Disclosed is a method to recover an antigen presenting cells (APCs) and immune cells rich mixture (AIM) from peripheral blood mononuclear cells (PBMC) mobilized with one or more cell adhesion inhibitors for the preparation of an AIM vaccine or an AIM adoptive immunotherapy preparation. In addition, AIM mobilization can be enhanced by priming, simultaneously or in sequence, one or more of a combination of different chemical compounds, cytokines, hormones, growth factors, etc. The interaction of chemokines and chemokine receptors enable tumor cells attachment or in close proximity to antigen presenting cells and immune cells which possess similar receptors in a micro niche environment. Severing the chemokine/chemokine receptor linkage by a cell adhesion inhibitor will release these specifically primed cell mixtures into the peripheral blood. The collection of these cells from the peripheral blood has never been described and is the basis of this invention. AIM cells can either be used alone or better still, be induced into more target specific preparations with additions, modifications and incubation, pre or post cell adhesion inhibitors mobilization, with vaccines, different target specific antigens, peptides, chemotherapeutic agents, oncolytic viral therapeutic agents, cytokines, co-stimulatory molecules, anti-regulatory T cell therapeutic agents, anti-CTLA4, anti-PD1 molecules and other methodologies of immunological enhancement known to the art. The AIM vaccine or AIM adoptive immunotherapy preparation can then be used, but not limited to, the treatment of cancer and other diseases.

A method for the early diagnosis of breast, lung, pancreatic and colon growths and cancers as well as conditions associated with donor and recipient organ transplants, both before and after transplantation to identify and allow treatment of possible transplanted organ rejection and other disease conditions related and unrelated to the transplantation, compares the gene expression patterns from a patient's peripheral blood monocytes-lymphocyte's gene system with either the similar gene expression patterns of a normal person, or with the similar gene expression patterns of a person known to have the condition being screened for. Differences between the patient's gene expression patterns for particular genes and the normal patterns indicates the presence of the condition with the number of differences indicating the probability of the condition. Similarities between the patient's gene expression patterns for those particular genes and the patterns of a person known to have the condition indicates the presence of the condition with the number of similarities indicating the probability of the condition. Portions of the method may be performed with the use of a microfluidic machine.
