To invest in energetically demanding life history stages, individuals require a substantial amount of resources. Physiological traits, particularly those related to energetics, can be useful for examining variation in life history decisions and trade-offs because they result from individual responses to environmental variation. Leptin is a protein hormone found in mammals that is proportional to the amount of endogenous fat stores within an individual.

Article Synopsis
- Line A chickens show increased resistance to bacterial and protozoan infections, with their heterophils exhibiting more effective immune responses compared to line B.
- When stimulated with TLR agonists, heterophils from line A display distinct cytokine and chemokine mRNA expression patterns, indicating differences in immune signaling pathways.
- Research using microarray analysis reveals that line A heterophils express significantly higher levels of immune-related genes involved in the TLR pathway, suggesting this may enhance their innate immune response to pathogens like Salmonella enteritidis.
