An accurate measurement of the immune status in patients with immune system
disorders is critical in evaluating the stage of diseases and tailoring drug
treatments. The functional cellular immunity test is a promising method to
establish the diagnosis of immune dysfunctions. The conventional functional
cellular immunity test involves measurements of the capacity of peripheral blood
mononuclear cells to produce pro-inflammatory cytokines when stimulated ex vivo.
However, this "bulk" assay measures the overall reactivity of a population of
lymphocytes and monocytes, making it difficult to pinpoint the phenotype or real
identity of the reactive immune cells involved. In this research, we develop a
large surface micromachined poly-dimethylsiloxane (PDMS) microfiltration membrane
(PMM) with high porosity, which is integrated in a microfluidic microfiltration
platform. Using the PMM with functionalized microbeads conjugated with antibodies
against specific cell surface proteins, we demonstrated rapid, efficient and
high-throughput on-chip isolation, enrichment, and stimulation of subpopulations
of immune cells from blood specimens. Furthermore, the PMM-integrated
microfiltration platform, coupled with a no-wash homogeneous chemiluminescence
assay ("AlphaLISA"), enables us to demonstrate rapid and sensitive on-chip
immunophenotyping assays for subpopulations of immune cells isolated directly
from minute quantities of blood samples.
