Ficolin-1 is upregulated in leukocytes and glomeruli from microscopic polyangiitis patients

ABSTRACT: To search for new markers of active lesions that might help better understand the molecular basis of MPA and aid in its diagnosis, DNA microarray analysis was performed with peripheral blood mononuclear cells (PBMCs).

Ficolin-1 is upregulated in leukocytes and glomeruli from microscopic polyangiitis patients

Project description:To search for new markers of active lesions that might help better understand the molecular basis of MPA and aid in its diagnosis, DNA microarray analysis was performed with peripheral blood mononuclear cells (PBMCs). A total of 12 sets of two color arrays were performed and each individual array included a target sample and a control sample.

Rhesus macaque model of hCoV-EMC respiratory infection

Project description:Microarray analysis of peripheral blood mononuclear cells (PBMCs), lungs, and lung lesions collected over the course of hCoV-EMC infection of 6 rhesus macaques. 6 rhesus macaques were infected intratracheally with hCoV-EMC. PBMCs were collected at days 0, 1, 3, and 6, and lungs were collected from serial sacrifices of 3 animals each at day 3 and day 6. Infection produced a mild-moderate, self-limiting respiratory infection, and was not lethal. We performed microarray analysis (using Agilent Rhesus arrays) on all lungs, lung lesions, and PBMCs collected for the study.

Senescent fibroblasts and innate immune cell activation might play a role in the pathogenesis of elderly atopic dermatitis

Project description:Elderly atopic dermatitis is a subtype of AD defined by age (over 60 years), which has different clinical manifestations and distinct inflammatory patterns from AD in infants, children, and adolescents/adults. However, the molecular characteristics of elderly AD remain to be clarified.We sought to characterize the molecular features of skin lesions and peripheral blood mononuclear cells (PBMCs) in patients with AD across various age groups, focusing on elderly AD.We identified the molecular phenotypes of skin lesions and PBMCs in elderly individuals with AD. Fibroblasts, innate immune cells, and SASP might play important roles in the pathogenesis of elderly AD.

Gene Expression Profiling in Peripheral Blood in Untreated New Onset Systemic Juvenile Idiopathic Arthritis

Project description:Systemic Juvenile Idiopathic Arthritis (sJIA) has been strongly associated with macrophage activation syndrome (MAS). To better understand the pathogenesid of sJIA and to facilitate the search for MAS biomarkers, we examine gene expression profiles in untreated new onset sJIA. 17 new onset sJIA patients were included in the study. 5 of the 17 patients showed evidence of subclinical MAS and 2 eventually developed overt MAS. Keywords: disease versus control Peripheral blood mononuclear cells (PBMCs) were separated using a Ficoll gradient from the 17 new onset sJIA patients and 30 normal control. RNA was extracted from the PBMCS and subsequently hybridized to Affymetrix microarrays

Molecular insights on the peripheral and intra-tumoral effects of systemic high dose rIL-2 (Aldesleukin) administration for the treatment of metastatic melanoma

Project description:We have previously shown that within tumors, recombinant interleukin-2 (rIL-2, Aldesleukin) consistently activates tumor-associated macrophages and up-regulates interferon stimulated genes (ISGs) while inducing minimal migration, activation or proliferation of T-cells. These effects are independent of tumor response to treatment. Here, we prospectively evaluated transcriptional alterations induced by rIL-2 in peripheral blood mononuclear cells (PBMCs) and within melanoma metastases by serially comparing pre- to post-treatment samples in 13 patients. We also compared transcriptional differences among lesions displaying different responsiveness to therapy, focusing on 2 lesions decreasing in size and 2 remaining stable (responding lesions) compared to non-responding ones. As previously described, the effects of rIL-2 were dramatic within PBMC, while effects within the tumor microenvironment were lesion-specific and limited. However, distinct signatures specific to response could be observed in responding lesions pre-treatment that were amplified following rIL-2 administration. These signatures match the functional profile observed in other human or experimental models in which immune-mediated tissue-specific destruction (TSD) occurs underlying a common pathways leading to rejection. Moreover, the signatures observed in pre-treatment lesions were qualitatively similar to those associated with TSD underlining a determinism to immune responsiveness that depends upon the genetic background of the host or the intrinsic genetic makeup of individual tumors. This is the first prospectively collected insight on global transcriptional events occurring during high-dose rIL-2 therapy in melanoma metastases responding to treatment. Evaluated transcriptional alterations induced by rIL-2 in peripheral blood mononuclear cells (PBMCs) (n=34) and within melanoma metastases (n=30) by serially comparing pre- (n=34) to post-treatment (n=30) samples in 13 patients.
