Cofactors and Coenzymes

Cofactors and Coenzymes

Enzymes require additional components for proper function. There are two such classes of molecules: cofactors and coenzymes. Cofactors are metallic ions and coenzymes are non-protein organic molecules. Both of these types of helper molecule can be tightly bound to the enzyme or bound only when the substrate binds.

Regulation of Expression Occurs at Multiple Steps

Regulation of Expression Occurs at Multiple Steps

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Area of Science:

Immunology
Cell Biology
Developmental Biology

Background:

Monocytes and their derived cells (macrophages, dendritic cells) are vital for host defense, immune regulation, and tissue repair.
Increasing evidence points to significant heterogeneity within monocyte populations, explaining their diverse functional roles.
Mechanisms governing the functional programming of distinct monocyte subsets are not fully understood.

Purpose of the Study:

To review how monocyte origins and developmental factors influence their phenotypic and functional characteristics.
To explore the impact of extrinsic signals, transcriptional regulators, epigenetic, and metabolic mechanisms on monocyte programming.
To highlight the potential for therapeutic immune modulation by resolving monocyte heterogeneity.

Main Methods:

Review of recent studies on monocyte heterogeneity, origins, and functional programming.
Analysis of extrinsic signals, transcriptional, epigenetic, and metabolic influences.
Examination of developmental pathways during homeostasis and inflammatory responses.

Main Results:

Monocyte subsets arise from distinct developmental pathways during homeostasis.
Inflammatory stimuli differentially affect progenitor cells during emergency responses.
Understanding monocyte ontogeny and heterogeneity is crucial for targeted therapies.

Conclusions:

Resolving monocyte heterogeneity and understanding their developmental programming offers promise for therapeutic immune modulation.
Further research, including multiparametric single-cell profiling, is needed to define mechanisms of monocyte subset production and identity.
Targeting specific monocyte subsets could lead to novel interventions for infectious diseases, inflammation, cancer, and aging.
