Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.0K
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...

Targets for Drug Action: Overview

8.4K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Skin Cancer01:30

Skin Cancer

5.0K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Asthma: Pathogenesis and Management

898
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

5.3K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Antiasthma Drugs: Leukotriene Modifiers01:19

Antiasthma Drugs: Leukotriene Modifiers

1.4K
Leukotriene modifiers, or cysteinyl leukotriene receptor antagonists, are medications used to manage chronic asthma. These agents target specific inflammatory mediators produced during arachidonic acid metabolism, an essential process in generating inflammation in the body.
Leukotriene modifiers work through two distinct mechanisms:

Area of Science:

  • Dermatology and immunology, focusing on skin pathophysiology and therapeutic interventions.

Background:

  • Acne management traditionally targets sebogenesis, hyperkeratinization, Cutibacterium acnes, and inflammation.
  • Recent research highlights the roles of specific cytokines, including IL-1β, IL-17, IL-23, and TNFα, in acne and wound healing.
  • Acne sequelae, such as atrophic and hypertrophic scars, are influenced by genetic, systemic, local, and lifestyle factors, with pro-inflammatory cytokines playing a key role.

Purpose of the Study:

  • To explore novel therapeutic strategies for acne and its sequelae, particularly severe acne and scarring.
  • To investigate the potential of biological antibodies targeting specific cytokines involved in acne pathophysiology and scar formation.

Main Methods:

  • Review of current understanding of acne pathogenesis and immunological aspects.
  • Identification of key molecular targets, including IL-1β, IL-17, IL-23, TNFα, TGFβ, IL-6, MMP, and IGF-1.
  • Analysis of the role of these targets in acne and the development of hypertrophic scars.

Main Results:

  • Biological antibodies targeting IL-1β, IL-17, IL-23, and TNFα show promise for treating severe acne.
  • Cytokines such as TGFβ, IL-6, MMP, and IGF-1 are implicated in keloid and hypertrophic scar formation.
  • Targeting these cytokines with biological antibodies may offer future strategies for scar prevention and treatment.

Conclusions:

  • Future acne management should focus on etiological factors, emphasizing early, aggressive treatment of inflammation to minimize scarring.
  • Biological therapies targeting specific cytokines represent a promising avenue for managing severe acne and its disfiguring sequelae.
  • Further research into the microbiome and growth factors like IGF-1 may yield additional therapeutic options.
