Bacterial Toxins

Bacterial Toxins

Bacterial toxins are sophisticated virulence factors that enable pathogenic bacteria to interact with, invade, and damage host tissues. These toxins fall broadly into two types: protein exotoxins, which are secreted into the environment and target specific host receptors, and lipopolysaccharide endotoxins, which are structural components of the bacterial outer membrane released primarily during bacterial lysis or membrane shedding. Exotoxins generally act more selectively, binding to cell...

Targeted Cancer Therapies

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Modified-Release Drug Delivery Systems: Site-Targeted

Modified-Release Drug Delivery Systems: Site-Targeted

Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.

Types of Toxins

Types of Toxins

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Area of Science:

Neurosurgery
Molecular Biology
Cell Biology

Background:

Selective neural lesions are crucial for understanding brain function.
Current methods may lack specificity or precision.
Targeted toxins offer a novel approach to lesioning specific neuron populations.

Purpose of the Study:

To present three molecular neurosurgery protocols for creating selective neural lesions.
To detail the mechanism of targeted toxins in inducing cell death.

Main Methods:

Utilizing targeted toxins composed of a targeting moiety (vector) and a cytotoxic moiety (cytotoxin).
The cytotoxic moiety functions as an enzyme inactivating the large ribosomal subunit, inhibiting protein synthesis.
Three protocols: suicide transport, immunolesioning, and neuropeptide-toxin conjugates.

Main Results:

Targeted toxins effectively induce cell death by irreversibly inhibiting protein synthesis.
A single molecule of free cytotoxin is sufficient to kill a cell (all-or-none effect).
Demonstrated protocols for anatomically restricted and type-selective lesions.

Conclusions:

Molecular neurosurgery provides a precise method for creating selective neuronal lesions.
Targeted toxins offer a versatile tool for neuroscience research and potential therapeutic applications.
