Additionally, circulating cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells were activated with the up-regulated surface expressions of human leucocyte antigen DR (HLA-DR) and CX3CR1 in HSPN patients with severe proteinuria. Renal biopsies demonstrated increased number of CD8

cells and/or CD56

cells and up-regulated expression of glomerular CX3CL1, a specific ligand for CX3CR1, along with increased serum CX3CL1 level.

Activated CTLs and NK cells play roles in the development of nephritis in IgAV/HSP patients and can be used as novel biomarkers for HSPN.

Eosinophilic oesophagitis (EoE) is characterised by oesophageal inflammation, fibrosis and dysfunction. Micro (mi)-RNAs interfere with pro-inflammatory and pro-fibrotic transcriptional programs, and miR-223 was upregulated in oesophageal mucosal biopsy specimens from EoE patients. The therapeutic potential of modulating miR-223 expression

has not been determined. We aimed to elucidate the relevance of oesophageal miR-223 expression in an

model of EoE by inhibiting miR-223 tissue expression.

The expression of miR-223 and the validated miR-223 target insulin-like growth factor receptor 1 (IGF1R) protein was determined in our paediatric cohort of EoE patients. A murine model of

-induced EoE was employed, and oesophagi were assessed for miR-233, IGF1R, T lymphocyte type 2 (T2) cytokine expression and eosinophil infiltration. Mice were treated with antagomirs targeting miR-223 or resveratrol targeting its upstream regulator Midline-1(MID-1).

There was an inverse relationship between an increased exprnducing ligand and MID-1 in an experimental model. These studies highlight a potentially critical role of miRNA function in EoE aetiology. miR-223 expression in the oesophagus may be therapeutically modulated by resveratrol, providing a potential new therapeutic option to be explored in EoE patients for this increasingly prevalent condition.

CD4

T cells are critical mediators of immunity to

spp. infection, but their characteristics during malarial episodes and immunopathology in naturally infected adults are poorly defined. Flow cytometric analysis of PBMCs from patients with either

or

malaria revealed a pronounced population of CD4

T cells co-expressing very high levels of CD4 and CD38 we have termed CD4

CD38

T cells. We set out to gain insight into the function of these novel cells.

CD4

T cells from 18 patients with

or

malaria were assessed by flow cytometry and sorted into populations of CD4

CD38

or CD4

T cells. Gene expression in the sorted populations was assessed by qPCR and NanoString.

CD4

CD38

T cells expressed high levels of

mRNA and canonical type 1 regulatory T-cell (TR1) genes including

,

,

and

(TIM3), and other genes with relevance to cell migration and immunomodulation. These cells increased in proportion to malaria disease severity and were absent after parasite clearance with antiimmunity and immunopathology during malaria.

Dendritic cells play a pivotal but still enigmatic role in the control of tumor development. Composed of specialised subsets (cDC1s, cDC2s, pDCs), DCs are critical in triggering and shaping antitumor immune responses. Yet, tumors exploit plasticity of DCs to subvert their functions and escape from immune control. This challenging controversy prompted us to explore the pathophysiological role of cDCs and pDCs in melanoma, where their precise and coordinated involvement remains to be deciphered.

We investigated in melanoma patients the phenotypic and functional features of circulating and tumor-infiltrating BDCA1

cDC2s, BDCA2

pDCs and BDCA3

cDC1s and assessed their clinical impact.

