Middle East respiratory syndrome coronavirus (MERS-CoV) poses a global health threat. Research focuses on the MERS-CoV spike glycoprotein (S) for developing effective vaccines and therapeutics.

Area of Science:

  • Virology
  • Immunology
  • Public Health

Background:

  • Middle East respiratory syndrome coronavirus (MERS-CoV) has caused over 2,200 infections and significant mortality since 2012.
  • No licensed vaccines or therapeutics are available, highlighting an urgent need for medical interventions.
  • The MERS-CoV spike glycoprotein (S) is crucial for viral entry and a key target for immune responses.

Purpose of the Study:

  • To review recent advancements in MERS-CoV therapeutics and vaccines targeting the S glycoprotein.
  • To discuss structural insights into MERS-CoV S protein-antibody interactions.
  • To identify challenges and strategies for translating MERS-CoV research into clinical applications.

Main Methods:

  • Literature review of studies on MERS-CoV monoclonal antibodies and vaccine candidates.
  • Analysis of structural data on MERS-CoV S protein-antibody complexes.
  • Discussion of current research trends and future directions in MERS-CoV intervention.

Main Results:

  • Development of monoclonal antibodies and candidate vaccines targeting the MERS-CoV S glycoprotein.
  • Structural studies reveal mechanisms of humoral immunity against MERS-CoV.

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Anatomy of Respiratory System II: Lower Respiratory Tract

The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

The Respiratory System01:16

The Respiratory System

The respiratory system is comprised of the organs that enable breathing. Air enters the nostrils and mouth, followed by the pharynx (throat) and larynx (voice box), which lead to the trachea (windpipe). In the thoracic cavity, the trachea splits into two bronchi that allow air to enter the lungs. The bronchi split into progressively smaller bronchioles and terminate in small groups of tiny sacs in the lungs called alveoli, where gas exchange occurs.

Anatomy of Respiratory System I: Upper Respiratory Tract

The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract....

Antibody Structure

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
The Y-Shaped Structure of Antibodies Consists of Four Polypeptide Chains
Antibodies consist of four polypeptide chains: two identical heavy...
