Investigations on the T and B lymphocyte surface architecture were carried out by means of scanning electron microscopy (SEM) in 102 patients with various chronic internal diseases such as chronic hepatitis, diabetes mellitus, systemic lupus erythematosus, chronic lymphocytic leukemia, a.o. The clinical and biological examination performed in these cases reveled also some cytochemical, biochemical and immune disturbances. Emphasis is laid on the superiority of SEM, as compared with the E and EAC rosette tests, for the identification of T and B lymphocytes. Moreover, by detecting certain cellular anomalies, SEM can provide useful indications regarding the diagnosis, prognosis and therapy of the above mentioned diseases. Association of SEM with other clinical and laboratory investigations can either confirm, disapprove or even enhance the value of the morphological findings by electron microscopy.

Immunogold Electron Microscopy

Immunoelectron microscopy utilizes immunogold labeling of endogenous proteins with specific antibodies to detect and localize these proteins in cells and tissues. The procedure provides insights into the distribution and quantification of protein under different stimulation conditions offering clues about their functions. Conjugating highly electron-dense gold particles with primary or secondary antibodies allow antigen detection on and within cells, with high resolution and specificity.

Special Features of Adaptive Immunity

The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
B Cell Activation and Differentiation01:24

B Cell Activation and Differentiation

The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

Defense Against Bacterial Pathogens

The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
