Neurons: The Cell Body and the Dendrites

6.7K
A typical nerve cell comprises three main components: the cell body, dendrites, and the axon. The cell body, also known as the soma or perikaryon, serves as the central biosynthetic hub housing a nucleus surrounded by cytoplasm containing organelles commonly found in most cells. Notably, Nissl bodies, clusters of the rough endoplasmic reticulum and free ribosomes responsible for protein synthesis, are distinctive features of the neuronal cell body. As neurons age, aggregates of a brown pigment...

Loss of Tumor Suppressor Gene Functions

5.9K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

13.9K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

T Cell Types and Functions01:24

T Cell Types and Functions

2.2K
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...

Metabolic Rate01:25

Metabolic Rate

1.2K
The human body is a powerhouse of energy, with every cell performing numerous functions that require energy. This energy production and consumption is measured by the metabolic rate, which quantifies the total heat generated by all the body's chemical reactions and mechanical work. This measurement helps to determine the rate of kilocalorie (kcal) consumption needed to fuel all ongoing activities.
The Basal Metabolic Rate (BMR) measures the energy expended at rest.
Several factors influence...

Area of Science:

  • Immunology
  • Cancer Biology
  • Metabolic Pathways

Background:

  • Dendritic cells (DCs) are crucial for initiating immune responses against cancer.
  • The tumor microenvironment presents significant challenges to DC function.
  • Tumors exploit molecular and metabolic pathways to impair DC activity and evade immune surveillance.

Purpose of the Study:

  • To review recent findings on how tumors manipulate DC homeostasis and function.
  • To examine current strategies aimed at enhancing DC function for antitumor responses.
  • To highlight the importance of DC metabolism in cancer immunotherapy.

Main Methods:

  • Literature review of recent studies on DC function in the tumor microenvironment.
  • Analysis of molecular pathways and metabolic programs exploited by tumors.
  • Evaluation of emerging therapeutic strategies targeting DCs.

Main Results:

  • Tumors employ diverse molecular and metabolic strategies to suppress DC function.
  • These suppressive mechanisms hinder the development of effective antitumor immunity.
  • Novel strategies are being developed to overcome tumor-induced DC dysfunction.

Conclusions:

  • Modulating DC metabolism and activity within tumors is critical for improving cancer immunotherapy.
  • Targeting DC pathways offers a promising avenue for enhancing T cell-mediated antitumor responses.
  • Further research into DC-tumor interactions can lead to more effective cancer treatments.
