Abstract
Methods for obtaining a tuberculosis assessment in a subject are provided. Aspects of the methods include identifying a subpopulation of a cellular sample of the subject having an expression level for a tuberculosis host biomarker below a threshold expression level to produce a biomarker signature; and obtaining a tuberculosis assessment for the subject from the biomarker signature. Aspects of the invention further include reagents, devices, systems, and kits thereof that find use in practicing the subject methods are provided. The methods and compositions find use in a variety of applications, including diagnosis and monitoring of TB.
Claims15
A method of obtaining a tuberculosis assessment for a subject, the method comprising:
- identifying a subpopulation of a cellular sample of the subject having an expression level for a tuberculosis host biomarker below a threshold expression level to produce a biomarker signature for the cellular sample, wherein the tuberculosis host biomarker is selected from the group consisting of CD120b, CD126 and CD62L and combinations thereof;
- and
- obtaining a tuberculosis assessment for the subject from the biomarker signature.
A kit comprising:
- a collection of two or more detectably labeled tuberculosis host biomarker specific binding members, wherein the tuberculosis host biomarkers are selected from the group consisting of CD120b, CD126, CD62L, fMLP r and combinations thereof.
A flow cytometry system comprising:
- a flow cytometer comprising a flow cell;
- a light source configured to direct light to an assay region of the flow cell;
- a first detector configured to receive light of a first emission wavelength emitted by a first detectably labeled tuberculosis host biomarker specific binding member present in a cellular sample in the assay region;
- and
- a signal processing module configured to receive signals from the first detector and output a result of whether a subpopulation of cells bound to the first detectably labeled tuberculosis host biomarker specific binding member is present in the cellular sample.
A computer readable medium comprising programming for execution by a computer, comprising:
- instructions for analyzing signals produced by a detector configured to receive light of a emission wavelength emitted by a detectably labeled tuberculosis host biomarker specific binding member to produce data;
- instructions for storing the data on a computer readable medium;
- and
- instructions for outputting the data.
