An unusual response of hamster lymphocytes to PHA

Here we present a longitudinal evaluation of golden hamsters infected intraperitoneally (IP) or via intragingival (IG) with L. infantum-Luc by bioluminescent imaging and by PCR. Hamsters were evaluated 1 day post infection (1 dpi), 1 week after infection (8 dpi), and 3 weeks after infection (22 dpi) and euthanized at the 50th dpi and 8 months post...

Pronuclear (PN) injection of the clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated protein-9 nuclease (CRISPR/Cas9) system is a highly efficient method for producing genetically engineered golden Syrian hamsters. Herein, we describe the detailed PN injection protocol for the production of gene knockout hamsters with the CRISPR/Cas9...

T lymphocyte migration occurs during homing to lymphoid organs, exit from the vasculature, and entering into peripheral tissues. Here, we describe a protocol that can be used to analyze T lymphocyte migration in...

Unusual results are those that have a very low chance of occurring. Unusual results can be identified using probabilities and the range rule of thumb. In problems involving probability, unusual results can be observed in 2 instances – an unusually high number of successes or an unusually low number of successes.
According to the range rule of thumb, any value above or below two standard deviations, 2σ  from the mean, μ  is considered unusual.
Maximum unusual value =...

The video showcases a flow cytometry-based assay for assaying immunodominance in cytotoxic T lymphocytes or CTL responses. Injected fluorescent target cells exhibit varying fluorescence corresponding to immunogenic epitopes. Post-spleen collection and sorting reveal a reduction in high-intensity fluorescent cells, confirming immunodominance in CTL...

The z score is one of the three measures of relative standing. It describes the location of a value in a dataset relative to the mean. z scores are obtained after the standardization of the values in a dataset. The z score for the mean is 0.
 This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...
