4). Of 73 assessable patients, 26 underwent primary tumor resection at diagnosis: one died of surgical complications, one relapsed locally and died, and two others relapsed (one of these two locally) and survived, for a 5-year OS rate of 92% and EFS rate of 84%. Of the remaining 47 patients who did not undergo primary tumor resection at diagnosis 11 suffered unfavorable events, of whom five died, for an OS rate of 89% and EFS rate of 75% (no significant difference from previous group). Disease recurred at the primary tumor site in only one five who died, and in only one of six survivors of progression or relapse; in these patients, the primary tumor, located in the mediastinum, was successfully resected. CONCLUSION Infants who underwent resection of the primary tumor at diagnosis had no better outcome than those in whom the decision was made not to operate.
