Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

69.3K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

7.7K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Chemical Signaling in the Endocrine System

7.7K
A signaling cascade is a series of events that facilitates the transmission of information within or between cells, culminating in a targeted response in the recipient cell. As chemical messengers, hormones are pivotal in initiating and modulating these intricate signaling cascades based on their solubility.
Lipid-soluble hormones, such as steroid hormones, demonstrate an intracellular action. These hormones traverse cell membranes due to their lipid nature. Once inside the target cell, they...

Physiological Foundation of Stress01:24

Physiological Foundation of Stress

893
Stress triggers a coordinated physiological response involving the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. This dual activation ensures that the body is prepared for both immediate and prolonged stress management. The process begins with the perception of a stressor. This initial phase activates the SNS, leading to the rapid release of adrenaline (epinephrine) from the adrenal glands.
Role of the Sympathetic Nervous System
Adrenaline triggers the...

Diversity in Cell Signaling Responses01:22

Diversity in Cell Signaling Responses

8.3K
The physiological function of a cell and cellular communication are outcomes of a range of extrinsic signals, intracellular signaling pathways, and cellular responses. No two cell types express the same repertoire of signaling components. Receptors are highly selective for their cognate ligands, but once activated, they can alter multiple cellular processes such as DNA transcription, protein synthesis, and metabolic activity. 
Graded and Abrupt Responses
Some signaling systems generate...

Secondary Messengers in Hormone Action01:26

Secondary Messengers in Hormone Action

5.9K
Water-soluble hormones cannot cross the plasma membrane, so they rely on protein receptors that span the membrane to trigger intracellular signaling pathways. These pathways then activate second messengers inside the cell, including cAMP or calcium ions.
Many hormones bind to transmembrane G protein-coupled receptors that connect to regulatory G proteins. These G proteins can then activate enzymes such as adenylyl cyclase or phospholipase C. Adenylyl cyclase converts ATP to cAMP, activating...

Area of Science:

  • Plant Science
  • Environmental Stress Biology
  • Crop Physiology

Background:

  • Plants are sessile and constantly exposed to environmental challenges.
  • Field conditions often involve simultaneous abiotic and biotic stresses, unlike controlled research settings.
  • Developing crops tolerant to combined stresses is critical for agriculture.

Purpose of the Study:

  • To review recent research on plant acclimation mechanisms to combined environmental stresses.
  • To highlight the role of plant hormones in mediating responses to stress combinations.
  • To discuss the flexible coordination of hormone signaling pathways under diverse stress scenarios.

Main Methods:

  • Review of recent scientific literature on plant stress responses.
  • Analysis of studies investigating plant hormone signaling under combined stresses.
  • Synthesis of findings on the interplay between hormone pathways and other regulatory mechanisms (e.g., ROS).

Main Results:

  • Plant hormones are key regulators of plant responses to combined stresses.
  • Hormone signaling pathways exhibit flexible coordination, adapting to stress type, timing, and plant species.
  • Interactions between different hormone signals and with pathways like ROS are crucial for acclimation.

Conclusions:

  • Understanding complex hormone signaling under combined stresses is vital for crop improvement.
  • Tailored crop development requires knowledge of species-specific responses to multiple environmental factors.
  • Future research should focus on elucidating these intricate signaling networks for enhanced stress tolerance.
