Summary
The kinase AMPK guides how effector T cells adapt their metabolism when nutrients are scarce. This metabolic adaptation is vital for effective immune responses in living organisms.
Area of Science:
- Immunology
- Cellular Metabolism
- Molecular Biology
Background:
- Cellular metabolism reprogramming is essential for T cell function in response to environmental changes.
- Understanding the molecular mechanisms governing T cell metabolic adaptation is critical for controlling immune responses.
Purpose of the Study:
- To investigate the role of the kinase AMPK in directing the metabolic adaptation of effector T cells.
- To determine the contribution of AMPK-mediated metabolic changes to in vivo immune responses.
Main Methods:
- Investigated effector T cell metabolism under nutrient-limited conditions.
- Utilized molecular biology techniques to study the function of the kinase AMPK.
- Assessed immune responses in vivo in relevant models.
Main Results:
- The kinase AMPK was identified as a key regulator of effector T cell metabolic adaptation.
- AMPK activity was shown to be crucial for T cells facing nutrient deprivation.
- AMPK-dependent metabolic reprogramming was linked to effective immune responses in vivo.
Conclusions:
- AMPK plays a critical role in metabolic adaptation of effector T cells during nutrient limitation.
- AMPK signaling is a significant contributor to the overall efficacy of immune responses in vivo.

6.5K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

5.1K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

9.4K
Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.

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...
