Final answer:
AIDS, caused by HIV, results in cellular immune dysfunction by weakening the immune system and making individuals susceptible to opportunistic infections.
Step-by-step explanation:
The disorder that results in cellular immune dysfunction is AIDS (Acquired Immune Deficiency Syndrome).
AIDS is caused by the human immunodeficiency virus (HIV), which weakens the immune system by infecting and destroying antibody-producing cells.
As a result, individuals with AIDS become vulnerable to a variety of opportunistic infections.
