Insights

Co-signaling molecules regulate T cell responses in psoriasis. Targeting these molecules offers promising new immunotherapies for this chronic inflammatory disease.

Area of Science:

  • Immunology
  • Dermatology
  • Inflammation Research

Background:

  • Psoriasis is a chronic, systemic immune-mediated inflammatory disease affecting skin and joints.
  • Co-signaling molecules are crucial for T cell response magnitude and function.
  • These molecules are categorized as co-stimulatory (e.g., CD28, CD40) and co-inhibitory (e.g., CTLA-4, PD-1).

Purpose of the Study:

  • To review the role of co-signaling molecules in psoriasis pathogenesis.
  • To explore the therapeutic potential of targeting co-signaling molecules for psoriasis treatment.

Main Methods:

  • Literature review of co-signaling molecules in psoriasis.
  • Analysis of molecular mechanisms in immune modulation.
  • Evaluation of current and emerging immunotherapies.

Main Results:

  • Co-signaling molecules (CD28, CD40, OX40, CD27, DR3, LFA-1, LFA-3, CTLA-4, PD-1, TIM-3) significantly impact psoriasis.
  • These molecules modulate T cell immunity, cytokine production, and Treg differentiation.
  • Immunotherapies targeting co-signaling molecules show significant progress.

Conclusions:

  • Co-signaling molecules are key players in the immune pathogenesis of psoriasis.
  • Targeting co-signaling pathways presents a promising therapeutic strategy for psoriasis management.

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

Types of Signaling Molecules01:32

Types of Signaling Molecules

In multicellular organisms, many molecules transmit signals between cells to pass information. These signals vary in complexity and include small peptides, nucleotides, steroids, fatty acid derivatives, and dissolved gases such as nitric oxide. Some signaling molecules diffuse through the plasma membrane to act locally between neighboring cells or travel long distances. Others remain attached to the cell surface, transmitting information to other cells only when they make contact. In some...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

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...

Paracrine Signaling01:21

Paracrine Signaling

Paracrine signaling allows cells to communicate with their immediate neighbors via secretion of signaling molecules. Such a signal can only trigger a response in nearby target cells because the signal molecules degrade quickly or are inactivated if not taken up. Prominent examples of paracrine signaling include nitric oxide signaling in blood vessels, synaptic signaling of neurons, the blood clotting system, tissue repair/wound healing, and local allergic skin reactions. Nitric oxide as a...

T Cell Types and Functions01:24

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Assembly of Signaling Complexes01:30

Assembly of Signaling Complexes

Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
Interaction domains in cell signaling
Interaction domains recognize exposed features of their binding partners containing post-translationally modified sequences,...
