Keywords: T cells, Lymphocytes, TCR, Cell Surface, Cytotoxic T cells, Antigen Presenting Cells (APC), Major Histocompatibility Complex (MHC)

T cells are a category of lymphocytes that differ from other lymphocytes because of the unique T cell receptor (TCR) present on the cell surface. Together with co-receptors (CD4 for helper T cells and CD8 for cytotoxic T cells), the TCR enables T cells to detect and react to peptide antigens, which are pathogens digested by antigen presenting cells (APCs) and displayed on major histocompatibility complex (MHC) molecules.

Keywords: Amino Acid, Plasma, Glutamine Metabolism, Pathway, Cancer Cells, Transporter, Glutaminolysis, Lipid Systhesis, Cellular Energy

As the most abundant free amino acid in the plasma, glutamine participates in a variety of biochemical processes, such as protein and lipid synthesis, cellular energy production, and nitrogen and carbon donation.

Glutamine metabolism occurs in proliferating cells, particularly cancer cells. The process begins with glutamine entering the cell through the amino acid transporter ASCT2/SLC1A5. In the mitochondria, glutamine undergoes glutaminolysis, which includes reaction steps from the citrate cycle and the malate-aspartate shuttle.

Keywords: Fluorescence, Cellular Autofluorescence, NADPH, Collagen, Elastin, Flavins, Mitochondria, Lysosomes, Pacific Blue

The common problem for all fluorescence-based cell detection methods is the cells’ natural fluorescence. Cellular autofluorescence is due to the presence of various biological structures, such as collagen, elastin, NADPH, flavins, mitochondria, and lysosomes, which usually absorb in UV to blue range (355-488 nm) and emit in the blue to green range (350-550 nm). Therefore, autofluorescence interferes with analysis by reducing signal sensitivity and resolution of fluorochromes that operate in that range – FITC, GFP, and Pacific Blue to name a few.

Keywords: Allergy, Pllen, Allergic Disorder, Dust Mites, Allergic Rhintics, Allergic Conjunctivitis, Asthma, Hay Fever

Allergies are when the body’s immune system has a hypersensitive reaction towards innocuous substances called allergens. Common allergens include dust mites, pollen, mold, food, and animal dander, which could trigger allergic disorders such as allergic asthma, hay fever, allergic rhinitis, anaphylaxis, allergic conjunctivitis, and contact dermatitis. When a susceptible individual is newly exposed to an allergen, the immune system undergoes allergic sensitization.

Keywords: Cancer immune response, tumor cell activity, programmed cell death, apoptosis pathways

In normal conditions, mutated antigens from tumor cells will lead to the activation of T cells that bind to and trigger apoptosis in target cancer cells. On the surface of T cells are PD-1 (programmed cell death-1) receptors whose ligands include PD-L1 and PD-L2. Together, PD-1 and PD-L1/PD-L2 are involved with inhibiting T cell response so that the immune response is only initiated when necessary, avoiding chronic autoimmune inflammation. However, tumor cells have utilized the PD-1/PD-L1 pathway to resist anticancer immune responses by producing abnormally high levels of PD-L1. When the PD-L1 ligands bind to the PD-1 receptors on T cells, the T cells become deactivated and anti-tumor activity is obstructed.

Cancer stem cells (CSCs), also known as tumor-initiating cells (TICs), are a subpopulation of cancer cells that possess the self-renewal and multi/pluripotency properties similar to that of normal stem cells. They have been identified to be tumorigenic and linked with inducing metastasis. Several molecular signaling pathways are associated with governing stem cell homeostasis. Normally, these pathways are highly regulated. However, an increasing number of these signaling pathways have been discovered to become dysfunctional in CSCs, which include the JAK/STAT, Hedgehog, Wnt, Notch, NF-κB, PI3K and PTEN signaling pathways. In certain cases, cross-talk between different pathways contribute to CSC population maintenance. Download the pathway map poster to learn more.

If you are performing IHC experiments, you may need to optimize your antigen retrieval methods. Techniques generally fall into two main categories: protease-induced epitope retrieval (PIER) and heat-induced epitope retrieval (HIER). In general, HIER has a much higher success rate and is recommended over PIER methods. The protocol for HIER must be optimized for each sample tissue, fixation method, and antigen. This method is especially time-, temperature-, buffer-, and pH-sensitive, and the best condition must be determined empirically. Here is a step-wise protocol that may be helpful for your immunohistochemistry experiment.
