horror autotoxicus
A varied group of chronic illnesses that
involves almost every human organ system
Autoimmunity
Seen when demonstrable immunoglobulins
of —— display specificity for self-antigen or autoantigens that contribute to pathogenesis of a cell disorder
cytotoxic T cells
Autoimmunity begins with an abnormal interaction of
——— with autoantigens or self-antigens
T and B lymphocyte
Other causes of autoimmunity: __________________________________. These factors may alter antigens which the body perceived as non-
self-antigen
Bacteria, viruses (infection), drugs and
radiation (environmental exposure)
Ex of autoimmunity caused by bacteria
post streptococcal glomerulonephritis,
this is the clonal deletion of relevant effector cells. If ever there’s a deletion, it will lead to self-reactive lymphocytes
Genetic susceptibility
B and T cells differentiation wherein there’s what
we call processed ________________.
central tolerance
Also seem to influence the antigen recognition or non-
recognition by determining the peptides that can be
presented to the T cells
Major Histocompatibility Complex
Autoimmune disease of brain.
Multiple sclerosis
Organ specific autoimmunity.
Multiple sclerosis and Type 1 DM
Autoimmune hemolytic anemia can be cause by a drug called
Cephalosporin dapsone
These medications Acts as haptens
Cephalosporin dapsone
Autoimmune hemolytic anemia leads to the activation of
Complement cascade
This is seen most commonly in condition to secondary viral infection.
Paroxysmal cold hemoglobinuria
IgG protein reacts with RBC in colder parts
of the body producing complement
component binding
Paroxysmal cold hemoglobinuria
essential for the development of
red blood cell
Vitamin B12
A chronic disease resulting from the non-
absorption of vitamin B12
Pernicious anemia
Pernicious anemia results to the inability to secrete intrinsic factors. What is the basic abnormality of the disease?
Severe atrophic gastritis
substance secreted by stomach that will enable the body to absorb
vitamin B12.
Intrinsic factor
is most common in late
adult life
Pernicious anemia
This is the main problem why we cannot secrete the intrinsic factor. Presence of this leads to the diagnosis of pernicious anemia
IF-blocking antibody
Autoantibodies to platelets bind to many of the
major platelet membrane glycoproteins
