Thus, although macrophages are known to produce IL-18 constitutively, the discrete pattern of expression of IL-18 only in macrophages within the periductal infiltrate is suggestive of an inducible phenomenon associated with the microarchitectural organization of periductal aggregates.
Our results illustrate that different populations of taste cells exhibit discrete patterns of gene expression and support a model whereby each taste quality is detected by a specific taste cell population expressing the requisite set of gene products necessary to sense, transmit, and code that particular taste.
Together with several new candidate genes, our results identify discrete patterns of gene expression linked to frequency- and steroid-dependent plasticity of hair cell auditory sensitivity.
Network analyses based on these preselected features produced a complex graph with 8,836 nodes, further reduced into 87 clusters of discrete patterns of gene expression (see Additional file 3).
The role of FBNs in anti-sporozoite defense has not been investigated, but the discrete patterns of FBN expression observed at 24 hours and 19 days after P. berghei infection suggests that distinct FBN subsets are involved in mosquito immune responses to ookinetes and sporozoites.
Moreover, discrete patterns of chemokine receptor expression are detected in the synovial tissue.
However, it has relatively little relevance for attachment theory itself, which "neither requires nor predicts discrete patterns of attachment".
Thus to compare patterns of expression, we grouped observations into three discrete categories: cases in which (i) both paralogs are not expressed, (ii) one gene is expressed and the other is not, and (iii) both genes are expressed.
Classifying the patterns of expression of genes during chili pepper fruit development and ripening in the discrete space of 27 possible patterns allows for a more detailed analysis of the complex changes in the transcriptome.