Principal component analyses (PCA) based on phenotypic or functional parameters of DC subsets revealed intra-group clustering, highlighting specific features of DCs in blood and tumor infiltrate of patients compared to healthy donors. DC subsets exhibited perturbed frequencies in the circulation and actively infiltrated td help designing new therapeutic strategies exploiting the potentialities of these powerful immune players and their cross-talks, while counteracting their skewing by tumors, to achieve immune control and clinical success.Plexiform schwannoma (PS) is a benign tumour of the peripheral nerve sheath that is typically found in the skin. Fewer than 15 cases of visceral PS have been reported to date in both adults and children. We herein discuss a series of 3 patients (2 male and 1 female) with abdominal PS, aged 10-16 years (mean age, 12 years). All the patients had an acute presentation with abdominal pain, which was associated with rectal bleeding in 1 case and with walking difficulties in 1 case. Radiological investigations included abdominal magnetic resonance imaging (MRI) and computed tomography, along with neurofibromatosis screening (cerebral MRI and dermatological evaluation). Complete removal of the mass was possible in 2 of the patients (in 1 case by laparoscopically assisted surgery). Follow-up was uneventful. Abdominal PS is a rare occurrence. Due to its possible association with neurofibromatosis, the diagnosis of PS should prompt an investigation for other manifestations of this disorder.Clinical evidence regarding eribulin treatment for patients with soft tissue sarcoma (STS) is limited to those with L-sarcoma (leiomyosarcoma and liposarcoma) who have completed at least two chemotherapies. Whether histological subtypes and treatment lines affect the efficacy and safety of eribulin for patients with STS has yet to be elucidated. The current study retrospectively reviewed patients with STS receiving eribulin at the Cancer Institute Hospital of JFCR and evaluated the prognostic factors affecting its efficacy and safety by histological diagnoses and treatment lines. A total of 41 patients with STS, including 26 with L-sarcoma, underwent eribulin treatment. Additionally, a total of and 14 patients, including 12 with L-sarcoma, received eribulin as a second-line treatment. The results revealed that patients with L-sarcoma demonstrated longer progression-free survival (PFS) rates compared with patients without L-sarcoma (4.5 vs. 2.3 months; P=0.005). Furthermore, differences in treatment line significantly affected PFS (4.5 months in second-line treatment vs. 2.4 months in later lines; P=0.037). A high number of patients with L-sarcoma received eribulin as a second-line treatment. Regarding safety, several adverse events were reported, such as neutropenia, which were more frequently observed in patients with L-sarcoma or other patients receiving eribulin as a second-line treatment. However, most adverse events were tolerable. The clinical efficacy of eribulin was increased in patients with L-sarcoma, which was similar to previous clinical trials. However, treatment lines could also affect its efficacy. When evaluating the clinical value of eribulin to STS, it is important to consider treatment lines.The present study assessed the safety of outpatient oral anticancer chemotherapeutic drugs by investigating the type and frequency of serious adverse effects (SAEs). Emergency hospitalization, unplanned consultations and telephone calls were investigated in 1,832 patients who received oral anticancer drug treatment at the National Cancer Center Hospital East between December 1, 2014 and November 30, 2015. Oral cytotoxic anticancer and molecular targeted drugs were administrated to 1,140 (62.2%) and 692 (37.8%) patients, respectively. A total of 52 (2.8%) SAEs were reported, with 32 (2.8%) occurring following cytotoxic anticancer drug administration and 20 (2.9%) occurring after molecular targeted drug treatment. The most common SAE was gastrointestinal toxicity. The median time to SAE occurrence was 32 days (range, 5-1,705 days). The rate of unplanned consultations and telephone calls were 5.5 and 37.9% among all patients, respectively, with skin reactions being the most common reason for unplanned consultations. SAEs often occurred early after treatment initiation. It was concluded that measures against gastrointestinal toxicity are particularly important were administering chemotherapeutic agents.The present study aimed to evaluate clinical outcomes in patients with surgically resected non-small cell lung cancer (NSCLC) with anaplastic lymphoma kinase (ALK)-rearranged mutations. A matched-pair analysis in completely resected ALK-rearranged NSLC patients and those with neither ALK nor epidermal growth factor receptor (EGFR) mutations diagnosed at 11 institutes was performed between April 2008 and March 2019. A total of 51 patients with surgically resected ALK-rearranged NSCLC were included. Women constituted 68.6%, and smokers 29.4%. The median age was 65 years. In matched-pair analysis, disease-free survival and overall survival did not differ between patients with ALK-rearranged mutations and those without mutations. Post-recurrence survival in patients with ALK mutations was longer than that of patients with neither ALK nor epidermal growth factor receptor mutations. ALK genetic testing should be performed, even in elderly patients with NSCLC. Syrosingopine research buy Favorable prognosis might be expected after appropriate treatment for patients with recurrent ALK-mutated disease.Nodular fasciitis is a mesenchymal lesion, which has been viewed as a reactive process. The MYH9-USP6 fusion gene was recently detected in nodular fasciitis, and nodular fasciitis is now considered to be a self-limiting neoplastic process. Recently, a case of nodular fasciitis that recurred a number of times and metastasized to soft tissues was reported, and the features of aggressive cases of nodular fasciitis are currently under investigation. Here, a case of locally aggressive nodular fasciitis is presented, in which the lesion grew rapidly and caused ulnar nerve palsy. The lesion was locally controlled via marginal excision, and no metastasis was identified at 24 months post-operation. Histologically, the lesion was consistent with nodular fasciitis, and the detection of the MYH9-USP6 fusion gene supported the diagnosis. Although most nodular fasciitis lesions are benign, some may be locally aggressive or even metastasize. In the case outlined in the present study, marginal excision was sufficient to locally control the lesion.The novel coronavirus called "Severe Acute Respiratory Syndrome Coronavirus 2" (SARS-CoV-2) caused an outbreak in December 2019, starting from the Chinese city of Wuhan, in the Hubei province, and rapidly spreading to the rest of the world. Consequently, the World Health Organization (WHO) declared that the coronavirus disease of 2019 (COVID-19) can be characterized as a pandemic. During COVID-19 several immunological alterations have been observed in plasma of severe patients, inflammatory cytokines are at a much higher concentration ("cytokine storm"). These aspects are associated with pulmonary inflammation and parenchymal infiltrates with an extensive lung tissue damage in COVID-19 patients. To date, clinical evidence and guidelines based on reliable data and randomized clinical trials (RCTs) for the treatment of COVID-19 are lacking. In the absence of definitive management protocols, many treatments are currently being evaluated worldwide. Some of these options were soon abandoned due to ineffectiveness, while others showed promising results.
