5 Things to Consider when Developing Clinical Biomarkers

5 Things to Consider when Developing Clinical Biomarkers | Immunology Diagnosis | Scoop.it
Developing cellular biomarkers is particularly challenging when it comes to biomarker validation, because flow cytometry has limitations regarding sample stability and multiplexing. Moreover, the development of highly multiplex flow cytometry assays is time-consuming and expanding existing panels can be quite cumbersome. ChipCytometry is a new, imaging based, cytometry technology bridging the gap between biomarker discovery and clinical biomarker validation through flexible “sequential singleple

New MRD Assay Helps Move Testing Forward in Multiple Myeloma Research | Page 1

New MRD Assay Helps Move Testing Forward in Multiple Myeloma Research | Page 1 | Immunology Diagnosis | Scoop.it
An improved assay for assessing MRD status in patients with multiple myeloma is contributing to the momentum for using MRD as a surrogate endpoint for survival in clinical trials and as a tool with the potential to help guide therapy choices.
Alfredo Corell's insight:

In March, the International Myeloma Foundation (IMF) launched a new, automated flow cytometry test that is sensitive to 10-6 (1 cell in a million) and provides a computerized printout of MRD levels. The new test offers a more reliable method of assessing MRD status in an area that currently lacks standardization, said Durie, who is cofounder and chair of the IMF. - See more at: http://www.onclive.com/publications/oncology-live/2014/april-2014/new-mrd-assay-helps-move-testing-forward-in-multiple-myeloma-research/1#sthash.0RGCy54i.dpuf

Rapid Flow Cytometric Prenatal Diagnosis of Primary Immunodeficiency (PID) Disorders

Rapid Flow Cytometric Prenatal Diagnosis of Primary Immunodeficiency (PID) Disorders: http://t.co/FVhdPQz5vY #flowcytometry
Alfredo Corell's insight:

February 2014


Abstract
Objectives

Primary Immunodeficiency diseases (PID) are a heterogeneous group of inherited disorders of immune system. Immunophenotypic evaluation of PIDs using flowcytometry provides important clues for diagnosis of these disorders, though confirmation requires identification of underlying molecular defects. Prenatal diagnosis (PND) forms an important component of management in families affected with severe PID. However, molecular diagnostic facilities for each of these diseases are not available and may not be possible to perform in all cases. In such scenario we opted for phenotypic prenatal diagnosis by cordocentesis for families with index case having immunophenotypically well characterized PID.

Methods

Normal reference ranges of lymphocyte subsets, CD 18/CD11 integrins on leukocytes, MHC class II expression and oxidative burst activity of fetal neutrophils at 18 weeks of gestation were previously established on 30 cord blood samples. PND was performed in 13 families with PIDs. Maternal contamination was ruled out by VNTR analysis.

Results

Out of 13 fetuses, nine were found to be unaffected (three cases with leukocyte adhesion deficiency (LAD-I), four cases with severe combined immunodeficiency diseases (SCID), one with X-linked agammaglobulinemia (XLA), and one with chronic granulomatous disease (CGD)] and three were found to be affected (one with T-B+NK-SCID, one with MHC class II deficiency and one with LAD-I). Diagnosis was confirmed by testing the cord blood samples after delivery and further follow-up of the children. In one family diagnosis could not be offered due to maternal contamination. No procedure related complications were observed.

Conclusion

Flowcytometry offers rapid and sensitive method for prenatal diagnosis and genetic counseling for selected phenotypically well characterized PID in cases where molecular diagnostic facilities are not available.

Alfredo Corell's insight:

While you’re running around taking silly photos with your smartphone of what you ate for lunch today, a researcher at the University of California, Los Angeles, has found a way to photograph microscopic cell samples using a cell phone camera. Dr. Aydogan Ozcan, a professor and head of the Ozcan Research Group at UCLA, and his team of electrical scientists and bioengineers have developed a device that fits onto any camera-equipped cell phone that could benefit doctors and scientists in countries with limited clinical supplies. The research findings were recently published in the Journal of Visualized Experiments(JoVE, subscription required).

Flow cytometry assessment of the purity of human retinal pigment epithelial primary cell cultures

Flow cytometry assessment of the purity of human retinal pigment epithelial primary cell cultures | Immunology Diagnosis | Scoop.it

Culturing of human retinal pigment epithelial cells (hRPE) is the initial step in cell therapy of some retinal diseases. To transfer these cells into clinical use, it is necessary to guarantee that they are well differentiated and contamination free. Fluorescence microscopy is the easiest method to do this, but it is associated with operator subjectivity, and the results are highly variable. The aim of this study was to demonstrate the practicality of implementing flow cytometry (FC) analysis to determine the purity of human RPE primary cell cultures. An ARPE19 cell line, human skin fibroblasts, hRPE, and human corneal epithelial cells were analysed by FC to determine the percentage of the hRPE population expressing RPE65 and epithelial and fibroblast proteins. The cell viability and DNA content also were determined. FC analysis showed that the hRPE cells were healthy, stable, and expressed RPE65 protein in the study working conditions. The density of RPE65 protein expression decreased during passages 2 to 10, which was confirmed using a Western blot technique. However, the hRPE cells did not express the 112-kDa epithelial and fibroblast proteins in the current working conditions. These findings suggested that FC facilitates a detailed analysis of human RPE primary cell cultures, a necessary step in developing new cell therapies for retinal diseases.

How To Differentiate T-Regulatory Cells (Tregs) By Flow Cytometry | Expert Cytometry | Cell Gating Strategies

How To Differentiate T-Regulatory Cells (Tregs) By Flow Cytometry | Expert Cytometry | Cell Gating Strategies | Immunology Diagnosis | Scoop.it
T-reg or T-regulatory cells have direct roles in both autoimmunity and responses to pathogens. Here we'll show you how to quantify Tregs.
Alfredo Corell's insight:
Gating Strategies For Defining Tregs By Flow Cytometry

The standard Treg gating strategy for both mouse and human samples (after first gating out doublets and gating on live cells) includes the antigens CD3, CD4, CD25, FOXP3, and CD127.

When looking solely at antigen expression, Tregs are often defined as CD3+, CD4+, CD25hi, FOXP3+, and CD127lo (shown in the figure below as Option 1). Using these markers, a clear population is often visible from samples such as mouse splenocytes and human PBMC.

Article first published online: 20 DEC 2013

DOI: 10.1002/cyto.a.22429

© 2013 International Society for Advancement of Cytometry

Alfredo Corell's insight:

This issue of Cytometry contains three reviews that further celebrate the longstanding, intense, and happy marriage between Cytometry and Immunology, as highlighted recently during the XV International Congress of Immunology, held in Milan, Italy, August 22–27, 2013. Scanning the scientific contributions of the Conference reveals that cytometric technology was used in the vast majority of abstracts and presentations. In other words, very few scientists did not switch on one or more lasers! It is obvious, that nowadays very few studies in the field of Immunology are possible without techniques based upon single cell analysis.

ESCCA Summer Schools represent our new policy towards the development of residential, full-immersion courses which will pave the way to the specific certification of technical and academical operators, widely felt as a fundamental step for laboratory accreditation.

An International course will be also organized in English, for the benefit of the operators from smaller Countries that cannot enjoy the support of a local society.
